About formats

RAS (Sun Raster) is a raster image format developed by Sun Microsystems for their SunOS and Solaris Unix workstations, dating to approximately 1982. Sun Raster files store 2D bitmap images with support for 1-bit monochrome, 8-bit indexed color (with a color map), 24-bit true color (BGR byte order), and 32-bit XBGR (with an unused alpha byte). The format uses a 32-byte header containing a magic number (0x59a66a95), width, height, bit depth, data length, raster type (indicating compression), color map type, and color map length, followed by the optional color map data and the pixel data. RAS supports three encoding modes: standard (uncompressed, with each scanline padded to a 16-bit boundary), byte-encoded (run-length encoded using a simple escape-code scheme), and RGB (uncompressed with RGB rather than BGR byte order). Sun Raster was the native image format for Sun's window system and later the OpenWindows desktop environment, serving as the standard format for screenshots, icons, backgrounds, and application graphics on Sun workstations throughout the 1980s and 1990s. One advantage is the format's representation of Unix workstation computing heritage: Sun Raster files from the SunOS/Solaris era document the visual culture of an important computing platform that drove advances in networking, multiprocessing, and graphics workstation design. The format's straightforward structure is another practical strength — the 32-byte header and simple encoding make RAS files easy to parse and convert, even with custom code. RAS files are supported by ImageMagick, GIMP, XnView, and other image processing tools.

JPG is the most common file extension for images compressed with the JPEG standard, published by the Joint Photographic Experts Group as ISO/IEC 10918-1 in September 1992. The three-letter .jpg extension became dominant due to the 8.3 filename limitation of MS-DOS and early Windows, while .jpeg is the full-length variant — both extensions represent identical file contents and compression. JPEG applies lossy compression using the discrete cosine transform (DCT), dividing images into 8x8 pixel blocks, transforming them into frequency coefficients, quantizing to discard visually insignificant data, and entropy-coding the result. Users control the compression level: higher quality retains more detail at larger file sizes, while lower quality achieves dramatic size reduction with increasing visible artifacts in complex textures. The format supports 24-bit true color (16.7 million colors) and 8-bit grayscale, with Exif metadata embedding camera model, exposure settings, orientation, GPS location, and creation timestamp. One advantage is unmatched device compatibility — JPG is the native output format of virtually every digital camera and smartphone, and is displayed by every image viewer, browser, and operating system in existence. Efficient photographic compression is another strength: real-world photographs with smooth gradients and complex textures compress extremely well under DCT, typically achieving 10:1 reduction at high visual quality. JPG images power the vast majority of photographic content across the web, email, social media, and digital archives worldwide.
