Dezoomify

Ruby + ImageMagick script to stitch Zoomify Viewer tiles into a single image at the maximum zoom level.

Usage

Give the URL of a page that contains the Zoomify Flash viewer, e.g.:

./dezoomify.rb 'http://www.christies.com/lotfinder/ZoomImage.aspx?image=/LotFinderImages/D52792/D5279274'

The scenario:

We are writing a digital textbook-reading app.
Most of the time you have a "basic" license for your textbook, but one (and only one) of your computers can request an "enhanced" license.
You can only print from the computer with the enhanced license.

The problem statement:

Program Database (PDB) File Format

The PDB file format is a compound file. It is composed of numbered data streams, each of which stores some predefined information about the target program. For example, one stream appears to contain a list of symbol names, while another describes the code and data sections used by the linker.

A special stream, the root stream, contains all the information necessary to locate the other streams within the file.

All numbers are encoded in little-endian format.

Credit to http://www.informit.com/articles/article.aspx?p=22685 for reverse-engineering an older version of the PDB format, which helped considerably.
