Image module saves 8 bit only

my script loads a 24 bit targa with the Image Load command, then changes some pixel colors and saves

in the blender image window i can see the image in full color but when i open it with irfanview i see that only the red channel has been exported as greyscale targa

when i let the script print out ‘depth’ it’s 8, even directly after loading, before any changes are made

is this a blender bug or is there something i have to do?

blender 2.4rc1, full python 2.4, win xp

did anyone double-check this? should i post a bug?

  • 237 has the same problem

also the doc says there is an Image.New() method thats not in the current api
