Compress Raw Images

Cookie usage is extremely common and normal, but new laws require us to inform you. RAW or unprocessed image files contain all of the information captured by a camera's sensor chip. The function imwrite saves the image to the specified file. There is also support of Blackmagic Design CinemaDNG RAW 3:1 and 4:1 formats. Images quality, sizes and multiple resolution screens. Paste image data Paste an image from your clipboard into this website. Resize images to fit within specified pixel dimensions. File Formats provides background information about different types of file formats, and contains additional topics that provide information on the following:. ~window_name (string, default: name of the image topic) The name of the display window. theora_image_transport ("theora") - Streaming video using the Theora codec. It's great but what's about images? A Picture is Worth a Thousand Words, and bad optimized images ruin your blog or website speed. If your file system supports holes (for example in ext2 or ext3 on Linux or NTFS on Windows), then only the written sectors will reserve space. Raw disk image format (default). You can make from your raw file a full jpg, which will keep full quality. Dotphoton's patented technology allows to reduce the size of raw image files by up to 10 times and still preserve all image information. 1MB in size. LEADTOOLS is the most complete compression SDK and is fastest software-only JPEG solution available. This is a form of lossless compression for images. Use ImageMagick to healthily compress JPEG images. , for JPEG formats (with the exception of some JPEG2000 images that use lossless compression). Saves the active image or stack as raw pixel data without a header. CineForm RAW was added in 2005, the first to offer substantial compression directly from CFA Bayer image sensor data. If you used Adobe Photoshop, it will have already done a really great job at reducing the image size, however, you can still likely shave off another 5-10% of image size by using a compression app like ImageOptim and/or ShortPixel. (9 replies) Hi, I need to transfer a local raw image to another datacenter. The best method of resizing and compressing images is by using Photoshop. Shooting raw video has a host of huge benefits with equally large challenges. Without knowing why you want to compress a RAW image file, I will have to gues You either need to buy some m. image_transport ("raw") - The default transport, sending sensor_msgs/Image through ROS. I have a 72. Upload your file and transform it. This tool also provide you a better quality and resolution of the RAW image files. Most of editors refuse to work with RAW shots. Learn More. The results of this evaluation are presented here together with comparabl. THE JPEG IMAGE COMPRESSION ALGORITHM. Because you can't easily add pixels and retain image quality, or remove the effects of compression after the fact, it's usually best to use the largest available JPEG size and the least compression available. Tool supports SATA, IDE, SAS, SCSI, SSD hard disk drives. Image compression. Or does PowerPoint compress images? More details on images, formats and sizes. For example, by default we will not compress the Icon Image Sequence Pixel Data attribute:. The big question is whether these theoretical advantages are ever visible in real life. I have been using a Word Stylesheet and RPE 2. However, contrary to conventional image compression schemes, the distortion is not measured between the original and reconstructed raw data. do planar reformats since the original raw data is discarded. To see which image formats Imager is comp TONYC /Imager-1. RAW ISO 200 The differences between a RAW versus a JPEG file are immediately apparent when you open the images in the computer. 👍 We use Imagify on the Kinsta blog and so we'll show you how it works. 1 Pure methane - CO 2 mixtures. Optimize your images and convert them to base64 online. Because you can squeeze more smaller or more compressed images onto a storage device, there may be times when you'll want to switch to the smaller size and sacrifice quality for quantity. A RAW file is the image data exactly as captured on the sensor. Goma Qualcomm Incorporated. You'll see visible compression artifacts in your image when editing highly compressed images. Lesson 6: File Size, Compression & Memory Cards. The compression used in these filetypes are specialized for images and works to reduce the data you don't see. Compression is just an opportunistic way of encoding things, and when asking for "the best compression ratio that can be achievable by lossless data compression", you need to be more specific about the context of the compression: the compression ratio is the ratio between the size of the compression and the size of a "raw" encoding, but the. Compression algorithms are most efficient when they can group a lot of similar data. Using this free online service is as