Re: GDK: fast image scaling - how?

[RevX gmx at]

Hi Tristan,

the function header you've sent me looks like the one I need,
BUT I haven't found it in the GDK files that came with gtk+ 1.2.10!
I also haven't found gdk-pixbuf.h. Maybe this is for gtk+ 2 only?
I've tried to look up the API reference for gtk+ 2 but couldn't
find that scaling function, too. Undocumented?

Is there a way to install the "new" GDK (2.0?) in an 1.2 installation?
Or: can you supply the source code for that function?

Anyways, thanks for helping!

Michael.
