squarezoom-random

Run make && ./squarezoom-random/squarezoom-random -R -w 1024 -h 1024 (or other powers of two) to build and run in a window.

squarezoom-image

Run `make && ./squarezoom-image/squarezoom-image -R image.jpg (or other powers of two) to build and run in a window.

To build without the FreeImage dependency, instead run SQUAREZOOM_NO_FREEIMAGE=1 make. This means you will only be able to read and write images in the Netpbm PAM format. You can use ImageMagick's convert utility to convert from and to this format.
