  sourceRectAtTime() of shape layer before trim path ?

  Posted by Anders Hattne on February 20, 2017 at 5:21 pm

  Hello!
  I am trying to automate drawing some shape layers with trim path – the time it takes for the line to be drawn should depend on the length of the line which I got with sourceRectAtTime()
  But I think my problem is that when trim path is at 0% sourceRectAtTime will give me a value of 0 and draw the line in no time
  Is there any way of getting the size of the layer before trim paths?

  layerS= thisLayer.sourceRectAtTime();
h = layerS.height;
w = layerS.width;
len = length([0, 0], [w, h]);

  trans = linear(len, 200, 800, minTim, mxTim);
a = linear(time, startTime, startTime + trans, 0, 100);

  Solved!
  For now increasing the minimum time seems to have done the trick!!
