Sketches as pictures

[IronHorse]

How do i export a sketch as a picture. I need to export the outlines
of a sketch. Add new lines etc. in Photoshop and to import the picture back so I
can use decal to put It on the face of an object. I can do this, but I get wrong
size and proportion.

You can dimension the re-imported image to correct scale, but if aspect ration somehow got messed up I don't know how to fix that.
