Programs to write a PCX file:

• MATHEMATICA includes an Export[filename,object] command that can save a graphics object as a PCX file.
• MATLAB can write a PCX file with commands like

  
              IM(:,:,1) = red data;
              IM(:,:,2) = green data;
              IM(:,:,3) = blue data;
              imwrite ( IM, 'file.pcx', 'PCX' )
            

  .

  
              [ X, map ] = capture ( figure_handle );
              imwrite ( X, map, 'file.pcx', 'PCX' )
            

  .

Programs to convert a PCX file to another format:

• The ImageMagick, program convert can convert a PCX file to BMP, CGM, EPS, FIG, FITS, GIF, JPG, PBM, PDF, PGM, PNG, PNM, PPM, PS, RGB, TIF or XBM format.
• GIMP, the GNU Image Manipulation Program, can read a PCX file and convert it to a variety of other graphics formats.
• xv can read a PCX file and convert it to a variety of other graphics formats.

Programs to convert another format to a PCX file:

• fig2dev can convert a FIG file to a PCX file by a command like

              fig2dev -L pcx input.fig > output.pcx
            

• GIMP, the GNU Image Manipulation Program, can read a variety of other graphics formats and convert them to PCX format.
• xv can read a variety of other graphics formats and convert them to PCX format.
