Morphing images in OS X Apps
This weekend, I was looking for a way to morph (change) one image into another to show the "before and after" images for a small home remodeling project we just completed. At first, I was experimenting with the various transitions in iMovie, but wasn't satisfied with the results. A little digging on the web found MorphX, a slick piece of freeware by Martin Wennerberg which does the job amazingly well.

The interface is elegant, powerful, and yet easy to use. Simply drag in two images, mark out identical regions in each image for the program to work with, and then specify the number of morphing steps to be calculated. You can even set the morphing properties of each line or region independently from all the others, if you wish. and then wait a while ... perhaps a long while if you specified a large number of areas and steps in a complex image. I was using 100 steps, and my G4/733 took anywere from 30 to 60 minutes to calculate all the in-between steps.

Once done, you can (with QuickTime Pro, at least, I'm not sure abou the free version) save the resulting collection of images as a movie. I got the best results by then exporting this saved movie using a faster framerate; I used 10 frames per second during the MorphX image creation, but then set it to 30 frames per second on the QuickTime export. The resulting movie played back smoothly, making a nice transition from the "pre" image to the "post" image.

After spending quite a few hours with MorphX this weekend, it's now this week's Pick of the Week!
