Fit to Comp Width

[Dan Ebberts]

Assuming your layer is selected and your comp has focus, this should work:

app.executeCommand(app.findMenuCommandId(“Fit to Comp Width”));

Or, you could do it this way:

var myComp = app.project.activeItem;
var myLayer = myComp.layer(1);
var s = (myComp.width*myComp.pixelAspect)/(myLayer.width*myLayer.source.pixelAspect)*100;
myLayer.property(“Scale”).setValue([s,s]);

Hi Dan,

Can you please provide similar code for “Fit to Comp” ?

[Dan Ebberts]

I guess that would be like this:

var myComp = app.project.activeItem;
var myLayer = myComp.layer(1);
var s = myLayer.property("Scale").value;
var x = (myComp.width*myComp.pixelAspect)/(myLayer.width*myLayer.source.pixelAspect);
var y = myComp.height/myLayer.height;
myLayer.property("Scale").setValue([s[0]*x,s[1]*y]);

Or an expression like this:

x = (thisComp.width*thisComp.pixelAspect)/(width*thisLayer.source.pixelAspect);
y = thisComp.height/height;
[value[0]*x,value[1]*y]

Thank you very much, and especially for replying even after so many years to this post

Hi Dan,

Thanks for the expression.

The question is, is it possible to do the same for text? it doesn’t have a source parameter and the expression doesn’t work

[Dan Ebberts]

I guess it depends on what you’re after exactly. If you just want to scale the text so that its width matches the comp width, a scale expression like this should work:

s = (thisComp.width/sourceRectAtTime(time,false).width)*100;
[s,s]
