Does it work with touch on iPad (holding icon with a finger, drawing with pencil)?

By applying transparency tool or gaussian blur to the clipping layer.

Yes, that would be nice Thanks for reply!

But why it behaves so strange? I add a node (YELLOW) and it add nodes marked with RED area, instead of creating straight line like GREEN.

I tried Mesh Warp tools, Prespective tools and filters, and I have no idea what I can do to fix this. In Photoshop there is an easy way - wide angle lens correction (visible here: https://www.youtube.com/watch?v=03RD17us7Zc). Mesh tool seemed the best for it, but nodes in this tool are not to tell the app where the fixed points should be. Sample image which I'm trying to fix is posted below. It's an ECG, and all grid lines should be straight. How can I straighten it? How can I fix wrapped paper?
