THotPDF.SetLoadedAnnotationContents Method

Replaces the selected loaded annotation's /Contents string and invalidates its page's render cache

This method preserves the existing appearance and rich text; changing /Contents alone does not rebuild visible FreeText text in /AP

Declaration

procedure SetLoadedAnnotationContents(PageIndex, AnnotationIndex: Integer; const AContents: AnsiString);

HPDFDoc

Name	Purpose
`PageIndex`	Zero-based index or object index used to select an existing item
`AnnotationIndex`	Zero-based index or object index used to select an existing item
`AContents`	Human-readable text stored in the PDF object, action, annotation, or structure element

This member does not return a value

Use zero-based page and annotation indices in a loaded document; if the annotation is not found, this method returns without changing it
Use SetLoadedFreeTextPlainText when explicitly converting a supported FreeText annotation to a new visible ASCII Helvetica appearance
Use SetLoadedFreeTextRichText for the separate rich-text metadata workflow
