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
Nathan Adil Maxson	7b3894bee9	swscale: fix formatting and indentation of unscaled conversion routines. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	13 years ago
Janne Grunau	b4dc68803b	swscale: add endian conversion for RGB555 and RGB444 pixel formats Add a macro to shorten the if condition.	13 years ago
Janne Grunau	ed46a3d842	swscale: add rgb565 endianess conversion	13 years ago
Janne Grunau	72cb904453	swscale: add unscaled packed 16 bit per component endianess conversion	13 years ago
Ronald S. Bultje	185655c601	swscale: add support for planar RGB input.	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
Diego Biurrun	96c1e6d40d	doxygen: Make sure parameter names match between .c and .h files.	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
