> Yes, the enlarged BeOS icons look weird -- of course they do, they are
32x32 bitmaps scaled up to 128x128. There is no magical scaling algorithm
(that I have the code for anyway) that will turn 32x32 bitmaps into
128x128 bitmaps without sacrificing quality. That is one of the reasons
why stippi developed HVIF in the first place! I have hope that someday we
can use the techniques in the "Depixelizing Pixel Art" paper from
Microsoft Research to scale BeOS icons up better, but that is all I have
right now, hope, no code.

I may have used the wrong terminology here. I know that the BeOS icons at
128x128 are going to look odd. I was questioning whether _having_
scaled/enlarged BeOS icons was worth while at all. Why highlight old
pixelated icons, especailly ones for which we already have HVIF icons?
The idea of "Depixelating" sounds neat and I hope you have time to
investigate it. Though, I realize that your current solution may be good,
I just would rather not have to use the old BeOS icon.

> I can break the patch up into 2 parts, but let me first say that scaling
up the BeOS icons using bilinear scaling is going to look /even worse/
then it does using scale3x/scale4x. I know this because I compared the 2
closely when I implemented scale2x for 64x64 icons. You can see the
different between scale2x and bilinear scaling for 64x64 BeOS icons by
looking at the images attached to #7130.

Again, I may not have been clear in my question and used the wrong term.
I suggested that the patch be broken up so that the Haiku part could be
applied quickly. It would then allow you, or anyone else, to see _if_
there was another solution for the BeOS icons, such as as Axel's about
enlarging the pixels.

> Mac OS X uses a slider to adjust Finder icon sizes. Windows 7 puts the
options in the View menu of Explorer like Haiku, but has fewer options
[http://www.sevenforums.com/tutorials/3916-icon-size-change-windows-
explorer-window.html Windows 7 icon size]. I like the slider, it
accommodates more sizes.

Thanks for the link. I definitely like the slider option. One of the few
places where I think a slider would be ideal. It would de-clutter the
menu, which is good.
