: I am trying to display JPEG images with Nano-X version 0.9 . When I use
: GrDrawImageToFit() to draw a *.jpg - image it is displayed, BUT it is
: dithered (unwanted effect). My screen device has 16 bpp, and PNG images
: are displayed nicely without dithering.
Look at the jpeg image loader engine/image_jpeg.c and change
the FASTJPEG (or similar) define near the top of the file. I think
this used to default to 1 which caused dithering, but worked on
all systems.

Greg
