Set a bitmap on an image page-object

Wraps FPDFImageObj_SetBitmap. PDFium copies the bitmap's pixel data into the document immediately; closing the bitmap handle afterward is safe (and recommended for deterministic release).

Usage

pdf_image_set_bitmap(image, bitmap)

Arguments

image

A pdfium_obj of type = "image".

bitmap

A pdfium_image_buffer.

Value

Invisibly returns the parent pdfium_doc.

Details

Typical workflow:

bm <- pdf_bitmap_new(width = 100, height = 100)
pdf_bitmap_set_buffer(bm, my_bgra_bytes)
img <- pdf_image_new(page, jpeg = raw(0), bounds = c(0, 0, 200, 200))
pdf_image_set_bitmap(img, bm)
pdf_bitmap_close(bm)

pdf_image_new() for the JPEG-only path that doesn't require a bitmap.
