save_to_callback

Description:

[ Version ( since = "2.4" ) ]
public bool save_to_callback (PixbufSaveFunc save_func, string type, ...) throws Error

Saves pixbuf in format `type` by feeding the produced data to a callback.

This function can be used when you want to store the image to something other than a file, such as an in-memory buffer or a socket.

If error is set, `FALSE` will be returned. Possible errors include those in the `GDK_PIXBUF_ERROR` domain and whatever the save function generates.

See [methodGdkPixbuf.Pixbuf.save] for more details.
