2016-08-30[Merge to M53] Fixup integer conversion logic.chromium/2785Dan Sinclair
In bc8a64029f898286c3dcad3a6cecdc98ef30b139 we updated the FX_atonum logic to correctly handle integer overflow. This causes issues when parsing the Permissions flag of encrypted documents as that flag isn't encoded like other numbers. The Permissions flag is a unsigned value, and has to be treated as such since the sign bit is always set. The current logic will detect an overflow of the int value and return 0. The old logic would have detected the overflow and returned the negative result regardless. This CL updates the logic to do the string to int conversion as a uint32_t and then verifies the uint32_t value, if a sign was provided, fits within the int range, otherwise it converts it to an int and lets it be positive or negative as needed. Merge clean TBRing.

2016-06-27Double AdobeCMYK_to_sRGB speed with faster roundingbrucedawson
FXSYS_round is painfully slow on Windows. It does range checking and then calls an extremely expensive function. It ends up consuming half the CPU time when decoding the images in PDFs such as this one: https://www.ets.org/Media/Tests/GRE/pdf/gre_research_validity_data.pdf SSE can be used to optimize this: __m128 cmyk = {c * 255, m * 255, y * 255, k * 255}; uint32_t output[4]; _mm_storeu_si128((__m128i*)output, _mm_cvtps_epi32(cmyk)); but is cryptic, only works for x86/x64, and gives basically identical performance to this solution - int(c * 255 + 0.5f); The rounding behavior is not identical but in practice this rarely matters, and in this specific case it does not matter because the edge cases that vary are not hit. The three divisions at the end were changed to multiplies because profiling showed they were a significant cost. This change reduces the image-decode stalls in the PDF listed above by about 40%, making for a noticeably better experience. Further optimizations are possible but would require significantly more time and testing. BUG=617365 Review-Url: https://codereview.chromium.org/2096723003
2016-06-23Improve hint table validation checks.thestig

The ::DetectImageType method does more then just detecting the image type, it also sets up various needed structures to handle the decoding.
