packagerequireimg::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 [https://www.tcl.tk/man/tcl9.0/TkCmd/photo.html] image type.

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

       All of the above means that in a call like imagecreatephoto ?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 of option -format is treated as a list and may contain any of the  special  options
       listed in section Options.

       The package img::tga is a sub-package of Img. It can be loaded as a part of the complete Img support, via
       packagerequireImg, or on its own, via packagerequireimg::tga.
