The format CR2 (Canon raw version 2) was developed in 2004 by Canon Inc. with the purpose of storing digital images. The main difference between CR2 and more common formats like JPG or PNG is that CR2 does not offer ready to view pictures. Raw formats like CR2 are advantageous mainly because CR2 enables the user to post process the image easier than ready to view without worrying about the quality loss. CR2 files are based on the TIFF (Tagged Image file) file specification. CR2 format as well as other raw images, can be viewed using programs like Adobe Photoshop, Paint Shop Pro, digiKam etc.
A .sgi extension file saves images in the original Silicon Graphics Image format. These files are originated from the library of SGI images that were there on every Silicon Graphics machine. SGI files are also referred to as RGB, IRIS or Irix RGB., .sgi image files can be saved in 8-bit color, 16-bit or 32-bit color. GIMP has the compatibility to read and write .sgi extension files and also has a dialog box that pops up to help select the compression type. The preferred compression is RLE and while it reduces the file size, it is advisable to check once it is done to ensure that the file size is indeed reduced as sometimes the size is more than the actual file size.
FreeFileConvert uses tuned encoding for CR2 to SGI conversions, preserving clarity while trimming file size. Finished audio streams instantly across phones, tablets, desktops, and modern browsers without extra tweaks.
Upload CR2 files from desktop, tablet, or cloud storage, queue multiple jobs, and let the converter finish autonomously. Return whenever convenient to download synchronized SGI results on any device you rely on.
Process up to 5 files sized 1000 MB per batch without splitting queues manually. Mixed-format uploads convert together, producing consistent SGI audio with dependable progress tracking.
CR2 format is the upgraded version of CRW, it offers the best quality to size ratio. What makes it so different from other formats is the fact that all the colours are recorded either in 12 or 14 bits and lossless compression is being used. The primary benefit of using CR2 format is that it allows professional photographers and designers the ability to modify pictures without any drawbacks, unlike some other file formats.
SGI is a generic raster image file format that stores black and white, gray scale and color images. Images in the SGI format are generic bitmap images that have the capacity to store 8 to 32 bits per pixel. The file size of the images can be compressed with the Run-length encoding (RLE) technique. The .sgi extension files begin with a 512 byte header that is fixed and is followed by the pixel data. There is a scan-line table in case of compressed images with the compressed pixel data following the table. The scan-line offset table indicates the start of every scan line in the data of a compressed image. Lots of bit planes, alpha channel data and / or color maps may be included in the files with .sgi extension. Contrary to the top-down order followed by other formats, the pixel data in .sgi extension file follows the bottom-up order.