easy as a click of a button! It is no more a secret that optimized images are better than the raw ones as they are better for storage, web pages, and email attachment. Look at the insets, though. The DFT of an image is given by. Text documents can be reduced in size significantly. Web app to convert RAW images to JPG. " Thank you for taking the time to read and help this early AM. Preparing Images for Web When creating images for web use, keeping the file size low is very important. The image compression algorithms most online image optimization tools use allow them to work around such limitations to provide crisp and clear images that load fast. Rawzor announces a major update to its lossless image compression software that adds support for Apple Mac OSX. The higher quality comes at a cost of larger file size. Image file compression comes in two basic types. It will also be huge. RAW image files are designed to save ALL the image data captured by the sensor with NO loss of image quality (if your exposures are good). RAW images are great, but how can you share the image online. ps To convert a raw Gray image with a 128 byte header to a portable graymap, use: gm convert -depth 8 -size 768x512+128 gray:raw image. io performs this task in an excellent way. You'll see visible compression artifacts in your image when editing highly compressed images. Without knowing why you want to compress a RAW image file, I will have to gues You either need to buy some m. Generally images are classified as the following. image_transport ("raw") - The default transport, sending sensor_msgs/Image through ROS. A digital camera shooting images in raw format provides output in the best possible quality, which means files are larger in size and take more space. choose DNG as your image format, and check the "Use Lossy Compression" box. In practical use, a compression setting of about 60% will result in the optimum balance of quality and filesize, without letting the lossy compression do too much damage. Prior to this site, they were only available in the Sun Raster format via ftp. compressed_image_transport is a plugin package for image_transport. Image compression reduces the storage space required by an Image and the bandwidth needed when streaming that image across a network. when you save your bitmap, if you save it as a jpeg file, you can alter its compression methods, changing its filesize, if you just call save, it uses the default. By default when compressing a DICOM Image file, gdcmconv will not compress the icon. Reduce (Shrink) raw image (. Advanced digital cameras can be set to create images files, stored to a memory card, in the universally shareable JPEG format, or as a RAW file. JPEG image compression is not suitable for images with sharp edges and. Learn quick tips and tricks for working with RAW image files in Windows 10, along with a list of useful applications for opening and editing image files. You can't upload RAW images to the web for people to view, they need to be converted into. Typically, images are processed (adjusted for color, white balance, exposure, etc. Compress IMAGE Compress JPG, PNG or GIF with the best quality and compression. Most image editing tools like Adobe Photoshop, On1 Photo, GIMP, Affinity Photo, and others come with built-in image compression features. Web app to convert RAW images to JPG. Compression is one of the major image processing techniques. 6 How to View RAW. Nevertheless, compressing images for the web is very easy to do with Photoshop. Free photo resizer and image compressor to crop, resize images in JPEG|PNG|GIF format to the exact pixels or proportion you specified, compress them to reduce the file sizes, making it easy to use them as your desktop wallpaper, Facebook cover photo, Twitter profile photo, avatar icons, etc. You must be at least 21 years of age to view this site, and be viewing this material in an area where no minors are present. The only difference between the two lies in how much space is actually taken up on your hard drive! Lossy Compression. Applying lossless compression to images generates the following: A lossless attribute for images that are of the GIF, BMP, RAW, or PNG file type. The forementioned Canon raw footage – about 2:42h of 23. We all hear that RAW images are bigger than JPEGs, but that bigger is in terms of the space they fill in the card or on your hard drive. The original raw file is completely restored on decompression like when using zip. However, keep in mind that for my usage case I’m shipping across a high latency / low. I have an Olympus, can display the RAW images in Olympus Viewer and used y\to be able to share the RAW images in Facebook. This article will describe three methods to convert your Raw files to DNG files. When looking at the various procedures and functions, many are. Last year, YouTube reported that users were uploading 48 hours of video to the service every minute. There are four basic steps for image compression and image restoration as outlined below. 