Back in the early 1990s Ray Dream created a cool image enhancement utility called Jag II. The program would help remove jagged edges from images.
This is from their press release from April 13, 1993:
JAG II features a completely revised edge detection algorithm which finds the jagged edges in an image -- whether the image is black and white, eight-, 16-, 24- or 32-bit color -- and compares them to the background. JAG II determines whether to use the original technique of adding intermediate colors to blend the edges or to take advantage of the new resolution-boosting algorithm to maintain the document's color palette and smooth the jagged edges through increased resolution. This ability to maintain the color palette is a vital tool when working with monochrome images on laser printers which don't support the use of the intermediate color (gray), or when a restricted color palette is in use. The added resolution allows a crisp, clear image at any size.
One of the things that I liked about was the design of cool splash screen.
A problem with JAG II is that it doesn't have any support for JPEG images. It supported opening PICT, Tiff, Photoshop 2.0, MacPaint, Quicktime Movie, AVI, Autodesk Animator, DV, Animated GIF, SMIL, Movie, Pictures, PICS and Graphic Files.
If you have a lot of images, you could use the Batch Processing. However, the application doesn't always do a great job. Check out the rendering of this graphic file from 1.0.4
Ray Dream was purchased by Fractal Design in 1997.
