TGA (file format)
Description
The Targa graphics file format is primarily used for the storage of 24- and 32-bit truecolor images.
General File Format Specifications
| Type | Raster Image Format |
|---|---|
| Extension | *.TGA |
| Compression | None, RLE |
| Color Depth | 1- to 32-bits |
Notes
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.
