2016-08-15Push v8::Isolate into CFXJS_Engine classchromium/2831tsepez
Nearly all the "loose" functions in FXJS become methods on the CFJXS_Engine. This is the "missing link" wrt some layering violatons that have been around forever. We can stop passing &m_ variables from CJS_ down into FXJS Initialization as a result. Review-Url: https://codereview.chromium.org/2245863002

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).

2016-08-15Fix CGdiPrinterDriver::DrawDeviceText() to draw multiple characters.thestig

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.

2016-08-11Relax a check in CPDF_HintTables.thestig
CPDF_HintTables::ReadSharedObjHintTable() unnecessarily constraints a FX_FILESIZE value to an int32_t.

Bad values in |m_szSharedObjOffsetArray| will still cause hint table loading to eventually fail. BUG=635565 Review-Url: https://codereview.chromium.org/2230883003

CPDFSDK_ActionHandler are unclear. It does not add encapsulation, nor simplicity to the logic. CL is a driven-by clean up that merges CPDFSDK_FormActionHandler into CPDFSDK_ActionHandler. It takes the opportunity to delete CPDFSDK_ActionHandler (now) empty constructor and destructor, in favor of compiler-generated ones. No behavior change is expected, so no new tests are being added.

2016-08-08Add support to Document::gotoNamedDest method.tonikitoo
Patch implements the Document's API gotoNamedDest, which is part of the PDF specification [1], page 129, with the following (short) description: "Use this method to go to a named destination within the PDF document". [1] http://partners.adobe.com/public/developer/en/acrobat/sdk/5186AcroJS.pdf "Named destination" is a common concept in the PDF world. It can be used together with PDF's Links, Annotations, Bookmarks and OpenActions, as well as an action per se, in case "this.gotoNamedDest" is called directly. Note that the implementation makes use of the existing hook CPDFDoc_Environment::FFI_DoGoToAction, which ends up calling out the embedder to actually handle it. In case of Chromium, for instance, it calls PDFiumEngine::Form_DoGoToAction which only handles for now the "page" property of the "destination". Other properties, including zoom level, and scroll position are ignored for the moment. BUG=pdfium:492 Review-Url: https://codereview.chromium.org/2221823003

The CJS_Timer is fairly far removed from JS itself, the wrapper objects are CJS_TimerObj and TimerObj. Make it sound less like them. Having moved the code to app.cpp, the GlobalTimer can now refer directly to the app, rather than its superclass of CJS_EmbedObj.
