Hey all, It seems when I Alphablend, I lost the color information and the image appears green. To be more specific, it''s the DrawWaveXAlpha function. I think the DrawWaveX works ok, but not this one. Am I doing something wrong?

i recommend Powerdraw instead of DelphiX for Alphablending (every kind) its much faster

DelphiX has a bit of an issue with the Alpha blending with videocards that support only 32,000 color 16-bit modes (it''s a 555 vs. 565 color storage issue)

The bug would be hard to fix because it sits in the funky ASM portions of DXRender.pas.

A workaround is to use 24 or 32 bit color modes...
