package require Tk 


package require img::pcx ?1.4?

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.


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. 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

      detected automatically.

      of the special options listed in section PCX OPTIONS.
