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

[Daniel T. <de...@ti...>]

Hi Brian!
 
I am currently working on a "stacker" that reacts on layer resizing.
 
Its a function that works with the x,y,h,w of the layers added.
 
If you have layer 1 and layer2 and they are exacltly 5 pixels space
between them, if you resize layer 1 so the space is say 15 pixels
between them, layers 2 will be moved so its still 5 pixels between them.
 
But with movement this one is not the option, this is just for sizing,
however you should have a look at the groupmanager example who deals
with positions, i dont know if thats the thing you are looking for but
it might help you out.
 
Regards
Daniel

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



Hello everyone, I have been at this for about (well all night) and I
seem to be missing something... What am I trying?
 
Well, When one layer grows, I need another layer to shring
accourdingly.. Plus, if I move one layer I need to other layer to move
accourdingly.. Everything I have tried seems to be close, but not
there... Not to mention looking at the code in scrollbar.js, but being a
little week in math?? Well, lets say its not my cup of tee..
 
Please help...
 
example: 
 
ViewWin is my larger Window and ScaleViewerContainer is my smaller
window..
The two objects that need to interact are ViewLyr[lyrid] where lyrid is
the layer in focus (larger) and ScaleViewer the smaller one.
-Both of the obove are contained in there parent layers ViewWin ->
ViewLyr[lyrid] and ScaleViewerContainer -> ScaleViewer..
 
  this.rh = this.ViewWin.getHeight()/this.ScaleViewer.getHeight();
//ratio
  this.rw = this.ViewWin.getWidth()/this.ScaleViewer.getWidth();
  this.sw =(this.ViewLyr[lyrid].getWidth() -
(this.ScaleViewer.getWidth()/this.rw))/this.rw;
  this.sh =(this.ViewLyr[lyrid].getHeight() -
(this.ScaleViewer.getHeight()/this.rh))/this.rh;
 
  this.nh =  this.ScaleViewerContainer.getHeight() -
(this.sh-this.ScaleViewer.getHeight());
  this.nw =  this.ScaleViewerContainer.getWidth() -
(this.sw-this.ScaleViewer.getWidth());
  //this.rh = this.ViewWin.h/this.ScaleViewerContainer.h; //ratio
  //this.rw = this.ViewWin.w/this.ScaleViewerContainer.w;
  this.rx = (this.ViewLyr[lyrid].getX()*-1)/this.rw;
  this.ry = (this.ViewLyr[lyrid].getY()*-1)/this.rh;
 


  this.ScaleViewer.setSize(this.nw,this.nh);
  this.ScaleViewer.setLocation((this.rx/this.rw),(this.ry/this.rh));
 
Thanks, Brian Hayes
