Constructor

VipsImagemagickload_buffer

Declaration [src]

int
vips_magickload_buffer (
  void* buf,

Description [src]

Read an image memory block using libMagick into a VIPS image. Exactly as vips_magickload(), but read from a memory source.

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

Optional arguments

  • page: gint, load from this page
  • n: gint, load this many pages
  • density: gchararray, canvas resolution for rendering vector formats like SVG
