2015-11-16Reland "Cleanup some numeric code.""chromium/2567Dan Sinclair
This reverts commit 0569ab0b11b723d9bca4ddd642b0cf8828c4bdd1. This changes the various comparisons of char >= '0' && char <= '9' and char < '0' || char > '9' to use std::isdigit checks. It also cleans up a handful of hex to digit conversions to call one common method. R=tsepez@chromium.org Review URL: https://codereview.chromium.org/1449873003 .

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 .

The state '12' is only used once. This CL folds the contents of state 12 back into the place where we set our state to 12. This works because all state 12 does is decrement the loop counter so we process the same character again and move us to state 0.

2015-10-28Check if document was opened during testing.Dan Sinclair
When we call OpenDocument we fail to check if the document was actually opened. Currently we return true in all cases (assuming we read the file). This CL updates the code to check if the document was opened and return false if not. I've updated several tests to check for FALSE instead of TRUE.

2015-10-26Revert "Make m_pShadingObj a CPDF_Stream instead of CPDF_Object."Dan Sinclair
There appear to be a bunch of corpus tests which fail with this change such as FAILURE: shading1.pdf This reverts commit 85361b227ad6786d2aeef8409b79a8d077a26ee9. Make m_pShadingObj a CPDF_Stream instead of CPDF_Object. This object is required to be a stream and was being converted as such. With the new type checking this caused us to pass a nullptr where previously we'd have, incorrectly, cast a CPDF_Dictionary to a CPDF_Stream. This CL changes the m_pShadingObj to always be a CPDF_Stream. Then, we never go down the bad code path because we check if m_pShadingObj is nullptr earlier and bail out.
