Background & Context

    • Common MIME types: application/pcx, image/pcx
    • Paintbrush PCX format.
    • Raster image format.
    • Legacy format used on Microsoft DOS.
    • Binary format.
    • Compresses image data using run-length encoding after restriction to a color map.
    • Can also store true color raster images.
    • Developed by ZSoft as part of the PC Paintbrush application.

Import & Export

  • Import["file.pcx"] imports a PCX file, returning an Image object.
  • Import["file.pcx",elem] imports the specified element from a PCX file.
  • The import format can be specified with Import["file","PCX"] or Import["file",{"PCX",elem,}].
  • Export["file.pcx",expr] exports an image, graphics, or any other expression as a raster image to PCX.
  • When exporting Wolfram Language graphics or arbitrary expressions to PCX, the resulting image has the same raster size as its displayed form.
  • Because PCX is a raster image format, all fonts are rasterized on export.