264, but to actually see the difference side by side is something that one shouldn't pass up. In today’s post we will look at lossy vs lossless compression and the advantages and disadvantages of both methods. 998% of its colors. DNG contains raw bayer images, not grayscale images. Introduced in Oracle 10g, the UTL_COMPRESS package can be used to compress and uncompress large objects (raw, blob or bfile). It is my understanding they have been released by the Eastman Kodak Company for unrestricted usage. Simply click to select your file or drag & drop to upload, then download your smaller, optimised copy. The slices are then compressed with the JPEG 2000 image coding standard. If you?re using CS-2; open Bridge and select the RAW files you want to resize and save. And finally, Image compression happens online in a matter of seconds. ODIN is a utility for easy backup of hard drive volumes or complete hard drives under Windows. Either way, raw files are usually larger than JPEG files because any compression that is applied is lossless so there's no loss of quality through compression artefacts. Because raw images are not compressed, they take up significantly more disk space than their JPEG counterparts (usually at least twice as much). The webpage will load faster, and it saves bandwidth. The PBM documentation refers to this format as RAWBITS. JPEG is a lossy compression method widely used in digital photography. INTRODUCTION Image compression is a type of an application for data/image compression in which the basic image gets encoded with the limited bits. Why do we need Raw Image Compression on GPU? We need to compress raw stream from a camera (industrial, machine vision, digital cinema, scientific, etc. Image Quality and File Type (NEF/RAW, JPEG, and TIFF). All these images have been tested before public. Only after that we begin to process true raw data to let you correct exposure and other parameters of a photo. NEF (RAW) Compression; NEF (RAW) Bit Depth; NEF (RAW) Compression N Lossless compressed NEF images are compressed using a reversible algorithm, reducing file size by about 20–40% with no effect on image quality. I will try compressing another image at the next kernel update after using this cool procedure again. Still images are defined as ones that convey their meaning in visual terms in, e. Image compression reduces the storage space required by an Image and the bandwidth needed when streaming that image across a network. With a smaller compression rate we obtain a. Raw image data is compressed by using a lossy encoding followed by non‑adaptive Huffman compression. Raw files are named so because they are not yet processed and therefore are not ready to be printed or edited with a bitmap graphics editor. JPEG to RAW AI is exceptional at removing these artifacts while preserving natural image features: Artifacts won't be easily visible in high-quality JPEGs, but they can completely ruin an image if they are. In the box below that you should see JPEG in the box labeled SAVE AS TYPE. The result is a quality image without wasting storage or bandwidth!. Stevens and C. Modern video compression algorithms aren’t the same as the image compression algorithms you might be familiar with. It’s not only because we work with files locally (nothing is uploaded to the Internet), but also because we are able to extract embedded JPG. Today photo post production services are popular due to their possibility to economize time and retouch photos with high quality. This raw image data, what the imaging chip recorded along with the so-called meta-data (the camera settings and other technical information) is now saved to the card. ProRes RAW data rates also vary. The image size is not displayed on the screen. ABSTRACT The MIPI standard has adopted DPCM compression for RAW data images streamed from mobile cameras. It will also be huge. My goal is twofold—that this is the only guide you will ever need on the subject and that you will gain such a deep understanding on the topic that you can easily move forward in your photography. A Word about Colorspaces • Supported Formats • Pseudo Formats • Built-in Images • Built-in Patterns • Embedded Profiles. numbers of raw signal data. Image Compression, Huffman Encoding, Lossy, Lossless. The image is then sharpened to offset the softening caused by demosaicing, which is visible in the second image. An example of loss-less file compression is the compressed Tiff file format, which uses the LZW algorithm. This file has 60 Isolated raw food items that you can use in your next food related project, be it a website header, blog, article, newsletter etc. It also can record with a couple of more bits of z-axis precision (12 bits instead of 8 bits) , which is invisible unless you have a very poorly lit image and need to do horrendous curve adjustments. Text documents can be