can`t save tga without alpha

max.m · July 2nd, 2009

hi there, i am working on an animation and want to save the images as uncompressed tga`s. now i face the problem, that i want to save the tga`s without alpha channel, and it seems to be impossible.
i uncheck premult. alpha and split alpha, but in 8, 16, and 32 bit i always get the alpha mask within the image.
tried it with png and tif and it worked without problems.
known issue or am i missing something?

what difference does it make whether you get it or not?

to answer a question with a question leads to nowhere.
i got the answer in the meanwhile, for all who are interrested.
when saving, in the tga's image attributes, choose 24 bits-per-pixel (it's not the actual colour depth, it only means that you'll save three 8 bit channels) instead of 32. it will only store rgb without alpha. alternatively you can check alpha split, and the alpha will be saved to another file instead of being stored with the rgb output.

Perhaps he was curious as was I.
