this class provides methods for loading targa-file (tga) images. |
|
556 | 41 |
|
37 | 42 |
Limitations: |
556 | 43 |
not fully tested (I only had a few targa files to check things) |
44 |
only supports 8,24 and 32 bits/pixel formats; alpha channel is ignored |
|
210 | 45 |
Image saving not supported |
37 | 46 |
|
47 |
I had two tga files to test this code with - it may not work with |
|
556 | 48 |
other targa files (it certainly does not work with 1/16 bit images). |
299 | 49 |
|
37 | 50 |
Suggestions: adapt & use the pbmplus library here. |
