Struct PdfPageAnnotationObjects

Source
pub struct PdfPageAnnotationObjects<'a> { /* private fields */ }
Expand description

The page objects contained within a single PdfPageAnnotation.

Content in an annotation is structured as a stream of PdfPageObject objects of different types: text objects, image objects, path objects, and so on.

Note that Pdfium does not support or recognize all PDF page object types. For instance, Pdfium does not currently support or recognize the External Object (“XObject”) page object type supported by Adobe Acrobat and Foxit’s commercial PDF SDK. In these cases, Pdfium will return PdfPageObjectType::Unsupported.

Page objects can be retrieved from any type of PdfPageAnnotation, but Pdfium currently only permits adding new page objects to, or removing existing page objects from, annotations of types PdfPageAnnotationType::Ink and PdfPageAnnotationType::Stamp. All other annotation types are read-only.
