PCX, standing for Paintbrush Bitmap Image, is a raster image format developed by ZSoft Corporation for their PC Paintbrush graphics program. Initially released in the 1980s, PCX was one of the first widely used bitmap image formats on IBM PC compatible computers. The format supports 1-bit monochrome, 4-bit palette, 8-bit palette, and 24-bit true color images, allowing for a wide range of colors and shades.
