Hi,

this may be a noob question, but i'm really new to this.

I want to engrave this one on a 3mm a4 plywood:

It's a 2 layers image, one for the cut, and one for the engraving. When i click the second infill button i get this:

And if i select the image border and delete it, i get this (the blue outline is the cut layer):

But i want to invert the engraved part with the white one, like this (i did this with an image editor):

There is a way to invert engraved area in XCS directly? or i need to use an external software? 

Thank you very much.
