	3179	Graphic Utility Library	Bug Report	Low	TIFFReadRGBAImageOriented Premultiplication rounding er...	New	Win32	0%		Task Description TIFFReadRGBAImageOriented executes an alpha premultiplication even when the alpha value is stored as EXTRASAMPLE_UNASSALPHA. This leads to rounding errors. example: (correct mathematical rounding) gt: 226 and alpha 0.5 -> 127 read the premultiplied value: 226127/255 = 112.56 -> 113 converting to nonpremultiplied value: 113255/127 = 226.89 -> 227 gt: 225 and alpha 0.5 -> 127 read the premultiplied value: 225127/255 = 112.06 -> 112 converting to nonpremultiplied value: 112255/127 = 224.88 -> 225 so we have a difference of 1 or 0 between the ground truth and the read value after undoing the premultiplication. (incorrect mathematical rounding) gt: 226 and alpha 0.5 -> 127 read the premultiplied value: 226127/255 = 112.56 -> 112 converting to nonpremultiplied value: 112255/127 = 224.88 -> 224 so incorrect mathematical rounding leading to much worse results. Consider using a different way to read the tiff image (for instance ReadEncodedStrip).
