[Digikam-devel] [patch] [digikamimageplugins SVN 0.9.0] patch for noisereduction.cpp

[Peter Heckert]

Hello,

discovered another error in noisereduction.cpp, that caused vertical 
smear in images.
This bug causes, that  horicontal edge detection buffer is used as 
template for vertical blurring operation, thats  bad ;-)
It differs from gimp version.
Patch appended.
This patch should give doubled image quality, the same as in gimp plugin.

In preparation for 2-dimensional filtering I rewrote the gaussian filter 
and published this as
dcamnoise2-0.64 in gimp registry.
<http://registry.gimp.org/plugin?id=5610>
It turned out, that the new filter gives much better sharpness. I tried 
to port this to digikamimageplugins,
but had no success until now, it crashed (memory leaks ;-) . I am 
working on it.

Another theme:
Is user interface broken?
While debugging I had the problem, that mousepointer stays connected 
with the gamma rubber.
That means,  I remove the mouse from gamma rubber and  the rubber still 
is connected to mouse.
(Excuse my english, if you don't understand, please ask, I will try to 
explain better)

greetings,

Peter
