img-pcx(3tk)


NAME

   img-pcx - Img, Paintbrush Format (pcx)

SYNOPSIS

   package require Tk

   package require img::pcx  ?1.4?

   image create photo ?name? ?options?

______________________________________________________________________________

DESCRIPTION

   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

   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.

SUPPORTED PCX TYPES

            1-bit pixels: Black and White.
            8-bit pixels: Grayscale or indexed.
           24-bit pixels: True-color (RGB, each channel 8 bit).

           List of currently supported features:

           Type   |     Read      |     Write     |
                  | -file | -data | -file | -data |
           ----------------------------------------
            1-bit | Yes   | Yes   | No    | No    |
