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. BUG=610555 Review-Url: https://codereview.chromium.org/2095763003
2016-06-23Remove FPDFAPI_LoadCID2UnicodeMap.dsinclair
This Cl removes FPDFAPI_LoadCID2UnicodeMap() and inlines the code into the one caller. Review-Url: https://codereview.chromium.org/2097513002
2016-06-22Fix memory leaks in EmbedderTest::OpenDocument().thestig
EmbedderTest::OpenDocument() does not gracefully handle the case of being called twice in a given test case. So avoid doing that. Review-Url: https://codereview.chromium.org/2088093002
2016-06-21Use FXFONT defines in place of integers.thestig
Fix nits along the way. Review-Url: https://codereview.chromium.org/2083943003
2016-06-21Move ifx_renderdevicedriver to a separate file to shareweili
Move ifx_renderdevicedriver class to its own file to share with multiple devices to reduce code duplication. Review-Url: https://codereview.chromium.org/2078783002
2016-06-20Change func(void) to func()weili
Since PDFium is compiled as C++ code, the void keyword is not needed. BUG=pdfium:519 Review-Url: https://codereview.chromium.org/2084603003
2016-06-20Another round of fx_ge cleanup.thestig
- Clean up CFX_GEModule. - Remove duplicate #defines in fx_ge.h - Remove IsFontStyleFromCharCode() that always returns true. - Mark a FXTEXT_CHARPOS field as Mac only. Review-Url: https://codereview.chromium.org/2075333002

2016-06-13Make code compile with clang_use_chrome_plugin (part I)weili
This change contains files in core/fpdfapi directory. This is part of the efforts to make PDFium code compilable by Clang chromium style plugins. The changes are mainly the following: -- move inline constructor/destructor of complex class/struct out-of-line; -- add constructor/destructor of complex class/struct if not explicitly defined; -- add explicit out-of-line copy constructor when needed; -- move inline virtual functions out-of-line; -- Properly mark virtual functions with 'override'; -- some minor cleanups; BUG=pdfium:469 Review-Url: https://codereview.chromium.org/2060973002
2016-06-08Remove even more const casting from core.tsepez
Make the return types/arguments match reality. Review-Url: https://codereview.chromium.org/2053483002
2016-06-08Set data availablity error.dsinclair
If we have been told we have a hint table, but fail to read the table, set the document status to error instead of just returning. BUG=pdfium:512 Review-Url: https://codereview.chromium.org/2040373003
2016-06-08Remove implicit CFX_CountedRef::operator T*()tsepez
Explicitly invoke GetObject() method instead. This avoids having code where it looks like non-pointers are assigned to pointers but works due to the cast operator. Review-Url: https://codereview.chromium.org/2045083003
2016-06-07Avoid const-cast in CPDF_Fonttsepez
Introduce a logically const initialization (via mutable members) so that this can happen lazily under const methods. Review-Url: https://codereview.chromium.org/2045033002
2016-06-07Use static_casts for cpdf_type1font bsearch on mac.tsepez

2016-06-07Check the hint table exists before using.dsinclair
It's possible for the hint table to not exist event though we have a hint key in the object database. If the table does not exist then return false from CheckHIntTables(). BUG=pdfium:512 Review-Url: https://codereview.chromium.org/2047723002

2016-06-03Fix more bugs found by /analyze toolweili
Three more bugs are discovered: -- potientially used freed pointer; -- potientially used uninitialized variable; -- Used '&&' instead of bitwise operator '&' BUG=chromium:613623, chromium:427616 Review-Url: https://codereview.chromium.org/2040503002
2016-06-03Fix some code which causes warnings when compiled by /analyze toolweili
The code may not cause error conditions, but can be improved. These warnings include uninitialized variables, signed/unsigned mismatch, redundant condition, and using bool in arithmetic operations. Also remove a chunk of unused code. BUG=chromium:613623, chromium:427616 Review-Url: https://codereview.chromium.org/2036203004
2016-06-02Fix all the code which has duplicate variable declarationsweili
When there are duplicate variable declarations, the inner names shadow the outter ones. This is error prone and harder to read. Remove all the instances found by /analyze. BUG=chromium:613623, chromium:427616 Review-Url: https://codereview.chromium.org/2027273002
2016-06-02The PDFium source in core/fxge/dib implements a bit-blitting backend.caryclark
This code has several disadvantages over a more modern graphics engine: - no SIMD support - no GPU support - limited quality Further, calling this code locks in the perceived resolution, so that the output cannot be scaled without additional loss. By directing all bitmap drawing through CFX_SkiaDeviceDriver::StartDIBits, Skia can handle all appropriate bitmap optimizations. To that end, SetDIBits and StretchDIBits now call StartDIBits. Other changes: Skia's bitmaps are premultiplied. PDF contains bitmaps that are unpremultiplied. PDFium appears to use premultiplied bitmaps sometimes, and unpremultiplied bitmaps elsewhere. Add a debug check for unpremultiplied bits in Skia's driver, and add a utility to premultiply PDFium's bitmaps' bits. PDFium supports a 24 bit RGB bitmap padded to a 32 bit word. Set the high byte so that Skia can treat this as an ARGB bitmap. Defer the application of the alpha value to the draw call rather than calling MultiplyAlpha where possible. Allow the destination bitmap to be alpha 8 or argb 32. Review-Url: https://codereview.chromium.org/2025043002
2016-06-01Change CFX_Font::GetPsName() to return a CFX_ByteString.thestig
So everyone can avoid doing Byte to WideString conversions. Also remove CFX_GEFont::GetPsName() and deduplicate a couple of GetPsName() calls. Review-Url: https://codereview.chromium.org/2019173002

2016-05-25Remove CFX_PrivateData from CPDF_Documenttsepez
Replace it with two generic slots for Links and Codec usage. Since the codec is at a lower layer than the document, we don't provide separate get/set methods, since having a document upon which to call these would be a layering violation. Do the same for the Links for simplicity. Review-Url: https://codereview.chromium.org/2005193003
2016-05-25Remove CFX_PrivateData from CPDF_Pagetsepez
CFX_PrivateData served two purposes here: The first was to hold an opaque pointer to the corresponding page structure in the next higher layer, of which it knows no details. Introduce an empty CPDF_Page::View class to represent this higher class, so as to get type safety while preserving layering. The second was to hold an opaque render context, which it also happened to own. Make this a CFX_Deletable to help with management. Also remove an unused inheritance from CFX_PrivateData in CPDF_Annot. Review-Url: https://codereview.chromium.org/2008553008

2016-05-24Remove CFX_PrivateData from CPDF_ModuleMgrtsepez
Its only used to store one object, so replace it with a unique_ptr to a class with a virtual dtor. Rename the prototypical class with virtual dtor from CFX_DestructObject to CFX_Deletable. Rename the fx_basic_module.cpp to cfx_modulemgr.cpp to match the one class in it. Review-Url: https://codereview.chromium.org/2013483003
