Auto Scaling expression

[Dan Ebberts]

What do you mean by “takes into account the keyframes”? In what way?

So if I were to have a keyframe in there that changes the value from 100% to 50% it’d actually do that rather than be a static value that the expression makes it

So something like this?


if (numKeys > 0){
margin = 0;
text_width = thisLayer.sourceRectAtTime(time).width;
text_height = thisLayer.sourceRectAtTime(time).height;
rect_height = thisComp.layer("S").height*thisComp.layer("S").scale[1]/100-2*margin;
rect_width = thisComp.layer("S").width*thisComp.layer("S").scale[0]/100-2*margin;
s = Math.min(rect_width/text_width*100, rect_height/text_height*100);
[s,s]
}else
value

Sorry, that was backwards:


if (numKeys == 0){
margin = 0;
text_width = thisLayer.sourceRectAtTime(time).width;
text_height = thisLayer.sourceRectAtTime(time).height;
rect_height = thisComp.layer("S").height*thisComp.layer("S").scale[1]/100-2*margin;
rect_width = thisComp.layer("S").width*thisComp.layer("S").scale[0]/100-2*margin;
s = Math.min(rect_width/text_width*100, rect_height/text_height*100);
[s,s]
}else
value

Sort of, I still want it to actually change the scale no matter what to fit the box that I have it scaling to, but just include the keyframes I have as an additional factor into the value to scale it to
