Drunk cannot output 16bit images

Hi,

Thanks to all developers for the wonderful MicMac toolset!

I usually take photos with my Canon PowerShot SX260 HS. Thanks to CHDK I can safe raw images in DNG format and then dcraw enables me to turn those into bitmaps with 8 or 16 bits colour depth. At lowest focal length the distortions in the picture are basically unbearable, but Drunk does a great job in correcting those. This works nicely with 8 bits colour depth, but with a 16 bit tiff I get this error:

C:\Photogrammetrie\eckePulverturm\raw>mm3d Drunk CRW_1537.tiff Orientiert2000 Out=entzerrt/entzerrt

Bye  (press enter)

As the error occurs during writing the bitmap, maybe this is easy to fix / extend for 16 bit output?

Thanks for your help, Martin

Maybe I could add a force8bit (F8B) and a FG (force gray) options to Drunk (like in scaleIm) and set F8B default to "true" in order to keep backward compatibility with existing binaries calling Drunk. Does it look an acceptable solution?

Sounds perfect to me as a user!
