uint32_t DMA2D_LayerCfgTypeDef::InputAlpha

Specifies the DMA2D foreground or background alpha value and color value in case of A8 or A4 color mode. This parameter must be a number between Min_Data = 0x00 and Max_Data = 0xFF except for the color modes detailed below.

Note:

In case of A8 or A4 color mode (ARGB), this parameter must be a number between Min_Data = 0x00000000 and Max_Data = 0xFFFFFFFF where

• InputAlpha[24:31] is the alpha value ALPHA[0:7]
• InputAlpha[16:23] is the red value RED[0:7]
• InputAlpha[8:15] is the green value GREEN[0:7]
• InputAlpha[0:7] is the blue value BLUE[0:7].
