RGBTRIPLE Structure, i.e., it is not a simple data type. RGBA (Red-Green-Blue-Alpha) takes the same space as an Int32/DWORD/COLORREF, but COLORREF can actually be casted as a RGBA structure.

> say for example 8-bit is for the char and 32-bit for int, so what is for 24-bit for the GDI

FASM doesn't have "char" (of unknown signedness) nor "int" (of unknown size") Laughing

RGBA or RGBU Smile

The dilemma of 24bpp (saves memory but alignment horror) vs 32bpp (wastes memory but alignment is fine)

32bpp only wastes space if you don't use alpha Smile
