Hello,
I've just found Spriter and I really loved it. It's the software we were expecting for a long time!
I've played with it a little and tried to export some key-frames as PNG images via the File menu. Great feature, since using the SCML or animation info is not suited for everyone. Sometimes we just need a sequence of images.
But I could not find how to re-size/zoom the exporting window. I can drag the "scene" on this window, but cannot change the size or position of the exported images. So, after all, my exported images are always cropped. For example, if I have a character running, the exported images will crop it at the "bellybutton" and contain only its legs.
I also found the the rotated images are very blurred, but I believe another user already commented on it.
By the way, do you have any roadmap for Spriter?
