Algorithm:
|
|
|
|
Scale image up.
|
|
Resynthesize with:
|
|
corpus = original size image
|
|
in map = original size image but scaled up and down to blur
|
|
out map = scaled up image
|
|
|
|
This restores the detail that scaling up looses.
|
|
It maintains the aspect ratio of all image features.
|
|
|
|
Unlike the original smart-enlarge.scm, this alters the original image.

original did not accept an alpha channel
