2016-07-06copy graphics state fullycaryclark
The dash parameters where not copied; the copy could point at random data and cause corpus tests to hang when testing Skia. PDFium measures text directly by calling FreeType. Turn off hinting altogether in Skia so that drawn text matches the metrics that PDFium measures. Premultiply bits retrieved from images, and check to see that the device bits are always premultiplied. Look for null graphics state and matrices.

Take the requested font weight and italicization into account when searching for fonts. For example, for a font with the face "Arial" and a weight of 700, search to see if "Arial Bold" is available. BUG=530 Review-Url: https://codereview.chromium.org/2119983002

2016-06-29add local caching for skia drawscaryclark
PDFium assumes the lowest common denominator and draws many strings and paths that can be accumulated. Defer canvas->restore() calls until required because the clip changed. Defer text and path draws as long as subsequent calls concatenate additional data. Include debugging switch to allow disabling cache at compile-time while bugs are shaken out.

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
Check required hint table dictionary entries and make sure they: - Exist. - Are of the right type. Along the way: - Fix FX_atonum() to not have a non-const pass-by-ref param. - Simplify code in CPDF_StreamContentParser. - Make CPDF_Number::IsInteger() a const method.

2016-06-23Use some FXSYS methods instead of duplicatingdsinclair
This CL uses the FXSYS_isDecimalDigit in place of a few custom IsDigit methods. It also creates an iswspace and some fractional math helper methods to share some code. Review-Url: https://codereview.chromium.org/2094453004

2016-06-20Fixup LoadImageInfo type checking.dsinclair
The ::DetectImageType method does more then just detecting the image type, it also sets up various needed structures to handle the decoding. Instead of skipping the ::DetectImageType call this CL changes the code to return early if the image check fails. This should allow us to stop working on images which do not match the required data format. BUG=chromium:621094 Review-Url: https://codereview.chromium.org/2085493002
