Hmm... in this case, it seems to be a bug...?
What I would like to plead with SC's authors to do is implement object copying from an existing objects file into a new image's objects file. For example, if I have a screen capture A.png, which I've annotated with callouts etc., which are formatted just the way I like them; when I capture B.png, I would like to be able to tell SC to pull the objects (all of them, perhaps) from A.png.objects and stick them in B.png.objects, then reload the view of B.png. Any objects whose coordinates/dimensions exceed the new image's size could be "fixed" to fall within the new image's boundaries. Of course, I would expect to have to move the callouts etc. around to the proper places, maybe delete the ones I don't need, edit text in the textboxes so the captions are correct for the new image, and so on. I just think it would save a lot of time for users, instead of drawing all those objects on the new image, and changing the attributes to what they need to make the appearance consistent with all the other image capture markup.
Hope I'm clear...
Thanks and regards,
