Rectangles occupied by a character range

Wraps FPDFText_CountRects + FPDFText_GetRect. Returns the rectangular regions occupied by the characters in [start_char, start_char + char_count) on page. Multi-line text produces one rectangle per line; rotated or skewed text produces tighter axis-aligned rectangles per glyph cluster.

Usage

pdf_text_rects(page, start_char = 1L, char_count = -1L)

Arguments

page

A pdfium_page from pdf_page_load().

start_char

One-based character index (matches pdf_text_chars()$char_index).

char_count

Number of characters to cover. Use -1L to include everything from start_char to the end of the page.

Value

A tibble with columns left, top, right, bottom in PDF user-space points. May have 0 rows if PDFium reports no visible rectangles.
