2017-06-27Changed the return type for annotation APIsJane Liu
Before: When returning FPDF_ANNOTATION, the APIs would take in a FPDF_ANNTOATION* and write the handle of the annotation to it, while returning a boolean as status. This CL: This CL changes the APIs to directly return FPDF_ANNOTATION, which would be null on failure. Also adds more null checks within the annotation APIs.

This function copies the selected text from a form text field or form combobox text field into the buffer parameter and returns the length of the selected text string. When buffer is a nullptr or buflen is less than the length of the selected text, this function does not modify the buffer and only returns the selected text length.

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.
