RE: [Dynapi-Help] Setting the scale for one object based on another.

[Brian H. <bg...@ke...>]

Raymond,

	This is not a LayoutManager, but it does offer a way to embed an
image into a layer, and allows the image to react to changes to that layer..
Example, if you resize your layer, your image will resize as well.. Plus, I
added your slideTo function, and created a GrowTo function that slides and
grows similar to the slideTo function and a simpler Grow function that just
grows the layer/Image accourdingly.... Please let me know your thoughts...

<for everyone who has help me, thank you!>

As to the below, I am working on this, and I do have a working model, but it
is not where I want it to be... What I belive to be a good way of doing this
is to pass another object into the imageobject.js, and have them react to
each other based on their sizes.. So, if one layer grows, have the other
layer shrink or grow, it on layer moves, have the other move in the same
direction or oposite direction, etc... What do you think? Something like,

Var Lyr1 = new ImageObject(null,0,0,100,100,null,{ImageSrc:'/img1.jpg'});
Var Lry2 = new ImageObject(null,0,0,400,400,null,{ImageSrc:'/img2.jpg'});

Lry2.setReactTo(Lry1,{react:false,ratio:1.5}); //When Lry1
moves,grows,shrinks react to it, in the same direaction by default..
Lry1.setReactTo(Lry2,{react:false,ratio:1.5}); //When Lry2
moves,grows,shrinks react to it, in the same direaction by default..

// {react:false} //causes the two layers to react opposite of each other..
/ratio:1.5 //is the factor in wich to react to each other..

What do you think?


Thanks,

	Brian Hayes

You might want to try using the onresize and onlocationchange events to make
the adjustments.

I believe a LayoutManager is in the making but it you can create one then
that would be cool.
