Framebuffer is RGB565,Can I make a dynamic bitmap of ARGB8888?
I made one by cacheable container and display the dynamic bitmap by a texturemapper but the image came out is not correct,something did appear on screen,but size and color not right. but if I change bitmap type to rgb565,the image show correctly,but with black background and no alpha ,not what I wanted. There is enough cache,I confirm the dynamic bitmap is created successfully on both type.I tried to display the dynamic bitmap by a Image widget,but the result is the same.
In this forum,I can see a solution,to register a LCD32bpp class and set it as Auxiliary LCD in the hal.
But I didn't found any thread on this subject.
