Re: Convert Tif to PNG

I believe that your tif is not created correctly. Many viewers won't 
even open it. GraphicConvert (Mac) seems to handle it. But IM gives 
errors (though it creates  the image, but it is black):

  convert 110316195160_0.tif -colorspace rgb 110316195160_0.png
convert: Improper JPEG sampling factors 2,2
Apparently should be 1,1.. `JPEGPreDecode' @ warning/tiff.c/TIFFWarnings/706.
convert: Cannot honour JPEG sampling factors that exceed those 
specified.. `JPEGPreDecode' @ error/tiff.c/TIFFErrors/496.


Note that PNG does not support CMYK format and your tiff is CMYK. So 
it needs to be converted to RGB by -colorspace or by profiles.
