Ok I have the problem that the the code is not showing the icon correct in the colorspace B_RGBA32 mode but it works with B_CMAP8 So first question is what I did make wrong inside the code (may I missed some option for the Drawing settings) or is this a bug in Haiku (I know that B_RGA32 for SetBits is not supported under BeOS). Next question is, how I can convert my bitmap source bits from 32bit with B_RGBA32 colorspace to 16bit with B_CMAP8. Thanks for the reply -- Joerg Meyer <mailto://joerg.meyer@xxxxxxxxx>
