On Scale2x and hosting tilesets on NetHackWiki

It looks at first glance like this Scale2x is at least trying to do some smoothing on the interpolated pixels. I haven't looked at it closely enough to say exactly what it's doing. I should note, however, that the DevTeam's tileset uses only 16 colors, and one that has been scaled in this fashion will likely use more. While this won't be a problem on any remotely modern hardware, someone still using a rusted-out 386 might possibly get unexpected results.

Also, different GUIs expect their tilesets in different formats -- Win32 uses BMP, X11 uses XPM, Qt can use PNG directly, I don't know what GEM and Amiga use. I'm not opposed in principle to hosting tilesets on NetHackWiki, but if we're going to do it, we'll probably want them to be PNGs, since those are well-compressed without loss. It might be well to have a page, or a section under Tileset, on how to convert PNGs to other formats. (Would the Lords and Ladies of Wikia get on our case if someone uploaded Absurd128? The PNG is about 15 MB, and the BMP more than 50.)--Ray Chason 03:27, 21 December 2008 (UTC)

Just checked with the help wiki and it seems we're limited to 5 MB per file, of whatever type, and that for images we can only use GIF, PNG, JPEG and SVG. So no, you can't have Absurd128 on WikiHack. Not yours.--Ray Chason 03:40, 21 December 2008 (UTC)
A closer look at Scale2x shows that it doesn't introduce new colors to the image. It was sort of *meant* to run on those rusty old 386es, or at least sleek new dual-core Xeons emulating rusty old 386es.--Ray Chason 04:36, 21 December 2008 (UTC)
Scale2x does not add colors, so the 32x32 version added still has the same number of colors; 20x20, 20x30 and 24x24 are downscaled after a scale2x upscale though, so they do introduce new colors. I add a (+1) vote for the PNG format, as it's flexible enough to accommodate any number of colors and compression rate is great when application is well built (Photoshop users might want to use a tool like optipng to "fix" these PNG).

Now that we control the wiki ourselves, go ahead and upload it! Tjr 20:17, 11 November 2010 (UTC)
I've de-linkified Wikia. --Tjr 21:55, 27 January 2011 (UTC)
