[magick-users] Compositing using DissolveCompositeOp

[Elie Zedeck RANDRIAMIANDRIRAY]

Yes, you are right Pete. There is no such thing as Evaluate in the Magick++.

I think the Magick++ binding is quite obsolete! I see lots of C 
functions not seen in the Magick++, or the documentation is quite old.

It seems that only the MagickCore and MagicWand is the only ones being 
updated. There is something right that I'd like to do, which involve 
using function in the C-API. This is not present in C++.

Now, I think I'm going to have to convert all my Image manipulation 
codes to use MagickCore because of these reason. I've spent way too many 
times trying to figure-out how to do things in C++. I'll backup all my 
codes into the Repository now.
