Hi all,
I want to write a bitcount = 24bit(or 8bit) image to a tif file with JPEG compression. I can save it with photometric = PHOTOMETRIC_RGB,but when i save it with PHOTOMETRIC_YCBCR it seems doesn't work, why?
It seems that i should do some operations on the RGB source image before i save it with PHOTOMECTRIC_YCBCR?
do anyone have some similiar codes? or if there is something important i need to know to implement this feature?
thanks in advance.!
