Description animtim 2011-03-30 16:07:42 UTC

Version:           unspecified
OS:                Linux

I'd like to have a feature to resize a file using something similar to this:
http://sourceforge.net/projects/imageenlarger/

The advantage to have it integrated in Krita is to be able to use it on several layers at a time.
Then it would be perfect if we could have different settings/layer.
(You could call the feature "Magic Scale" and put it in the menu, near classic "Scale to new size" entry)

Reproducible: Didn't try

for anyone willing to implement this. In the source code, it seems the algorithm is located in "SmillaEnlarger_0.9.0_source/SmillaEnlargerSrc/ImageEnlargerCode".

And from reading "EnlargerTemplate.h" it seems what we have to do is to implement ReadCurentBlock and WriteDstBlock to get and set the data.

Then of course we need a UI, and I don't think it can integrate easilly in our scale dialog nor filter.

I think if we're going to have a magic enlarge, we should use a newer technology using some neural networks. I think they had a bit better results... I remember David Revoy giving some nice examples with text.
