initialized stuff like the photometric and samplesperpixel tags and such somewhere in the code. Sorry I cannot seem to be more helpful.
the problem, it turns out, is that none of the applications i was trying to read the image with handle tiled TIFF correctly. Photoshop can, but not much else.
Does GraphicsMagick not work for you?
