  More elegant Text Scale solution

  Posted by Chris Meadmore on October 17, 2018 at 4:52 pm

  Hi,

  I’ve written this expression:

  layerWidth = thisLayer.sourceRectAtTime(time).width;
maximumWidth = 650;
percentageOfMaxWidth = layerWidth / maximumWidth * 100;
leeway = 100 - percentageOfMaxWidth;
if (layerWidth < 650) [110,110]
else [100 + leeway, 100 + leeway]

  Which works really well on my text scale… as the text goes beyond a 650 pixels it begins to scale down to stay within the comp. Issue is as it scales down it begins to jump larger and larger percentages.

  What I really want is for the right side of my text box to remain at the 650 pixel distance.

  Can anyone help?

  FYI, text is left aligned.

  Thanks.

  This works for me:

  layerWidth = thisLayer.sourceRectAtTime(time).width*scale[0]/100;

  if (layerWidth!=0 && layerWidth>650) {
value * 650/layerWidth;
} else {
value;
}

  should be fine unless you’re also having parenting and scaling going on in that parent…
