Automatic font size on text based on its width
Hello,
I’m trying to make text that decrease its font size depending on its length if its bigger than certain value. I’m trying to use while statement but with no success.The idea is lets say we have a text with font size 75 and when you are typing text and the text width reach lets say 500 we want font size to start going down.
tWidth = thisLayer.sourceRectAtTime().width;
fSize = 75;while(tWidth > 500){
fSize--;
thisLayer.text.sourceText.style.setFontSize(fSize);
tWidth = thisLayer.sourceRectAtTime().width;
};text.sourceText;

Is there a particular reason why you don’t decrease the size? If you want to decrease the scale, you can use this as an expression, applied to scale:
maxWidth = 500;
thisWidth = sourceRectAtTime(time,false).width;
ratio = Math.min(maxWidth/thisWidth,1);
value*ratio

Thanks, that worked in my case. 🙂

speaking of font expressions, is there a way to have a text layer reference another layer, and have its own type of font-style-expression? like
thisComp.layer("Main").text.sourceText.style.setFauxBold(1).setFauxItalic(1).setFontSize(900) -
Something like
style.setFauxBold(1).setFauxItalic(1).setFontSize(900).setText(thisComp.layer(“Main”).text.sourceText.value)

Ahh, thanks.
I needed to also do it for a long else-if statement. I figured it was the same way, setting the style and the text result in each of the “else if” outputs.
