NAME

image_matchstorage - test if two vids share the same underlying storage

SYNOPSIS

true or false
image_matchstorage( v1, v2 )

DESCRIPTION

This function can be used to determine if two vids share the same underlying backing store. This can be helpful in cases where one might need transition based on visual properties that are inherent to the backing store, as there are no strong equality tests for regular vids as they are all treated as unique.

EXAMPLE

function image_matchstorage0()


      a = fill_surface(32, 32, 0, 255, 0);


      c = fill_surface(32, 32, 255, 0, 0);


      b = null_surface(32, 32);


      image_sharestorage(a, b);


      assert(image_matchstorage(a, b) == true);


      assert(image_matchstorage(a, c) == false);


      image_sharestorage(a, c);


      assert(image_matchstorage(a, c) == true);
end
