[Digikam-devel] blowup handbook

[Oliver Dörr]

Just an additional Remark,

reading the handbook, the mentioned values for detail preservation and 
smoothing makes a lot of sense together. So i'll suspect a bug in the 
plugin allowing values that does notz make sense.

Could somebody who understand the underlying algorithm check that?
