2015-11-12Clear decoders after the image decoder in the /Filter array.Oliver Chang
During decoding, when an image decoder is encountered, any subsequent decoders are ignored, but remain in the array. However, later on CPDF_DIBSource::ValidateDictParam expects the image decoder to be the last in the array, causing issues. A check is also added in CPDF_DIBSource::GetScanline to ensure that the calculated pitch value is <= the (4-aligned) pitch value in the cached bitmap to prevent future issues. Also cleans up some NULL usages. BUG=552046 R=jun_fang@foxitsoftware.com, tsepez@chromium.org Review URL: https://codereview.chromium.org/1406943005 .

2015-09-29Fix blank page issue caused by too strict correction on bpcchromium/2523Jun Fang
For bit per component (bpc), PDF spec mentions that a RunLengthDecode or DCTDecode filter shall always deliver 8-bit samples. However, some PDF files don't follow this rule. We can find that filter is RunLengthDecode but bpc is 1 in the provided test file. In this case, pdfium will correct bpc to 8 but the actual bpc is 1. It causes a failure because the data is much more than the expected. To handle this case, pdfium doesn't correct bpc to 8 when the original bpc is 1.

At one point in time, it may have made sense to indicate the expected alignment of the memory you're about to copy, but that was last century. The compiler will take care of it just fine.

2015-06-10Remove typdefs for pointer types in fx_system.h.Tom Sepez
This involves fixing some multiple variable per line declarations, as the textually-substituted "*" applies only to the first one. This involves moving some consts around following the substitution.

2015-03-16Fix a problem that JP2 image is not displayed because index color space is usedJUN FANG
There are two issues in this bug. One is that JP2 image is not displayed because it aborts loading Jpx bitmap when the number of components in color space is different with that one in JPX images. I found that the number of components in color space isn't updated after it's initialized. For index color space, the component shall inherit from its base color space. The second issue is that displayed color is not correct after I fixed the first issue. The root cause is that sRGB is used in JPX image, it doesn't need to map from index to RGB again.
