Synopsis

  • package require img::tga ?2.0?

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. This handler provides new additional configuration options. See section 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 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 package require Img, or on its own, via package require img::tga.

Supported Types

This format handler supports the following image types:

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