* Don't crash when BMP color table is brokenHarald Fernengel2011-02-041-0/+2
| | | | | | | | | | If the BMP's number of color table entries is out of bounds, we would resize our color table vector to a silly value, leading to crashes later on. If the number of color table entries is larger than 256, just stop processing the BMP since it's most probably corrupt. Task-number: QT-4534 Reviewed-by: Robert Griebl

* Avoid in-place convertion of images with multiple referencesBenjamin Poulain2010-10-081-0/+4
| | | | | | | | | | | | | | | | The decoding from image reader was assuming the image reader do not keep the image internally. This is not true for the GIF plugins because the previous image can be used to compose the current image. This was causing crash on ARM because the 16 bits color depth causes the image memory to be reduce by half. When the plugin was accessing the memory, it assumes the images has not changed and is on 32 bits. This patch disable the in-place conversion if a detach is required. Regular conversion is the correct solution in this case, and it can also be made faster by converting while copying. Reviewed-by: Andreas Kling

The patch implement the conversion with SSSE3. This reduce by 3 the number of instructions, pushing the bottleneck to memory bandwidth. On Atom N450, the new benchmark is 40% faster for scanlines of 2000 pixels, 30% faster for scanlines of 32 pixels, and 15% slower for small images (3 and 8px). Reviewed-by: Olivier Goffart