reduced in size significantly. The benefits include improved storage capacity, reduced memory bandwidth, and lower power consumption for digital still camera processors. With the image converter you can convert almost any graphic images. In Bayer RAW files, these color transforms are saved as metadata, or applied as filters during reconstruction Layer 1: Bayer CFA Sensor Data Layer 2: Demosaic Algorithm. For example, by default we will not compress the Icon Image Sequence Pixel Data attribute:. DWORD PaletteSize Contains the size, in bytes, of the color palette. io is a free online interface for rapidly and conveniently converting your images into highly optimized JPEGs using Kraken. David Shay wrote: Is there anyway to compress. Even if it was, RLE achieves poor compression ratios compared to a more modern scheme such as DEFLATE. IIQ RAW stands for Intelligent Image Quality RAW. Embed a color profile or convert a set of files to sRGB and save them as. If you really want to compress RAW files, rather than just change the resolution of the final images, then by converting them to DNG (which uses lossless compression) you will usually reduce the actual file size of your original RAW files without any loss of information. ) Note that RAW image files will require you to perform post-processing on your photographs. Raw is free from visible compression artifacts, just like JPG at the milder compression levels. How to save a JPEG (. imwrite(A,filename) writes image data A to the file specified by filename, inferring the file format from the extension. This will launch the Image Processor Window. Free online tool to convert document, image, audio, video, presentation, archive, ebook and font files from one format to another. In order to analyze raw image data, you probably will need to display memory dumps of frame buffers, image buffers and uncompressed image files. Digital cameras see and record color in a way that is different from the way humans see and register color. We evaluate all algorithms on two standard datasets of uncom-pressed video: Video Trace Library (VTL) [2] and Ultra Video Group (UVG) [1]. Other raw files can be converted to DNG so that a wider variety of software can use the images. Jpeg compression standard is a lossy compression where the quality of the image is reduced. The higher quality comes at a cost of larger file size. You’ll see your image almost immediately. A Raw File A record of the data captured by the camera sensor Unprocessed sensor data 68. If you don't know what resolution to use, try something close to 800 x 600 or 640 x 480. Prior to this site, they were only available in the Sun Raster format via ftp. If you need to recover files from a disk image, a hard drive, or another damaged device, call us at 1. 1) Scenario S 1: image compression is applied to the orig-inal image of the eye, i. If you choose the full size option when you save an image, that's about all you can do. Video Compression through Image Interpolation 3 tion baselines. The scope of this study is: 1) Is it technically feasible to compress raw biogas to at least 300 bar? 2) Has the raw biogas to be cleaned of contaminants like water vapour and H 2 S? 3 COMPRESSION OF GAS 3. 0 files, both in "Part-10 compliant" and in "raw" formats. You can do this also on the image processing page. Image Quality and File Type (NEF/RAW, JPEG, and TIFF). Berryboot Updated OS Images This is the biggest list of OS images for Berryboot. We are excited to share some early results of our research which will appear at ICML 2017. Wavelet-based compression Represent complex structures in the image Store compressed data in hierarchical format Compressing an extremely large amount of image data into a relatively small amount of compressed data Compressed image can then be sent to a device in the resolution that best fits without additional storage overhead. Now you can get the raw disk image with [affuse][3] But for some reason, mounting the raw image fails. imwrite(A,filename) writes image data A to the file specified by filename, inferring the file format from the extension. Images quality, sizes and multiple resolution screens. Jpeg XS, on the other hand, is said to have no visual loss to the image compressed. We all hear that RAW images are bigger than JPEGs, but that bigger is in terms of the space they fill in the card or on your hard drive. Of course, general purpose compression programs can be used to compress images, but the result is less than optimal. Choose a compression type and bit depth for NEF (RAW) photographs. For all practical purposes, you can think of UTL_COMPRESS as PL/SQL's means of compressing or zipping files. Images make up a very big part of the on web pages. You can get images such as JPEG, BMP, GIF, PDF, PSD, PNG, TIFF and others. When optimize option is True compress_level has no effect (it is set to 9 regardless of a value passed). compress jpg pictures, how to crop images, how