NAME

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

SYNOPSIS

       package require Tk

       package require img::tga  ?1.4?

       image create photo ?name? ?options?

________________________________________________________________________________________________________________

DESCRIPTION

       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.

       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.

       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.

SUPPORTED TGA TYPES

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