2016-09-19Remove duplicated charset definitions, and move them to fx_font.hnpm
PWL_FontMap does not need its own charset definitions. fx_edit.h does not need to define DEFAULT_CHARSET. XFA have their own definitions. They look different in that most are MAC or MSWin charset definitions. So they are left untouched. public/fpdf_sysfontinfo.h duplicate ones were left untouched due to being in public folder.

2016-09-15Use either /RECT or /QuadPoints for annotation coordinates, depending on /APtonikitoo
On Acrobat, if "/AP" is present on a text markup definition, the coordinates used to draw the annotation come from "/Rect values, whereas if "/AP" is not defined, the array defined in /QuadPoints is used to grab the annotation coordinates from. PDFium, on the other hand, uses "/Rect" regardless of presence or absence of "/AP". CL fixes PDFium to work similarly to Acrobat, in this case.

2016-09-15Use ToUnicode mapping even when unicode is 0.npm
CPDF_Font::UnicodeFromCharcode returns 0 only if ToUnicode map maps the charcode to 0. CPDF_SimpleFont::UnicodeFromCharcode and CPDF_CID_Font:: UnicodeFromCharCode return 0 only if the call to CPDF_Font returns 0. In other cases, these methods return an empty string. So when processing text, a 0 return from the method should not be replaced with the charcode. BUG=pdfium:583 Review-Url: https://codereview.chromium.org/2342073002

CFX_FaceCache::LookUpGlyphBitMap should remember its unsuccessful glyph bitmap calculations.

2016-09-14Split CPDFXFA_Document apartdsinclair
[DO NOT COMMIT] This CL renames IXFA_DocProvider to IXFA_DocEnvironment to better describe the purpose. Then, CPDFXFA_Document has all of the IXFA_DocEnvironment methods removed and placed in CPDFXFA_DocEnvironment. The CPDFXFA_Document then has a CPDFXFA_DocEnvironment. This splits the code related to the document apart from the XFA callback methods to work with that document. Review-Url: https://codereview.chromium.org/2328573002

2016-09-12Fix some leaks associated with memory allocatorchromium/2859weili
Use CFX_DefStore to only replace CFX_FixedStore, but not CFX_StaticStore, since CFX_StaticStore has different behaviors. CFX_StaticStore doesn't require its users to explicitly call free(), it frees all the allocated memory during destruction. Use CFX_DefStore to replace CFX_StaticStore would cause leaks. Also remove two undeclared, but defined, functions. BUG=pdfium:242 Review-Url: https://codereview.chromium.org/2328403002
2016-09-12Fix leaked value object in NamedPropertySetterCallback()weili

2016-09-12Remove GetDictBy("DR") from annot/field dictionariesnpm
We should not use DR field from annotation/field dictionaries, since these are not supposed to have one. In PDF spec 1.7, DR is defined only for the form dictionary, in 8.6.1. In addition, note 118 in Appendix H says "In PDF 1.2, an additional entry in the field dictionary, DR, was defined but was never implemented. Beginning with PDF 1.5, this entry is obsolete and should be ignored." The changes in CBA_FontMap fix the bug below. The changes in cpvt_generateap do not affect the bug but follow the reasoning from the above paragraph. BUG=pdfium:538 Review-Url: https://codereview.chromium.org/2337673002

2016-09-09Define behaviors of FPDF_RenderPageBitmap_Retail and FPDF_FFLDraw.chromium/2858chromium/2857chromium/2856jaepark
Previously, PDFium only supported widget annotations to draw forms. As we've implemented other annotations, the behavior of FPDF_RenderPageBitmap_Retail and FPDF_FFLDraw changed. So, this CL clearly defines what needs to be done in FPDF_RenderPageBitmap_Retail and FPDF_FFLDraw. This CL first assumes that PDFium users will always call FPDF_RenderPageBitmap_Retail and FPDF_FFLDraw to render PDF pages, because otherwise they are not able to support PDF forms. FPDF_RenderPageBitmap_Retail should only deal with non-widget annotations, such as highlight, underline, text, etc. If FPDF_ANNOT flag is passed, non-widget annotations are drawn. Otherwise, they are hidden. FPDF_FFLDraw should only deal with annotations that requires user-interaction, such as widget annotations and popup annotation. Since popup annotation is associated with non-widget annotation, they should not be drawn if the associated annotation is hidden. Thus, if FPDF_ANNOT flag is passed, popup annotations are drawn. Otherwise, they are hidden. Widget annotations should be always drawn regardless of FPDF_ANNOT flag since they need to be always displayed for PDF forms. Also, roll DEPS for testing/corpus to 8485b30. BUG=pdfium:594 Review-Url: https://codereview.chromium.org/2323203002

2016-09-08Reland of Fix leaked internal fontweili
Reland of Fix leaked internal font (patchset #2 id:60001 of https://codereview.chromium.org/2297303004/ ) In CFGAS_FontMgrImp::LoadFont(), a new internal font is created which is never released. It needs to be correctly marked as internal font to be released. Fix this by adding a new method to take the ownership of the font and mark it as internal font properly. The previous revert was caused by memory management errors which were fixed at https://codereview.chromium.org/2322043002/ BUG=pdfium:242 Review-Url: https://codereview.chromium.org/2320213002

In https://pdfium.googlesource.com/pdfium/+/461eeafe191068ac8c32f2717907fc6a22a667d2 we moved the map cleanup for the page view to happen before the page view was destroyed and before we killed the annotation focus. The map removal must happen before the pageview is destroyed, but must happen after we've killed the annotation focus in order to not create duplicate page views which point to the same page.

2016-09-08Check whether the annotation content is empty using CFX_WideString.jaepark
CFX_ByteString cannot properly check whether the contents string is empty because the first two bytes of text strings encoded in Unicode are always ASCII 254 followed by 255. So if we get contents in CFX_ByteString, the length will always be 2. Also, roll DEPS for testing/corpus to 608bf04. Review-Url: https://codereview.chromium.org/2293403003
