image_matchstorage(3) Arcan Lua API image_matchstorage(3) 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 un- derlying 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 SEE ALSO: image April 2025 image_matchstorage(3)
