Hello,
I need help with bitmaps as my tests results in unexpected/random behavior.
I need to get current glyph from a BitBtn, clone it to another bitmap (to be stored in memory), then process the image content and finally write the result to the BitBtn.
In my tests I clone the bitmap using TBitmap.RawImage and everything looks to work fine but after setting BitBtn.Glyph to this new created bitmap sometimes the operation works fine (when mouse is over the BitBtn), other times it simply disappear and other times it is partially painted blending new content with old one.
Just for the test I was using .ico file with transparency (32 bits), other formats will be supported later, but now I need at least one format that works fine.
Platform is Win32 running Windows 7. I hope to handle it in a cross platform way, or even specific code for each platform.
Is there any recommended operations sequence ? Forget about TBitmap and use TLazIntfImage ?
Thank you.
