[Digikam-devel] extragear/graphics/digikamimageplugins/unsharp

Gilles Caulier
SVN commit 514792 by cgilles:

Digikam 0.9.0 from trunk : Unsharp Mask tool :

- New algorithm inspired from ImageMagick instead Gimp algorithm. This one is more simple to understand... (I think that Gimp source code is really a wrong inspiration...)
- Port algorithm to DImg. Support of 16 bits images.
- Fix dialog settings widgets layout.

Cannot say about code/algorithm quality but very often transformations in ImageMagick are giving better results.

When i said that "Gimp source code is really a wrong inspiration" i want said
that the gimp code is very complex to study. Sometimes there is no comment.
Also, it's a pure C implementation, not C++. It's a old school
implementation...
