PCX (.pcx)

  • Import and Export fully support Version 5 of the PCX format.


    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 and ExportImport and Export

  • Import["file.pcx"] imports a PCX file, returning an Image object.
  • 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.
  • Import["file.pcx",elem] imports the specified element from a PCX file.
  • Import["file.pcx",{elem,suba,subb,}] imports a subelement.
  • Import["file.pcx",{{elem1,elem2,}}] imports multiple elements.
  • The import format can be specified with Import["file","PCX"] or Import["file",{"PCX",elem,}].
  • Export["file.pcx",expr,elem] creates a PCX file by treating expr as specifying element elem.
  • Export["file.pcx",{expr1,expr2,},{{elem1,elem2,}}] treats each as specifying the corresponding .
  • Export["file.pcx",expr,opt1->val1,] exports expr with the specified option elements taken to have the specified values.
  • Export["file.pcx",{elem1->expr1,elem2->expr2,},"Rules"] uses rules to specify the elements to be exported.
  • See the reference pages for full general information on Import and Export.
  • ImportString and ExportString support the PCX format.


  • General Import elements:
  • "Elements" list of elements and options available in this file
    "Rules"full list of rules for each element and option
    "Options"list of rules for options, properties, and settings
  • Data representation elements:
  • "Data"array of color values
    "Graphics"Graphics object representing an image
    "Image"raster image, given as an Image object
    "GrayLevels"array of normalized gray-level values
    "RGBColorArray"array of RGBColor objects
  • Import and Export by default use the element for PCX files.
  • Advanced Import elements:
  • "BitDepth"bits used to represent each color channel in the file
    "ColorSpace"color encoding used in the file
    "ImageSize"raster dimensions
