Description Aaron Williams 2003-02-11 01:46:59 UTC

Version:           3.0 (using KDE 3.1.0)
Installed from:    compiled sources
Compiler:          gcc version 2.95.3 20010315 (release)
OS:          SunOS (sun4u) release 5.7

Some features present in kview 3.0.x are now missing in 3.1.  So far the following features appear to be missing:

Gamma adjustment
Brightness Adjustment 
Greyscale conversion
Smoothing
Image info

Normally something like this would be a wish list item, but since this was present in 3.0 it certainly should be available in KDE 3.1.

Right now the most important feature missing is the lack of gamma correction.

On an off-topic, it would also be useful to display the current gamma setting for png files (and other formats with that info) in the kfile-plugins in kdegraphics.  Also, there should be a better method of adjusting the gamma in Kuickshow.

Kuickshow wishlist items belong to Kuickshow - not KView ;-) 
 
Nevertheless it's unimplemented features and so it's a wishlist item. But: I believe 
it should be pretty trivial to get this working with the current KView 3.0. The 
plugin interface is not public yet, but if you want to experiment: look at 
kdegraphics/kview/modules/template/ adjust to your needs and 
kdelibs/kdecore/kiconeffect.h: static void toGamma(QImage &image, float value);

I've already started coding something up after discovering the plugin 
interface.  I'm rewriting the gamma correction code so it should be a 
lot faster than the old code.

Cool. Please keep me informed; I'd be happy to include it for KDE 3.2. And if 
you want to distribute the plugin seperatly, keep in mind that I'm going to 
break compatibility with 3.2. I hope to get the interfaces stable by then, 
though.

I just added a basic gamma effect to HEAD. If you're interested you can work on improving 
that...

Kview is no more mantained/developed. This bug wish will not be fixed until a new developer will work on it. Moreover this product is not ported to KDE4. On KDE4 it has been replaced by another software. I'm closing this bug as "unmantained". I'm sorry.

Regards.
