DESCRIPTION

       package require img::pcx.

       Like  all  packages  of  Img it does not provide new commands, but extends the existing Tk
       command image so that it supports files containing raster images in the Paintbrush  Format
       (pcx). More specifically img::pcx extends Tk's photo image type.

       The name of the new format handler is pcx.

       The  package  img::pcx is a sub-package of Img. It can be loaded as a part of the complete
       Img support, via package require Img, or on its own, via package require img::pcx.

       This handler provides new additional configuration options. See section  PCX  OPTIONS  for
       more detailed explanations.

       All of the above means that in a call like

       image create photo ?name? ?options?

       [1]    Image data in pcx format (options -data and -file) is detected automatically.

       [2]    The format name pcx is recognized by the option -format.  In addition the value for
              the option is treated as list and may contain any of the special options listed  in
              section PCX OPTIONS.
