Stroke line-cap style of a path page-object

Returns the PDF line-cap style applied to a path's stroke. Maps to the LC operand in the page content stream and corresponds to PDFium's FPDFPageObj_GetLineCap.

Usage

pdf_path_line_cap(obj)

Arguments

obj

A pdfium_obj of type "path" from pdf_page_objects().

Value

Character scalar; one of "butt" (square cap aligned with the stroke endpoint, the PDF default), "round" (semicircular extension past the endpoint), or "projecting_square" (square cap extending one half-line-width past the endpoint).

pdf_path_line_join(), pdf_path_stroke().

Examples

fixture <- system.file("extdata", "fixtures", "shapes.pdf",
  package = "pdfium"
)
if (nzchar(fixture)) {
  doc <- pdf_doc_open(fixture)
  p <- pdf_page_load(doc, 1)
  path_obj <- Filter(\(o) o$type == "path", pdf_page_objects(p))[[1]]
  pdf_path_line_cap(path_obj)
  pdf_page_close(p)
  pdf_doc_close(doc)
}
