If you mean the size of the stage. you just could scale the stage to it's needed size with jquery in the compositionReady section. Just keep the ratio of the element, were it's embedded, the same as the stage ratio and try this piece of code:
thanks for the response. When I scale the stage - sure it gets smaller - but now all my elements are off the edges and have not scaled with the stage. Do you understand what I mean?
this code shouldn't just scale the stage, it scales everything within too.
You can't just scale the stage inside edge via the properties window, thats right.
The code shrinks your composition to the size of the element, where its embedded.