to resize pictures, lossy jpeg compression, lossless png compression, compress tiff images, jpeg lossly compression, image editor file manager, compress raw files, bmp format, bitmap graphic compression compressing graphic files guide, crop pictures, png lossless compression, optimize picture. Thus, image compression must not only reduce the necessary storage and bandwidth requirements, but also allow extraction for editing, processing, and targeting particular devices and applications. So images low on detail and with few tones will compress much more than images with lots of detail and lots of different tones. The best method of resizing and compressing images is by using Photoshop. Better sharpening potential. Not bad, I suppose. , even though major movies like The Hobbit and The Amazing Spiderman could afford 3:1 if they wanted to, they chose to shoot at a lower setting of 5:1. These raw files are also sometimes called digital negatives. Up until this step, RAW image information most likely resided within the digital. RAW files are processed directly from the camera’s sensor, thus they do not use compression. Or does PowerPoint compress images? More details on images, formats and sizes. True to its name, this utility takes photo compression very seriously. Some things which appear as an image to the eye may also be made up of multiple images or not even images at all! All this means that if you want to extract images from a PDF, you need to assemble the image from all the raw data - it is not stored as a complete image file you can just rip out. A digital camera shooting images in raw format provides output in the best possible quality, which means files are larger in size and take more space. Because raw images are not compressed, they take up significantly more disk space than their JPEG counterparts (usually at least twice as much). On GPU NVIDIA GeForce GTX 1080 TI one can do JPEG compression of 24-bit 4K image within less than 0. RAW is not a compressed format, so it does need more room than a JPEG, which can be compressed. The following are code examples for showing how to use cv2. Lossy Image Compression Ratio (0028,2112) may be multi-valued if successive lossy compression steps have been applied; if so, the value order shall correspond to the multiple values of Lossy Image Compression Method (0028,2114), if present. This section provides detailed information about the image formats and compressions that ImageGear supports. The big question is whether these theoretical advantages are ever visible in real life. If you have the option, maybe the Solomon solution is for you: shoot both formats simultaneously, and fiddle with the Raw version only when necessary. Windowpane is the live-streaming social network that turns your phone into a live broadcast camera for streaming to friends, family, followers, or everyone. There are three common types of compression used on black and white scanned images:. Below are the main reasons why manufacturers provide options for RAW compression: To Save Space - this is the main reason, as the primary benefit of any type of compression is, first and foremost, space savings. During the Raw Disk Image recording process, all sectors are backed up. However, the compression and the copy processes make it quite a bit slower than raw disk images. The ability to compress camera RAW images with JPEG XR allows for high compression rates with very low loss in image. Unsurprisingly, this pays off in terms of the raw figures, with the service compacting our PNG web graphics by a mighty 48 per cent – the best in this test. Go down to the JPEG section and choose the desired level of compression 1-10 then enter 600 in both the height and width boxes. Using this free online service is as easy as a click of a button! It is no more a secret that optimized images are better than the raw ones as they are better for storage, web pages, and email attachment. They are extracted from open source Python projects. 4mp megapixels, and 14-bit precision, an uncompressed 5D III RAW image from a Canon sensor would be 41mb, while the average CR2 file from a 5D III is about 26mb, meaning a compression ratio of ~36%. Reduce the filesize of your images at once. Normal, Fine, Superfine! Too many choices! The main stumbling block in digital photography is that all the menus and choices are baffling, especially to the novice. In order to analyze raw image data, you probably will need to display memory dumps of frame buffers, image buffers and uncompressed image files. Modern video compression algorithms aren’t the same as the image compression algorithms you might be familiar with. The reason why you should use Tinypng because this is the only tool which can store partially transparent images. IIQ RAW stands for Intelligent Image Quality RAW. Based on the content of your image an optimal strategy is chosen. Yes, Raw’s a pain, and it’s unwieldy. A new window will open