Import Sihlouette roto masks into several Nuke shapes

Today kids, I tell you how to split imported Sihlouette shapes into Nuke RotoPaint nodes.

In SihlouetteFX select several nodes.
Go File->Export->nuke 6.2+ Shapes  and save Nuke project

I tried to use also File->Export->Nuke Shapes but in Nuke 7.0 it wasn't opened properly

Open saved project in Nuke. There is a single RotoPaint node. It contains several layers with several shapes in each.
I need separate layers into many nodes to use them separately.

To do this I wrote following script:

Image resize in Nuke

So here we have two filters:
1) Crop
2) Reformat

To cut a part from an image we use Crop. It also has option "reformat". Reformat cuts also borders behind area. If "Reformat" is disabled, black borders remain after crop.
