* DMA2D_BLEND_NONE:
|

* Informs the driver to disable all blend operation for the given layer.
|
|
|
|
* That means the layer is opaque.
|
|
|
|
*
|
|
|
|
* DMA2D_BLEND_ALPHA:
|
|
|
|
* Informs the driver to enable alpha blending for the given layer.
|
|
|
|
*
|
|
|
|
* DMA2D_BLEND_PIXELALPHA:
|
|
|
|
* Informs the driver to use the pixel alpha value of the layer instead
|
|
|
|
* the constant alpha value. This is only useful for ARGB8888
|
