       img-tga - Img, Truevision Targa Format (tga)


       package require Tk

       package require img::tga  ?1.4?

       image create photo ?name? ?options?



       The  package  img::tga 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::tga.

       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 Truevision Targa
       Format (tga). More specifically img::tga extends Tk's photo image type.

       The name of the  new  format  handler  is  tga.   This  handler  provides  new  additional
       configuration options. See section TGA OPTIONS for more detailed explanations.

       All of the above means that in a call like

       image create photo ?name? ?options?

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

       [2]    The format name tga 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 TGA OPTIONS.


               24-bit pixels: True-color (RGB, each channel 8 bit).
               32-bit pixels: True-color with alpha channel (RGBA, each channel 8 bit).

               List of currently supported features:

               Type   |     Read      |     Write     |
                      | -file | -data | -file | -data |
               24-bit | Yes   | Yes   | Yes   | Yes   |
               32-bit | Yes   | Yes   | Yes   | Yes   |

               All images types may be either uncompressed (Targa-Type 2) or
               run-length encoded (Targa-Type 10).


       The handler provides the following options:

       -verbose bool
              This option is supported for reading and writing.

              If  set to true, additional information about the loaded/stored image is printed to
              stdout. Default is false.

       -compression type
              This option is supported for writing only.

              Set the compression mode to either none or rle.  Default is rle.

       -matte bool
              This option is supported for reading and writing.

              If set to false, a matte (alpha) channel is  ignored  during  reading  or  writing.
              Default is true.
