HI,
I port emWin to stm32f769, use DSI cmd model .
I need to use image with alpha , it can be ARGB565 or ARGB4444，
the problem is , emWin supports ARGB565, not support ARGB4444,
and the LTDC supports ARGB444 , not support ARGB565.

BUT THE LTDC SIDE
LCDConf.c
/* Define the possible color modes */
#define CMS_ARGB8888 1
#define CMS_RGB888 2
#define CMS_RGB565 3
#define CMS_ARGB1555 4
#define CMS_ARGB4444 5
#define CMS_L8 6
#define CMS_AL44 7
#define CMS_AL88 8
can anyone give me some advice how to deal with it?
