Transparent background?

[ssharlin]

Hi, is there a way to save images with a transparent background?

Also, are atom colors fixed?

Yes, for that very reason it saves in the tiff-file format. iRASPA uses RGBA-colors. You will need to change the background color and set the opacity to zero.

Yes, the atom colors can be changed, see the help/manual.