and you should see the file name of the image you selected in the box labeled FILE NAME. Due to limited computational capabilities in the capsule and bandwidth constraints, low-complexity and efficient compression of Bayer endoscopy images is required before transmission. Lossless compression is a class of data compression algorithms that allows the original data to be perfectly reconstructed from the compressed data. If we compress a lot, more information will be lost, but the result image size will be smaller. RAW files are so large you wouldn't want to upload them to Facebook, Photobucket, etc. There are only more or less efficient ways of representing it. 5 of radius) depends on the quality and size of the picture, this notably optimizes the size of the jpeg. Hope this article helped you, share it with others as well. 2 megapixel D200, an uncompressed NEF is about 16 megabytes; the compressed NEF is about half that size. UFRaw's configuration options can be divided into three groups: Image manipulation options that control how the raw image will be converted. So, what is the difference between the two and what advantages are offered by opting for RAW files and then post-processing your images on a computer?. This tutorial shows you how to convert KVM qcow2 disk images to raw disk images. They compress all images and videos under 16MP and 1080p while trying to retain as much information from the originals as possible. It could be helpful to reduce the weight of images, in order to use it on a website for example. Raw vs jpeg: Don't know which file format you should be using for your images. Furthermore, the method is highly efficient, leaving little material or energy to waste. For instance a 2. AFF offers two significant benefits. JPEG or TIFF). Image compression is an application of data compression that encodes the original image with few bits. The module also provides a number of factory functions, including functions to load images from files, and to create new images. RAW image files are designed to save ALL the image data captured by the sensor with NO loss of image quality (if your exposures are good). Image Compression, Huffman Encoding, Lossy, Lossless. Free Online Raw Converter. The DFT of an image is given by. But 95% of my images that I end up keeping are just for the memory and I won't be doing alot of post-processing work to them. Lightroom CC doesn't have a lot of options for saving images. The higher quality comes at a cost of larger file size. But after conversion, I archive the RAW files on DVD. As one of the first working professional photographers to transition to digital photography, I ran into a lot of head wind. Initially, the LSB algorithm is used to embed the payload bits into the cover image to derive the stego-image. LZW compression is the compression of a file into a smaller file using a table-based lookup algorithm invented by Abraham Lempel, Jacob Ziv, and Terry Welch. Amazon Photos and Amazon Drive support most of the commonly used file types and formats for photos and videos. Library ROS API. So i want to know is there any image program which supports to compress ISO image. A given RAW photo, taken by a SLR camera, might have a dimension of 5835 by 3890 pixels, and its file size is 27 MB. A disk image can be created or restored. Save R Objects Description. So then it seems logical that images obtained from 14-bit lossless RAW files should have a larger dynamic range and be more detailed and nuanced than images from 12-bit lossy RAW files. the Microsoft Raw Image. Configure the compression settings and image splitting and enter a description for the archive. Compress JPEG images and photos for displaying on web pages, sharing on social networks or sending by email. That being said, our image has 3072 dimensions. CR2, Nikon’s. It is often used where the graphic might be changed by another person or where the image contains layers of graphics that need to be kept separate from each other. We have implemented a scheme for compressing floating-point images that is fast, robust, and automatic, that allows random access to pixels without decompressing the whole image, and that generally has a scientifically negligible effect on the noise present. The RAW black photo. So, there is no longer need for built-in compression software that you have to install on your desktop computer. Since 2008, we have worked with teams and clients spread across US, UK, China, South Korea, Serbia, Australia, India, Singapore, Denmark, Saudi Arabia, Israel and UAE. io performs this task in an excellent way. It will take a little longer to read, and especially write, as the algorithm is computationally intensive, but can reduce total file size by as much as 40%. Simply put, compression is a process which trades CPU cycles for bytes. Image Compression, Huffman Encoding, Lossy, Lossless. Before you attempt to reduce the size of an image, first consider whether an image is even necessary. Convertio — advanced online tool that solving any problems with any files. quality in 85; progressive (comprobed compression) a very tiny gausssian blur to optimize the size (0. 