>It should be quite a simple job to adjust the black point for a bitmap to make any shade of grey truly black. It you have a bitmap editor with a levels control, you can adjust the end points of the black-white range of image.
My experience on many occasions is that the transformation by Therion makes the resulting image appear grey. I don't think it is a fault of the original image (but I have not ever looked into it in detail). Bruce -------------- next part -------------- An HTML attachment was scrubbed...
