Vipspdfload_buffer

Declaration [src]

int
vips_pdfload_buffer (
  void* buf,
  size_t len,
  VipsImage** out,
  ...
)

Description [src]

Optional arguments:

  • page: %gint, load this page, numbered from zero
  • n: %gint, load this many pages
  • dpi: %gdouble, render at this DPI
  • scale: %gdouble, scale render by this factor
  • background: VipsArrayDouble background colour

Read a PDF-formatted memory buffer into a VIPS image. Exactly as vips_pdfload(), but read from memory.

You must not free the buffer while out is active. The VipsObject::postclose signal on out is a good place to free.
