AlphaBlend function in cross platform LCL

Hi All
What is the analog of Win32 function AlphaBlend in cross platform LCL?
I need to draw TBitmap on Canvas with specified level of transparency.

I don't think there is a single command to draw bitmap with specified level of transparency. Perhaps you can try BGRABitmap package.
This how to make a transparent form with BGRABitmap discussion maybe can help you:
https://forum.lazarus.freepascal.org/index.php/topic,34038.msg222021.html
And this is a list BGRABitmap's tutorials:
