2016-09-20Assert that dictionary can own the objects it is given.tsepez
Upon indirect object holder destruction, all indirect objects are destroyed -- currently by order of increasing object number -- but ideally without ordering constraints. So currently, we can get away with a dictionary pointing directly at an indirect object with a higher number. It gets destroyed first, invoking Release() on its subordinates, which skips destroying them if they are indirect objects. But we don't want to rely on this artifact of destruction order. Should it happen to be reversed, the dictionary would invoke Release() on freed memory. Interestingly, CPDF_Array skirts the issue by replacing any indirect objects it is given with references. Not clear whether we should do the same thing for dictionaries, or remove it from arrays. The technique certainly complicates understanding ownership. The one violation found is in the unittest that broke the previous CL which tried to use unique_ptrs in indirect object holder. Review-Url: https://codereview.chromium.org/2353093002

2016-09-19Clean up CPDF_Stream.tsepez
Replace the CPDF_Stream(nullptr, 0, nullptr) pattern with a default ctor. Remove unused parameters from CPDF_Stream::SetData(). Both are always passed as FALSE. CPDF_Stream declared its own m_GenNum, which shadowed the one in CPDF_Object. It was used only to distinguish file/memory streams, so add a bool explicitly for this purpose. Remove the union, it would be sad if we confused user data with a C++ object with virtual function calls. Use unique_ptrs with appropriate deleters to manage memory.

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.

2016-09-12Remove 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
2016-09-08Check 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

2016-09-01Fix leaks due to created popup annotationschromium/2847weili
When we create popup annotations, we also create the dictionary associated with it. For regular annotations, the dictionary associated with an annotation is not owned by annotation, and will be released separately. But our created dictionary is not associated with any other data structure, it would be leaked if not released by the associated annotation. Add a boolean to indicate the ownership to the dictionary, and release the owned dictionary during the destruction of an annotation.

2016-08-24Lazy generate an "AP" when an Annot's hidden state changestonikitoo
Now that Document::getAnnot works and annotation instances can have its properties changed, consider the following scenario: - A PDF content has an annotation without AP and CPVT_GenerateAP is called to generate one. - However the annotation also has its hidden flag set (/F 2), and CPVT_GenerateAP bails out earlier, not generating an AP. - When the PDF's Javascript runs, it acquires an instance of this annotation object, bounded to JS using Document::getAnnot(), and set its "hidden" flag to false. - At this point, the annotation should get drawn, but it does not because its "AP" was never generated. CL fixes this scenario by making PDFium able to lazy generate APs, if needed. BUG=pdfium:492 Review-Url: https://codereview.chromium.org/2265313002

2016-08-16Hidden annotations should not be drawntonikitoo
Now that PDFium supports drawing of more annotation types, it should also respect the "hidden" flag that annotations might feature. For instance, in IE/Acroread if an annotation is flagged as "hidden" it does not get drawn. CL adds a check for the specific "hidden" flag, not drawing annotation that are flagged with it, in order to match IE + acrobat reader behavior. The "flags" definition can be seen by looking at "/F {value}" syntax in a PDF file source, where {value} is an predefined integer value. Test: PDF files being added in [1].
