gdk:surface-scale (object)

object -- a gdk:surface object
scale -- a double float with the scale

Accessor of the scale slot of the gdk:surface class. The gdk:surface-scale function returns the internal scale that maps from surface coordinates to the actual device pixels. When the scale is bigger than 1, the windowing system prefers to get buffers with a resolution that is bigger than the surface size, for example, to show the surface on a high-resolution display, or in a magnifier.

Compare with the gdk:surface-scale-factor function, which returns the next larger integer.

The scale may change during the lifetime of the surface.
