NAME

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

SYNOPSIS

       package require Tk

       package require img::tga  ?1.3?

       image create photo ?name? ?options?

DESCRIPTION

       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.

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).