32-bit images are saved as floats and RGB images are saved in three bytes per. You can't upload RAW images to the web for people to view, they need to be converted into. 2 Advanced System Technology Overview • Image Compression is the Image Data Elaboration branch dedicated to the image data representation • It analyzes the techniques allowing to reduce the. but the more you compress this type of image, the more. Even if it was, RLE achieves poor compression ratios compared to a more modern scheme such as DEFLATE. Compressing an Image in Photoshop Elements Photoshop Elements and Photoshop are almost identical in their Web image capabilities, and that's a good thing. To convert a TIFF image to a PostScript A4 page with the image in the lower left-hand corner, use: gm convert -page A4+0+0 image. save writes an external representation of R objects to the specified file. It contains uncompressed, raw image data that can be adjusted for exposure and white balance using software that supports the format. By adding LEADTOOLS to your project, your user’s will experience faster execution, require less storage, and save money on bandwidth. Not an actual compression format by itself, RAW is encoding used by PBM, PGM, and PPM images to represent images in binary form (versus the plain text form employed by the ASCII encoding). More-over, the recent growth of large volume of image data in. In particular, the submodule scipy. Your choice (or lack thereof) of file format helps to determine the size of the file and amount of compression applied to the image. Below are suggestions and resources for reducing the number of images in your creative and for optimizing the images you need. Typically, images are processed (adjusted for color, white balance, exposure, etc. With this information one can write a basic SAR processor. When you press the shutter on your digital camera the image must be saved as a digital file. A file with the DNG file extension is most likely an Adobe Digital Negative Raw Image file. Figure 12: RAW image (interleaved) 150 x 113 pixels = 50KB. You can’t resize this image because of poor compressing. It is an intelligent way of turning the full 16 bit image data captured by the camera into a compact RAW file format. io performs this task in an excellent way. Some cameras compress these files, others don't. Sony RAW Driver is a program to display Sony RAW data* (ARW/SR2/SRF files) on Windows ® 7 ⁄ Windows ® 8. Fast CinemaDNG Processor software can import 8/10/12/14/16-bit DNG and PGM images with Bayer pattern created by 3rd-party applications. As I'm sure you understand, no application can Save a RAW file. Taking a RAW file and ending up with a JPG is a simple thing to do in Lightroom, but there's something to wrap your head around first. The partial in camera accelerated de‑mosaic allows for extremely efficient compression. If the image has indexed colors you should also specify the number of colors used. , A problem-solving approach to find a satisfactory solution where finding an optimal or exact solution is impractical or impossible , A data compression algorithm that allows the original data to be perfectly reconstructed from the compressed data, A data compression method that uses inexact approximations, discarding some data to represent the content. SVG images are example of an image format which is not natively compressed. The fact-checkers, whose work is more and more important for those who prefer facts over lies, police the line between fact and falsehood on a day-to-day basis, and do a great job. Today, my small contribution is to pass along a very good overview that reflects on one of Trump’s favorite overarching falsehoods. Namely: Trump describes an America in which everything was going down the tubes under  Obama, which is why we needed Trump to make America great again. And he claims that this project has come to fruition, with America setting records for prosperity under his leadership and guidance. “Obama bad; Trump good” is pretty much his analysis in all areas and measurement of U.S. activity, especially economically. Even if this were true, it would reflect poorly on Trump’s character, but it has the added problem of being false, a big lie made up of many small ones. Personally, I don’t assume that all economic measurements directly reflect the leadership of whoever occupies the Oval Office, nor am I smart enough to figure out what causes what in the economy. But the idea that presidents get the credit or the blame for the economy during their tenure is a political fact of life. Trump, in his adorable, immodest mendacity, not only claims credit for everything good that happens in the economy, but tells people, literally and specifically, that they have