I want to give a layer gradual transparency using the alpha plane
feature of the Fujitsu coral graphics controller.
The Coral spec says, layer 5 can be used as the ‘blend coefficient
layer’ in PAL8 mode. Unfortunately I can’t find any way in the QNX layer
API to use this ‘alpha plane mode’. IMHO there should be at least one
Pg_LAYER_*_PIXEL_ALPHA flag in alpha_caps set when requesting the
available layer capabilities of l5 in PAL8 mode.
Any suggestions or code snippets to get this to work?
Is layer x in coral spec terminology == layer x in QNX API terminology?
(it doesn’t fit the YUV feature, in spec l1 can have YUV on target l4 is
told to have YUV - quite confusing)
