Why does it resale the image?

I sent a 640x411 image and got back a 800x514

Also an area of solid black turned into cyan and magenta. (The image I tried was http://i42.tinypic.com/169lppj.jpg - and yes I know it's not a whiteboard, but it looks like one.)

Sorry, I'm rescaling the image right now to roughly 800x600 to keep down on the memory usage of the process. Based on what I'm seeing today I think I can raise the maximum picture size and not rescale if it's within that size. Thanks for giving it a try.

The last time I did something like this, I made a point to never scale upwards to the target size.
