Linux/AM5728: Alpha blending formula used in DSS

Part Number: AM5728

Tool/software: Linux

Hello,

We are using AM 5728 PSDK 3.01.00.06.

Currently, I am trying to alpha blend with plane and BackGround.

DSS (SrcA * SrcC) + ((1 - SrcA) * DestC) I thought that I confirmed it by using alpha blending formula.

Currently we are writing with 2DGPU and 3DGPU Alpha blending uses (1 * SrcC) + ((1 - SrcA) * DestC).

I am experiencing difficulties in developing different methods used in DSS and methods used in GPU.DSS alpha blending
Do you change it like alpha blending used with 2D, 3D GPU?

Thank you.
