Constructor
GdkPixbuf.Pixbuf.new_from_data
Declaration [src]
GdkPixbuf*
gdk_pixbuf_new_from_data (
  const guchar* data,
  GdkColorspace colorspace,
  gboolean has_alpha,
  int bits_per_sample,
  int width,
  int height,
  int rowstride,
  GdkPixbufDestroyNotify destroy_fn,
  gpointer destroy_fn_data
)
Description [src]
Creates a new GdkPixbuf out of in-memory image data.
Currently only RGB images with 8 bits per sample are supported.
Since you are providing a pre-allocated pixel buffer, you must also
specify a way to free that data.  This is done with a function of
type GdkPixbufDestroyNotify.  When a pixbuf created with is
finalized, your destroy notification function will be called, and
it is its responsibility to free the pixel array.
