Like this. I don't know how to do this - I create a bone for a picture and binded it with B, after that I'm supposed to double click on the image, right? Well, this doesn't work. I don't see the square with the white triangles that allows me to deform it, it's only a square with white dots that allows me to resize the image, but not to deform.

I'm using the free version, but deforming isn't added as a premium feature on the website. I want to buy the pro version soon ... does anyone know if it's possible to deform without the pro version?

Edit: https://youtu.be/V0ehOfGP5XY?t=7m8s Here someone is doing it too! When I double click this frame with the white triangles won't show up, it's only the normal frame with the white dots..

Deforming is not officially supported at all and not supported by ay Sprite rplay-back API's sucvh as for Unity, Construct, etc.
Also, it only achieved proof of concept/experimental status, and was an intended as pro-only feature, so it might not be availible in the free version.

The trick is you need to change the "Drag new ityem as" drop down to skins as opposed to sprites. Did you spot that in the first few seconds of this video?