to vote for him even if they hate him, because without his guidance, their 401(k) accounts “will go down the tubes.” That would be offensive even if it were true, but it is utterly false. The stock market has been on a 10-year run of steady gains that began in 2009, the year Barack Obama was inaugurated. But why would anyone care about that? It’s only an unarguable, stubborn fact. Still, speaking of facts, there are so many measurements and indicators of how the economy is doing, that those not committed to an honest investigation can find evidence for whatever they want to believe. Trump and his most committed followers want to believe that everything was terrible under Barack Obama and great under Trump. That’s baloney. Anyone who believes that believes something false. And a series of charts and graphs published Monday in the Washington Post and explained by Economics Correspondent Heather Long provides the data that tells the tale. The details are complicated. Click through to the link above and you’ll learn much. But the overview is pretty simply this: The U.S. economy had a major meltdown in the last year of the George W. Bush presidency. Again, I’m not smart enough to know how much of this was Bush’s “fault.” But he had been in office for six years when the trouble started. So, if it’s ever reasonable to hold a president accountable for the performance of the economy, the timeline is bad for Bush. GDP growth went negative. Job growth fell sharply and then went negative. Median household income shrank. The Dow Jones Industrial Average dropped by more than 5,000 points! U.S. manufacturing output plunged, as did average home values, as did average hourly wages, as did measures of consumer confidence and most other indicators of economic health. (Backup for that is contained in the Post piece I linked to above.) Barack Obama inherited that mess of falling numbers, which continued during his first year in office, 2009, as he put in place policies designed to turn it around. By 2010, Obama’s second year, pretty much all of the negative numbers had turned positive. By the time Obama was up for reelection in 2012, all of them were headed in the right direction, which is certainly among the reasons voters gave him a second term by a solid (not landslide) margin. Basically, all of those good numbers continued throughout the second Obama term. The U.S. GDP, probably the single best measure of how the economy is doing, grew by 2.9 percent in 2015, which was Obama’s seventh year in office and was the best GDP growth number since before the crash of the late Bush years. GDP growth slowed to 1.6 percent in 2016, which may have been among the indicators that supported Trump’s campaign-year argument that everything was going to hell and only he could fix it. During the first year of Trump, GDP growth grew to 2.4 percent, which is decent but not great and anyway, a reasonable person would acknowledge that — to the degree that economic performance is to the credit or blame of the president — the performance in the first year of a new president is a mixture of the old and new policies. In Trump’s second year, 2018, the GDP grew 2.9 percent, equaling Obama’s best year, and so far in 2019, the growth rate has fallen to 2.1 percent, a mediocre number and a decline for which Trump presumably accepts no responsibility and blames either Nancy Pelosi, Ilhan Omar or, if he can swing it, Barack Obama. I suppose it’s natural for a president to want to take credit for everything good that happens on his (or someday her) watch, but not the blame for anything bad. Trump is more blatant about this than most. If we judge by his bad but remarkably steady approval ratings (today, according to the average maintained by 538.com, it’s 41.9 approval/ 53.7 disapproval) the pretty-good economy is not winning him new supporters, nor is his constant exaggeration of his accomplishments costing him many old ones). I already offered it above, but the full Washington Post workup of these numbers, and commentary/explanation by economics correspondent Heather Long, are here. On a related matter, if you care about what used to be called fiscal conservatism, which is the belief that federal debt and deficit matter, here’s a New York Times analysis, based on Congressional Budget Office data, suggesting that the annual budget deficit (that’s the amount the government borrows every year reflecting that amount by which federal spending exceeds revenues) which fell steadily during the Obama years, from a peak of $1.4 trillion at the beginning of the Obama administration, to $585 billion in 2016 (Obama’s last year in office), will be back up to $960 billion this fiscal year, and back over $1 trillion in 2020. (Here’s the New York Times piece detailing those numbers.) Trump is currently floating various tax cuts for the rich and the poor that will presumably worsen those projections, if passed. As the Times piece reported:
