Zooming in and out on an image (Flash5)

[ericinho]

I want to zoom in and out on an image (it's actually a thumbnale which pops up). Or if you want, to have a small image 'grow' to a larger format.

I tried it with scaling + tween, but it is hardly a smooth transition.

are there better ways of doing it (without manually adjusting each frame of the tween)?

have you tried to increase you fps ? :bounce:

i actually did a zoom once, and it worked out pretty good. here is what i did:



MovieClip.prototype.zoomIt = function() {
if (_root.yourMCname._xscale>300) {
clearInterval(intId);
} else {
_root.yourMCname._xscale = _root.yourMCname._xscale+5;
_root.yourMCname._yscale = _root.yourMCname._yscale+5;
}

then on the movie clip (MC) highlight it and go to actions
and add this:


onClipEvent (load) {
intId = setInterval(zoomIt, 100);
}



hope this helps.

yes, that is a good script way, as there are several others.
But what got my attention was the smooth part:

I tried it with scaling + tween, but it is hardly a smooth transition.
that is only fixed with fps increase.

[megalene]

yes you are right fps is the best way to get a smooth animation.

[Guig0]

and you got a nice code there. ;) you made it?

[ericinho]

thanks for the code, I will try that.

about the fps.

I am currently running the anim at 24fps and for the main I want to keep that.

If I load an external SWF onto the main, will the SWF keep its own (and faster) FPS, or will it adapt to the framerate of the main swf?

[Guig0]

24 fps is good!

and, no. the loaded swf will be with the same fps as the main.

You can chage frame rate using AS.

[Guig0]

but will affect all movies, main included. i think :-\

[ericinho]

thanks all.

i don't think the fps is the problem, but the scaling of the image.

[Guig0]

fps = smoothnes

unless you did something very wrong :-\ if you can post your fla here i´ll take a look at it :)
