2018-07-28Add CPDSDK_Annot::AsBAAnnot() checked downcast methodTom Sepez
XFA introduces some additional subclasses, so it doesn't hurt to be sure in all cases before making a static cast.

2018-01-12Use enum for tracking form field typesRyan Harrison
Within PDFium use enum class for better type safety when working with form field types. These values will still be converted to ints as part of the public API, since that is the existing API. This work is preperation for extending the number of form field types to have more specific entries for XFA.

2017-10-18Refactor HasXFAField into HasFormInfoRyan Harrison
The existing API is too restrictive for collection the metrics information that we want. Specifically it only tells us if there are XFA forms in the document, but not AcroForms. This refactoring makes the method more general, so that non-XFA information is provided also. This change in semantics of the return value required some changes at the call sites of the API.

2017-10-17Convert XFA Doc Types to be more preciseRyan Harrison
The existing types are PDF, Dynamic & Static, which are poorly named since they don't really convey the fundamental differences between the types. "PDF" is confusing because PDFium only handles PDFs, and "Dynamic" & "Static" describe what a form may do, not how it is specified or some other fundamental difference. The terms "Dynamic" and "Static" were especially confusing, since XFAF documents must be static by definition, whereas full XFA documents can be either dynamic or static, depending on whether or not they change their layout. The types have been renamed to be clear that they are talking about the type of PDF document being described. "PDF" becomes "None", since this is used to indicate that there are no XFA forms in the document. "Dynamic" becomes "Full", since this indicates that the entire XFA spec is being used for the forms, specifically display layout is in the XML. "Static" has become "ForegroundOnly", since the form is specified using the XFAF (XFA Foreground) subset of the spec. The terms Full & Foreground come from the XFA spec. I would have preferred XFAF to have a different name, since it is the display/foreground layer that isn't XFA when using it.

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.
