  Aligning scaled images edge to edge

  Posted by Ryan Paterson on May 31, 2014 at 9:21 pm

  Trying to have a horizontal slideshow where each image is auto-placed next to the image previous to it, the caveat is I have to scale some of the images to be the right size, which is where my expression breaks. Here’s what I’ve got-

  l = thisComp.layer(index-1);
  x = l.transform.position[0] + (l.width*(l.transform.scale[0]/100));
  y = value[1];
  [x, y]

  Try this. Position and scale Layer 1. Everything else gets this position expression and will align to the right edge of the preceeding layer:

  L = thisComp.layer(index-1);
  rEdge = L.position[0] + L.width*L.scale[0]/200;
  x = rEdge + width*scale[0]/200;
  [x,value[1]]
