The ZSoft PCX Standard: Run-Length Encoding and Planar Graphics
Created in 1985 by ZSoft Corporation for PC Paintbrush on MS-DOS and documented under the ZSoft PCX specification on Wikipedia↗, the .pcx container became the first widely adopted raster image format for IBM PC-compatible personal computers. During the 1980s and early 1990s, PCX served as the foundational graphic standard across early MS-DOS games, desktop publishing packages, fax software, and early Windows applications.
Every valid PCX file starts with an exact 128-byte header beginning with manufacturer byte 0x0A, followed by the version number, encoding method (where 1 signifies PCX Run-Length Encoding), bits per pixel per plane, image boundary coordinates (Xmin, Ymin, Xmax, Ymax), horizontal and vertical DPI metrics, a 16-color EGA palette table, and the number of color planes. Image data is encoded using a compact byte-level RLE algorithm: if the top two bits of a byte are set (0xC0), the lower 6 bits define the run count (1 to 63), followed immediately by the raw pixel or index value.
Because modern web browsers, smartphones, and graphic software suites have phased out native PCX decoders, accessing legacy art, archival faxes, and historical game textures requires conversion. Utilvo bridges this divide with an ultra-fast client-side PCX decoder. Running entirely in your browser memory via typed arrays and HTML5 Canvas, our engine reconstructs 1-bit monochrome, 16-color EGA, 256-color VGA, and 24-bit Truecolor PCX files into universal modern standards with zero server uploads and zero data latency.
