read_pixel_bytes

Provides a Bytes buffer containing the raw pixel data; the data must not be modified.

This function allows skipping the implicit copy that must be made if get_pixels is called on a read-only pixbuf.

Parameters:

this

A pixbuf

Returns:

A new reference to a read-only copy of the pixel data. Note that for mutable pixbufs, this function will incur a one-time copy of the pixel data for conversion into the returned Bytes.
