CoreGraphics doesn't support RGB565 natively. You'll need to create your bitmap context with a different format and then convert to RGB565 using something like vImageConvert_ARGB8888toRGB565
.
CGBitmapContextCreate bitsPerComponent for RBG565

سؤال
I'm trying to create a CGContextRef
using CGBitmapContextCreate
. The bitmap I want to create is RBG565 (red and blue are 5 bits, green is 6 bits). One of the parameters for CGBitmapContextCreate
is bitsPerComponent
. Since I have variable bitsPerComponent
, I'm not sure if I just set it as 5, or is there a better way to do it?
Thanks.
