  1 box around two text-layers

  Posted by Kurt Jarnes on July 26, 2023 at 1:38 pm

  Hei. I need help to code a automatic box around two tet layers.
  The two text layers will be the same font, but different size. The first layers will be a heading in large letters. The second will be one ore several lines in smaller letters.
  I need a box that automatic adjust it self on the widest width, and the same for the hight.

  Anyone?

  If you have two text layers (“Text 1” and “Text 2”) and you create a shape layer by just clicking on an empty spot in the comp window with the pen tool, if you apply this expression to the shape layer’s path, you should get a box around your text layers:

  margin = 10;
  L1 = thisComp.layer("Text 1");
  L2 = thisComp.layer("Text 2");
  r1 = L1.sourceRectAtTime(time,false);
  r2 = L2.sourceRectAtTime(time,false);
  ul1 = L1.toComp([r1.left, r1.top]);
  lr1 = L1.toComp([r1.left + r1.width, r1.top + r1.height]);
  ul2 = L2.toComp([r2.left, r2.top]);
  lr2 = L2.toComp([r2.left + r2.width, r2.top + r2.height]);
  top = Math.min(ul1[1], ul2[1]) - margin;
  bottom = Math.max(lr1[1], lr2[1]) + margin;
  left = Math.min(ul1[0], ul2[0]) - margin;
  right = Math.max(lr1[0], lr2[0]) + margin;
  ul = fromComp([left, top]);
  ur = fromComp([right, top]);
  lr = fromComp([right, bottom]);
  ll = fromComp([left, bottom]);
  createPath([ul, ur, lr, ll], [], [], true);

  Tanks, this works perfectly.

  And by adding +, -, / or * in the end of line 10 to 13, I could adjust the shape of the box.
  Ex :

  top = Math.min(ul1[1], ul2[1]) – margin-10;

  bottom = Math.max(lr1[1], lr2[1]) + margin+15;

  left = Math.min(ul1[0], ul2[0]) – margin-60;

  right = Math.max(lr1[0], lr2[0]) + margin+60;

  By adding round corners, Color Emboss and a texture, this is the final :

  Nice. You could also set it up with different variables to define each margin:

  leftMargin = 70;
  topMargin = 20;
  rightMargin = 70;
  bottomMargin = 25;
  L1 = thisComp.layer("Text 1");
  L2 = thisComp.layer("Text 2");
  r1 = L1.sourceRectAtTime(time,false);
  r2 = L2.sourceRectAtTime(time,false);
  ul1 = L1.toComp([r1.left, r1.top]);
  lr1 = L1.toComp([r1.left + r1.width, r1.top + r1.height]);
  ul2 = L2.toComp([r2.left, r2.top]);
  lr2 = L2.toComp([r2.left + r2.width, r2.top + r2.height]);
  top = Math.min(ul1[1], ul2[1]) - topMargin;
  bottom = Math.max(lr1[1], lr2[1]) + bottomMargin;
  left = Math.min(ul1[0], ul2[0]) - leftMargin;
  right = Math.max(lr1[0], lr2[0]) + rightMargin;
  ul = fromComp([left, top]);
  ur = fromComp([right, top]);
  lr = fromComp([right, bottom]);
  ll = fromComp([left, bottom]);
  createPath([ul, ur, lr, ll], [], [], true);
