It may also help to lock the screen for visual effect within a given rectangle, thereby reducing the number of pixels that need to be updated. If the images are of equal dimensions and with the same loc, you can refer to the rect of one of them, otherwise you can have an invisible graphic as reference or just the local screen coordinates where you would like the effect to take place, like this:
lock screen for visual effect in rect(rect of image “test1”) — or the direct coordinates as param (200,200,500,400) hide image “test1” show image “test2” unlock screen with visual effect dissolve very fast Regards Tore Nilsen > 30. des. 2017 kl. 23:06 skrev Sannyasin Brahmanathaswami via use-livecode > <use-livecode@lists.runrev.com>: > > So: if the effectRate defaults to 2000 (which is what I'm seeing here on > desktop) and you have > ------ > Show image "grand-canyon" with visual effect dissolve very fast > ------- > # theoretically 1/5 of 2000 = 400 milliseconds > > why is the script profiler saying this line takes 4765 milliseconds top > execute? > > The dictionary has two methods: if you look up "show" it appears you should > be able to perform this "directly" > > But, under the visual effect command the suggested method is to lock screen, > make the change then unlock the screen with visual effect.
