2016-07-28fix text matrix againcaryclark
The text matrix for Skia is still wrong. The last fix allowed text to draw correctly when rotated, but did not draw correctly when skewed. With this edit, text draws correctly rotated, skewed horizontally, skewed vertically, and rotated and skewed. R=dsinclair@chromium.org Review-Url: https://codereview.chromium.org/2189093002
2016-07-27Fixup integer conversion logic.chromium/2813chromium/2812chromium/2811dsinclair
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.

2016-07-27Splitting fx_ge_fontmap.cppnpm
Move CFX_FolderFontInfo, CFX_FontMgr, and CFX_FontMapper into their own classes. There are namespaces in each of the new files, having methods from the original namespace in fx_ge_fontmap, according to what each class needs. Review-Url: https://codereview.chromium.org/2185533006

2016-07-15Use CPDF_Dictionary::SetAtReference instead of CPDF_Dictionary::AddReference.jaepark
The definitions of CPDF_Dictionary::SetAtReference and CPDF_Dictionary::AddReference are identical, and AddReference is only used once. So remove CPDF_Dictionary::AddReference method and use CPDF_Dictionary::SetAtReference instead. Review-Url: https://codereview.chromium.org/2161453002

2016-07-07set font cache if nullcaryclark
testing/corpus/fx/path/path_10_jd.pdf sets the document to null. (It can't be read at all by MacOS Preview.) This causes the font cache to also be null. In this case, get the font cache from CFX_GEModule instead. R=dsinclair@chromium.org Review-Url: https://codereview.chromium.org/2128043004

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.

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.

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
