sourceRect text layers which play off each other.
Hi,
I’m using sourceRect.time to scale a text layer to a specific width. Works great.
Now I have 2 layers which have the same expression applied and I’m trying to rig them off each other. So:
Layer A scales to designated width unless Layer B is smaller in which case follow that.
I’ve almost got it working with one layer, it scales itself depending on length but also monitors the other layer and adjusts accordingly. When I apply this same expression to the other layer it doesn’t work.
Is there a way to do this without introducing extra layers / Nuls?
Thanks for any help! Kinda urgent 😀
textwidth = thisLayer.sourceRectAtTime().width;
s = 100*1700/textwidth;
b = thisComp.layer("Layer A").transform.scale;if(s < 100) [s,s] else b;

Oops… think I solved it on my own. Just needed a smoke break!
a = thisLayer.sourceRectAtTime().width;
b = thisComp.layer("Layer A").sourceRectAtTime().width;
c = 100*1700/a;
d = 100*1700/b;if(a > b) [c,c] else [d,d];

Never mind, still not solved.
The layers are playing off each other perfectly but I need to cap them at 100% so they don’t scale beyond that.

There’s probably a better way.
You can clamp your scale to not go above 100 for example.
s = clamp(c,0,100);
[s,s]

Thanks Scott!
I’ve brought a coder into the mix and he produced the below expression which worked perfectly although we’re now struggling with trying to apply it to 3 layers and find the max value from them.
Any ideas how to do this? Thanks so much for the help!
Layer1Width = thisComp.layer("LINE_01").sourceRectAtTime().width;
Layer2Width = thisComp.layer("LINE_02").sourceRectAtTime().width;Layer1Ratio = 100 * 1700 / Layer1Width;
Layer2Ratio = 100 * 1700 / Layer2Width;Layer1Ratio = Layer1Ratio > 100 ? 100 : Layer1Ratio;
Layer2Ratio = Layer2Ratio > 100 ? 100 : Layer2Ratio;if(Layer1Width > Layer2Width ) [Layer1Ratio, Layer1Ratio] else [Layer2Ratio, Layer2Ratio];

So you try to go for the largest layer, but not over 100?
Layer1Width = thisComp.layer("LINE_01").sourceRectAtTime().width;
Layer2Width = thisComp.layer("LINE_02").sourceRectAtTime().width;
Layer3Width = thisComp.layer("LINE_03").sourceRectAtTime().width;LayerRatio = 100 * 1700 /Math.max( Layer1Width, Layer2Width, Layer3Width);
(LayerRatio<100) ? [LayerRatio, LayerRatio] : [100,100];You can put however many layers you wish.

That is PERFECT!
Thank you
