Now all clear, understand.
In italian " come il cacio sui maccheroni ", i am starting to modify some bmp gauges both for italian and japanese cockpits, but i have a problem.
For the gauges without trasparency all ok , with trasparency part i have try with the black color, with the transparent backgrouns, from 16,7 million color 24 bit to 256 colors 8 bit, but nothing the part that will be invisible or is white or is black.
Any help please? Probably is very simple but i can't find the solution.
Best regards.
