TGA (file format)


The Targa graphics file format is primarily used for the storage of 24- and 32-bit truecolor images.

General File Format Specifications


Raster Image Format




None, RLE

Color Depth

1- to 32-bits


RLE compressed images can be read by Doom 3. Since RLE is a lossless form of compression, it can be used without degrading image quality.

24-bit images cannot make use of an alpha channel. Each channel requires 8 bits. In order to make use of an alpha channel you must save your image in 32-bit.

Photoshop 7 does not save transparency information into an alpha channel when dealing with targa images. You must download the updated Targa export plugin from Adobe . All other versions of Photoshop work correctly.
