Resizing Splash screen

[richmond62]

A very long time ago (about 40 years ago) I remember an educational TV programme that started with an image that expanded from a dot in the middle of the screen.

It occurred to me that this might not be a bad idea for a splash screen.

I "had a go" and have attached it here.

The main problem is that to make it slow enough for it not to expand so quickly the viewer doesn't really see it one has to use "wait 2 ticks" in the script, and this results in the expanding
tomato jiggling around in a slightly disconcerting fashion.

I wonder if the scalable vector graphics in the Kickstarter stretch goals will mean that this phenomenon will soon be a thing of the past?

I have tried the same thing with a regular polygon graphic filled with a gradient and still get the same jiggly effect.

It makes it a little better if, inside the repeat, you "lock screen" before doing the "set's" and "unlock screen" after them.

I think, Newbie4, you had better mosey over to the Use-List where this discussion is currently on full-throttle.

Clearly, you question is not Off-Topic...

Thanks for the suggestion, I will

BTW If you make the following changes to your code, it works much smoothly:

Code: Select all

repeat until DIMZ=4
      lock screen
      put (DIMZ - 1) into DIMZ
       set the width of stack "SPLASH" to DIMZ
      set the height of stack "SPLASH" to DIMZ
      set the width of img "tom" to DIMZ
      set the height of img "tom" to DIMZ
      unlock screen
      wait 2 ticks
   end repeat
 

do the same to the second part - add lock/unlock screen before the wait line and remove the setting of the top and left of the image before changing the width/height and change the increment to 1

Hi Hermann,

This all together works on my oldest machine (PPC/Tiger) very good.
And it is pretty fast. I recently used this technique elsewhere and
apply it now for your Halloween-like TOM.

Work really fine on Windows too!
Many thanks for posting this stack.

Wonderful! Many Thanks for updating
your demo stack.

On Linux (at least) when the images resize they leave odd grey trackmarks on screen.

I also wonder how one can slow the resizing down without ending up with a jerking effect.

I am reading this forum from Lubuntu 13.10
where the windowshape property would not
work until I install and configure a compositing
manager.

Later, today, I will boot into Windows and will
report back.

Have a nice weekend!
