Photo Studio - Alpha channel??


New member

Any one who knows how to make the alpha channel work in Photo Studio when saving as TIF?? The documentation says TIF-files should come with a alpha channel, and I find one when I open the TIF in photoshop, but it's all white and has no outline/contour.

Extract from Catia documentation:
Images rendered in .tif format can easily be used for compositing thanks to alpha channel support. Alpha channel determines the opacity level of the pixel and is used for generating graphic effects when overlaying two bitmaps. Image pixels that do not cover any geometrical object have a transparent alpha channel, thus allowing to nicely embed the rendered image in any other image used as background.
