Michael Niedermayer	657878f76e	sws: fix copy case detection with gray8a. Fixes gray_alpha.png Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Paul B Mahol	0cc1a86dc3	rgb2rgb: rgb12to15() Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	13 years ago
Ronald S. Bultje	e7843db3df	swscale: fix invalid conversions and memory problems. Fixes problems where rgbToRgbWrapper() is called even though it doesn't support this particular conversion (e.g. converting from RGB444 to anything). Thirdly, fixes issues where rgbToRgbWrapper() is called for non-native endiannness conversions (e.g. RGB555BE on a LE system). Fourthly, fixes crashes when converting from e.g. monowhite to monowhite, which calls planarCopyWrapper() and overwrites/reads because n_bytes != n_pixels.	13 years ago

Janne Grunau	6e9bb5aa3e	swscale: prevent invalid writes in packed_16bpc_bswap Writes past the end of the destination buffer were occuring when its stride was smaller than the stride of the source. Fixes Bug #183.	13 years ago

John Stebbins	09d243ddd0	swscale: Fix stack alignment for SSE Although gcc guarantees 16 byte stack alignment, threads under WinXP don't appear to be guaranteed to start stack aligned. So fix the alignment. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	13 years ago

Kostya Shishkov	42ba12888b	Do not convert RGB buffer at once when stride does not fit exact samples. When converting RGB format to RGB format with the same bits per sample, unscaled path performs conversion on the whole buffer at once. For non-multiple-of-16 BGR24 to RGB24 conversion it means that padding at the end of line will be converted too. Since it may be of arbitrary length (e.g. 8 bytes), operating on the whole buffer produces obviously wrong results. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	14 years ago
Ronald S. Bultje	55eda370cb	swscale: clip unscaled colorspace conversion path. Prevents overflows on very bright scenes when adding dither, which may lead to black dots.	14 years ago

Ronald S. Bultje	1ce724ee39	swscale: implement error dithering in planarCopyWrapper. Based on a somewhat similar idea in FFmpeg's swscale.	14 years ago
Ronald S. Bultje	6af2801088	swscale: split swscale.c in unscaled and generic conversion routines. This duplicates the function fillPlane().	14 years ago
