[Added] Pixel Art Scaling Algorithms

Post by peterburk »

I've been a long-time user of GraphicConverter, with a paid version of 3.6.1 on a CD!

I just went through my old computer collection, copying many old software & MacFormat CDs, SCSI & JAZ disks, HD & DD & 5.25" floppies all onto my Retina MacBook Pro. That included a collection of 133,000 icons that I made using Icon Archiver 4.0. I exported those as folders, then converted them to icns and then to png. Please email me (peterburk@gmail.com) if you're interested in the collection! I also realised that I should go through all the disk images and search for more icons from the colour Macintosh pre-OS X era (1987-2002). I think they'd work well on mobile devices, which use an icon-driven GUI.

While reading about pixel art on Wikipedia, I saw a link to Pixel art scaling algorithms.

Please could some of these algorithms be included in a new version of GraphicConverter?
I'd really like to scale up these old icons.

I have seen some of these algorithms in MAME. There are probably few games where this works well but they would be awesome for upscaling icons!
