How do you do this? I've gotten reports from users
that when they use color schemes on their Tungstens,
images that otherwise would have been transparent are
no longer working. I.e. the transparency color of the
bitmap is not the same as the background color.
Does the bitmap's background color vary for each color scheme? If it does NOT then most likely your bitmap is NOT transparent. I.e. it has fixed background color that only shows through when the color theme has a different background color.
If the bitmap background does vary with each theme then there may be an issue with your drawing code. Without knowing anything about your application I can only guess at what might be the cause. Are you copying the bitmap from an offscreen buffer, for instance?
If you make consistent use of UIColorTableEntries to set colors for gadgets and custom drawing operations then your application should work across all color themes. At least that's my experience.
