2016-08-19Fix an embedder test with leaked page objectchromium/2836chromium/2835weili
The public API FPDFPage_New() incorrectly said to use FPDFPage_Delete() instead of FPDF_ClosePage() to free the new page. This led to a page object leak in an embedder test. Correct the public API description as well as its usage in the embedder test. BUG=pdfium:242 Review-Url: https://codereview.chromium.org/2260683003

2016-08-19Stub out Document::syncAnnotScan method.chromium/2834tonikitoo
The PDF specification [1] says: " syncAnnotScan guarantees that all annotations will be scanned by the time this method returns. (..) Normally a background task runs that examine every page and looks for annotations during idle times. " The statement details specifically how Acrobat implements this method. Although, neither the method itself nor the background scanner task are implemented in PDFium (as of today, Ago/2016), not having ::syncAnnotScan at least stubbed out can be considered harmfull since its absence makes JS acrobat scripts silently fail when it has a call to it. Given that, and following a stub-out pattern present in other methods including ::addAnnot and ::addField, CL provides a stubbed out implementation of Document::syncAnnotScan.

2016-08-18Add initial Document::getAnnot supportchromium/2833tonikitoo
CL implements the first step in order to support Annotations manipulation in PDFium: Document::getAnnot. The method takes two arguments, an integer (page number) and a string (annotation name). When called, it iterates over the annotations on the given page number, searching for the one whose name matches the string in the second parameter. If found, then an Annot instance (see Annot.cpp/g added by this CL), is bound to a Javascript object and returned. With the use cases described in bug [1] as an initial test case, CL adds support to the following Annotation object properties: - hidden - name - type Idea is to keep evolving the implementation with more methods and properties in follow up CLs.

2016-08-18Use a map for app::m_Timersdsinclair
Currently the timers is a vector. When we cancel a timer we have an O(n) operation to remove the timer. If there are a lot of timers (which this test has > 16k) this can take a long time. The impact is a lot lower in Release, but the test is very slow in Debug.

If the control is not found in the CPDF_InterForm control map then ::GetControlByDict can return nullptr. This nullptr was not handled in CPDFSDK_Widget::GetFormField().

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].

2016-08-15Only create widgets if really needed.dsinclair
Currently the GetWidget call will create a backing widget for a control behind the scenes if it doesn't exist. This can cause more work to be done then needed as we may need to create the page and any supporting structures. This created structure will then be torn down as we don't need it anymore once we're done with the widget. For the instances where setting the value on the widget will have no effect (as we'll destroy it anyway) we can tell GetWidget() to not create the widget and return without doing any work.

2016-08-15Move some v8 objects from CJS back into FXJStsepez
Create a new class to hold these, CFXJS_Engine (could have been called Runtime, but there are too many "Runtimes" already). In a subsequent patch, all the FXJS_*() functions that take an isolate as the first argument can become methods on the engine. CJS_ must still manage the isolates; this happens outside the engine. The IJS_Runtime abstraction moves up to fpdfsdk/javascript; it remains to allow for either a real JS library or a stubb one to be linked (for non-js builds).

2016-08-15add native draw bitmap with alpha maskcaryclark
PDFs draw bitmaps with alpha by supplying an image alpha mask along side the image color data. The alpha mask may not be the same scale as the image data. Skia doesn't have a direct mapping for this draw call, but can come close by using the internal SkCompositeShader class. This scales the alpha mask to match the size of the image data, then puts both in the composite shader to draw. There are more things to do: - Allow Alpha8 or Gray8 to draw scaled to a matching device (blit doesn't work today) Temporary code marked with a TODO implements this functionality. - Refactor PDFium to allow SkComposeShader's components to take a matrix. The latter goal will defer drawing so that PDFium doesn't resize the mask, discarding resolution, before Skia has a chance to record it. Additionally fix drawing text with a negative font size.
