I have an object, it is a t-shirt which is black. I want to get this t-shirt but brown. I can't just fill it because it is a photo, not homogenous color. It is the pure shape of it, not square -> So I tried to make a brown square, and then clip->set when I had both selected. I get only white space, not brown t-shirt.
In my opinion, the solution is to get only an outline of this t-shirt and then to fill it with brown color. But I don't know how to get an outline of it.
Will you give me an advice, how to do that? I'm very new in Inkscape. Thank you!
