The Artrage manual states:

"Important: Including the current painting in your script prevents
the script being played back at larger size later. Do not turn the
option on unless you specifically want paint that is already on the
canvas to be included in script playback."

This seems like a very severe limitation. The query is about workarounds.

As a minimum, I would like to trace, in Artrage, an imported photo of a pencil sketch, script an artwork based on it, and play it back at larger size. The layer that contains the imported photo could be discarded if required to enable larger size playback.

What can be done? If resampling cannot currently be accomplished as part of larger size script playback, consider adding a feature.
