NAME¶
img-tga - Img, Truevision Targa Format (tga)
SYNOPSIS¶
package require
Tk
package require
img::tga ?1.4?
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).
