  sourceRectAtTime with a paragraph text layer

  Posted by Joshua Dunson on November 19, 2018 at 7:30 pm

  I’m trying to create a text layer that scales relative to the dimensions of any given comp regardless of aspect ratio. I’ve written the following expression and placed it on the scale attribute of a “paragraph” text layer (paragraph for word-wrapping if needed). The expression works, but seems to ignore the bounding box of my text and looks only at the text written. I’d like it to have my expression scale based on the bounding box dimensions. Any help from all you expression whizzes out there is greatly appreciated! Thanks.

  box = thisLayer.sourceRectAtTime(time);

  x = (thisComp.width/box.width)*100;

  [x,x]

  There’s a boolean true or false you can add as a second parameter after time to the sourceRectAtTime input, which return either the size of the box or the extents of the content depending on value.

  Thanks a million for taking the time to share that!

  I adjusted (time) to read (time, true) and that seemed to be enough. I’m still running it through the gauntlet, but it appears to be holding up.
