Ok, as promised here is some feedback from my testing of your excellent icons set. Unfortunately I couldn't post it to where I uploaded related screenshot due to the limit of 512 characters per comment on Picase Web Albums. So here is link to the picture:
[link] ... and I'm pasting my comment below (sorry if it's too wordy). Please take a look at both.
You can see on the picture that in Lancelot window, the icons on the right side under 'Applications' are scaled to 20x20px (I measured it on the 'Utilities' icon) which is between standard sizes 16x16 and 22x22. That affects their appearance, they are blurred which is in contradiction to the clear left-side icons or 22x22px icons shown next to the applet in Gwenview. I highlighted some examples in the Gwenview window, please compare to the same icons in Lancelot.
It seems that Lancelot instead of picking 22x22 icons (or bigger) and scaling them down, it takes 16x16 (or even 8x8?) size and scales it up which must end up in a bad result. The same happens with bespin icons (with even worse effect).
If my assumption is right, it would explain why kAwOken icons (version of AwOken adapted to KDE4:
[link]) in the same case look so clear: they are only in two sizes: 24x24 and 128x128px so Lancelot has to pick a bigger size than 20x20 and scale it down.
But now, Oxygen icons look pretty clear too and this theme is in all standard sizes (however, unlike Reflektions_KDE4, Oxygen doesn't include 'categories' under 8x8 so the smallest size Lancelot could pick here is 16x16). At first I thought that this is because Oxygen comes with vector icons as well and Lancelot could use them where scaling is involved. But no, the svg folder has only a few icons and none of the 'categories' ones among them. Maybe Oxygen icons simply don't look so bad after scaling up? Or maybe Lancelot always chooses the smallest available version, so 8x8 for Reflektions_KDE4 and 16x16 for Oxygen - in which case Oxygen icons must look better after scaling up? Or is Lancelot inconsistent and just for Oxygen it does the right thing and picks up a bigger size to scale down instead of smaller to scale up
Should I report a bug to Ivan Čukić (the awesome dude who wrote Lancelot)?
I wonder, if Reflektions-KDE4 had SVG version of all icons included, would that solve the problem? I mean: Lancelot could pick only vectors to scale? Needless to say, having this great set in vector format would a big advantage anyway..
