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 Beginning with PDF 1.5, this entry is obsolete and should be ignored."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
2016-09-12Verify value of prec before usingdsinclair
The fx_codec_jpx_opj code will attempt to do a 1 << (prec - 1). If the prec value is >=32 then that shift will overflow the int value. This CL adds a check that prec is < 32 before attempting the shift. BUG=chromium:633208 Review-Url: https://codereview.chromium.org/2334823002

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
2016-09-08Fix memory management errors for font loading and copyingweili
A few issues are fixed: --Change variable |m_bLogic| in CFX_Font to |m_bShallowCopy| to reflect its meaning better; --For a shallow copy of font, we must guarantee that the copied font will not be deleted until the shallow copy is deleted. So need to increase the src font's refcount when copying it; --The stream |m_pOwnedStream| needs to have matched new/delete These errors need to be fixed before we can properly delete all the fonts to address the leaks. BUG=pdfium:242 Review-Url: https://codereview.chromium.org/2322043002
2016-09-08Pass CFX_WideString further down widget callerstsepez
Avoid a couple of places where we copy the raw string back into a brand-new widestring. There are a few places where the difference between a null ptr and an empty string control the logic, and I left these as-is. Other places can just take the string by const ref.

2016-09-08Replace CJS_Runtime::Observer with CFX_Runtime<CJS_Runtime>::Observertsepez

Two leak cases are addressed here: --In CFGAS_FontMgrImp::LoadFont(), calling LoadFace() is unnecessary since the following LoadFile() does the exact same thing. Calling LoadFace() without releasing the loaded face results in a leak; --|m_Hash2Fonts| in class CFGAS_FontMgrImp owns all the fonts stored in it.

2016-09-07Add observer for BAAnnots from Javascriptdsinclair
This Cl moves the observer code from the CPDFSDK_Widget up into the CPDFSDK_Annot base class and then adds a second observer for CPDFSDK_BAAnnot objects. This allows us to attach an observer to the Annot javascript class which will update its internal pointer to the BAAnnot if the BAAnnot is destroyed by the CPDFSDK_PageView being destroyed.

2016-09-06Do not re-create the page view when accessing from Document::removeField.dsinclair
When removing a field from the document we can force the recreation of a CPDFSDK_PageView by passing |true| as the last parameter to |GetPageView|. This will force a new page view to be created so we can delete a field from it and, we then end up with a dangling PageView. This CL passes |false| to |GetPageView| and skips removing the widget if we do not receive a pageView back from the document.
