  Anchor Point Position

  Posted by John Abbott on July 18, 2023 at 3:31 pm

  I have put the following expression to anchor point property of the text layer.

  const sourceRect = thisLayer.sourceRectAtTime(0, false);

  let { width, height, top, left } = sourceRect;

  const { fontSize, leading, autoLeading } = thisLayer.text.sourceText.style;

  const lineGap = autoLeading ? fontSize * 1.2 : leading;

  const textSize = fontSize / 2;

  const numLines = Math.max(

  text.sourceText.value.split(/[^\r\n\3]*/gm).length – 1,

  0

  );

  height = lineGap * (numLines – 1) + textSize;

  topLeft = [left, -textSize];

  thisLayer.add(topLeft, [0, height]);

  I have found it from https://motiondeveloper.com/blog/dealing-with-descenders to position the anchor point to the bottom left corner, ignoring descenders. But it is not working, placing anchor point at some distance from expected position(check screenshot attached).
