- I DESPARATELY need to convert 16-bit grayscale tiff images to 8-bit for use in a
- variety of drawing and presentation programs. It seems that Leffler's libtiff tools, pbmplus, UCSD,
- Image Alchemy, MIFF tools, and the UTAH converters all accept as input only 8-bit
- grayscale images. I realize that converting from 16 -> 8 loses dynamic range but this is a loss
- I must accept in order to view the images in any standard package. I am not a graphics programmer
- so I cannot easily modify tiffcp or tifftopnm myself (I can figure out the place in the code to do this,
- but haven't a clue about how to ultimately manipulate the bits and the header information to
- produce a useable file). Any help would be greatly appreciated.
