gdkcut_pixbuf_assert_equal ()

void
gdkcut_pixbuf_assert_equal (const GdkPixbuf *expected,
                            const GdkPixbuf *actual,
                            guint threshold,
                            ...);

Passes if expected == actual . If difference of each corresponding pixel value is within threshold, expected and actual are treated as equal image.

If threshold is 3, pixel value of expected at (1, 1) is 127 and pixel value of actual at (1, 1) is 131, actual doesn't equals to expected . If pixel value of actual at (1, 1) is 130, actual may equal to expected . (All other corresponding pixel values are needed to fill this condition.)
