[Digikam-devel] Compile problems with png library

[Gilles Caulier]

Ah, I'm happy to see you Gerhard (:=)))...

You have right. LIB_PNG isn't in the rules to link digikam part from the 
makefile.am. I will fix it.

I suspect that all is right in my computer because libpng is added by default 
in ldd configuration.

Nota; Gerhard, i need you to polish the new advanced Noise Reduction tool to 
remplace current despeckle tool in DigikamImagePlugins. The results are 
similar than Noise Nija program for Photoshop. Please help me to finalize the 
GUI, especially the settings.

Look in your mail from yesterday, i have sent a message about in this ML.
