Hi,
What is the most efficient call to NanoX in order to copy/display a raw bitmap, that has not been generated by Nano-X ?
Would it be better to use "GrArea" or "GrDrawImageBits" ?
Does the answer depend on the bpp of the image and/or the screen device ?
I would also suggest to add a sanity check [maybe optional if the performances are critical] in GrArea on the "width" value: if this value is zero, Nano-X crashed with a FPU exception (divide by zero, indeed).
Thanks,
Emmanuel.
