frame-size question

Are there any frame filters that add on to the original size of the picture in which the frame is being put around (making the photo larger and not cropped)?

If not, is it possible with Filter Forge to create such?

Thanks!

No, its not possible to extend the output area around the image, however it is possible to scale down the image instead - like Craig said, check out a few zoom snippets (you might need the proportional gradient snippets too).

This may not be the best and fastest solution. You may get aliased details due to the lack of true resampling, and you actually throw away original image information. The best solution would be to extend the canvas prior to filtering in filter forge (i.e. pad the borders).

If you go for the build in scale down solution and encounter alias artifacts, try blurring the picture slightly before scaling down (this is somewhat equal to what is going on in true resampling).

Well, actually this should not have much influence here - what I mean is that the current "normal" approach we use to scale down the image is equal to nearest neighbour resampling. High frequency areas may suffer greatly by this approach. Ofcourse it all depends by the antialias settings, but the edges only approach really does a bad job here and you're forced to use the "All Pixels" option if you really want good quality. This is slow as hell, and thats why you might be better off hooking up a prefiltering blur.

Check out these two images - the first is using "Edges Only", the second is not using antialiasing at all:

Normal (AA: Edges Only, 5 Samples):


Prefiltered (AA: None):
