I am using Flexcolor driver with 16-bit color resolution and precompiled EMWin library for ARM MDK.
Memory is limited, so no cache is used. Display controller is ILI9341. I am curious if it is possible to
use bitmaps with transparent background? If so, which format should be used for conversion to C
source file?
In BMP2C converter, I convert image to best palette+transparency, select 0x00000000 as transparent color
and then export to C file but after that, transparency is lost and image is shown with black background.
I have implemented display read-back function and it seems to work correctly ( I can see GUI reading
back pixel data in chunks of 3 bytes).
Icons are stored in PNG format and have transparent background (sample attached).
