When I import images (png files) and trace them in Inkscape and they become really smooth and vectorized I then have trouble drawing over them - editing them. Well I guess that is not the whole problem. The whole problem is that I cannot re-size them in inkscape because the imported image is separate from all of the additions - the drawing - that I did over the image. These two are separate things. I am wondering how if it is possible to bind these two things together because I am assuming that I am not changing the original image I am just drawing stuff - superficially - on top of it.
