Hi Fred – Thanks for the tip about "imagener" (item #13 in the http://www.langalist.com/Plus/newsletters/2003/2003-03-27plus.asp issue). I have been using a "Genuine Fractals" plug-in (from http://www.lizardtech.com/ ) for quite a while in Paint Shop Pro. It’s actually a Photoshop plug-in that works with most any Photoshop plug-in compatible program like Paint Shop Pro.
The way it works is it uses "fractal" algorithms to blow up small graphics to larger sizes with little or no loss in quality. I’ve used it many times to take 200×200 pixel images up to 1000×1000 or bigger with excellent results. The resulting "fractal-ized" file is very small and only expands in size when you "save as.." to save it as a different file format (it opens in it’s native format inside Paint Shop Pro or Photoshop similar to JPEG, TIFF, etc. except when it first "samples" an image.
There’s a free trial version and a few paid versions ranging in price from $40 to $300 depending on your output file size needs. I do graphics work up to about 8.5×11" (mostly photos) and find the LE version works fine for me.– Kevin Talbot
All these tools are amazing in how they can fudge the missing detail and create a decent-looking enlargement— far better looking than the usual blocky-pixel mess you get when you enlarge a small image by simple rescaling. Nice!...
