Image Map Reduce JAR
A custom jar application that contains a map function that takes images and converts them to other formats and sizes.
Instead of using convert this Custom jar uses JAI. This tool is meant for servers that do not support
convert or other tools.
See FileStreamMapReduce.jar to use convert or ffmpeg.
It supports the following parameters:
-maxWidth=640
-maxHeight=480
-maintainAspectRatio=false
-extension=JPEG
Codecs supported by JAI:

BMP, JPEG, GIF, JPEG, PNG, PNM, TIFF, WBMP, FlashPix.
Purchase this JAR for now for only $20.

Would it be possible to see the source code for this jar file? I’m thinking about using an hadoop cluster to split multi-page TIF files into single pages.
Selling the source code for the jars for $100.
It uses JAI in the image example for scaling etc. So anything you know how to do with JAI you can do.
Split up multipage TIFF files.
