Transform every annotation on a page in one shot

Wraps FPDFPage_TransformAnnots. Applies the 6-tuple matrix (a, b, c, d, e, f) to all annotations on page simultaneously — the same matrix shape used by pdf_obj_set_matrix() for page objects.

Usage

pdf_page_transform_annots(page, matrix, page_num = 1L)

Arguments

page

A pdfium_page or pdfium_doc.

matrix

Numeric length-6 vector c(a, b, c, d, e, f).

page_num

One-based page index. Only used when page is a pdfium_doc.

Value

Invisibly returns the parent pdfium_doc.

Details

Polymorphic in page: accepts either a pdfium_page (with parent doc readwrite) or a pdfium_doc plus page_num.
