Img, Truevision Targa Format (tga)


package require Tk

package require img::tga  ?1.4?

image create photo ?name? ?options?


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?

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


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).

 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).

-verbose bool
