--- Comment #1 from Neil Roberts <n...@linux.intel.com> 2012-02-25 17:44:51 PST --- Created attachment 57646 --> https://bugs.freedesktop.org/attachment.cgi?id=57646 readpix: Don't disable fast path for normalized types Mesa has a fast path for the generic fallback when using glReadPixels for RGBA data which uses memcpy. However it was really difficult to hit this case because it would not be used if any transferOps are enabled. Any type apart from floating point or non-normalized integer types (so any of the common types) would force enabling clamping so the fast path could not be used. This patch makes it ignore clamping when determining whether to use the fast path if the data type of the buffer is an unsigned normalized type because in that case clamping will not have any effect anyway. This patch additionally makes it explicitly ignore luminance types because in that case the conversion to and from RGB does not end up with exactly the same values. -- Configure bugmail: https://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug. _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/mesa-dev
