I am trying to make a semi-transparent bitmap that essentially darkens a portion of my gauge. I have used the rectangle and set the opacity, that works, but I need an unusual shape. I have tried applying a mask to the rectangle, and you lose the ability for opacity then. So now I have been trying to figure out the proprietary bmp-with-alpha that FSX uses. I have gotten some results, but whenever I have semi-transparent black in Photoshop, then use imagetool to convert it, I end up with a shade of gray.
I think I am on the correct path, just missing a crucial step. Are there any tutorials on this subject, I can only seem to find tutorials on repaints and scenery, nothing for gauge artwork.
