Subject: Re: bad rendering of level 2 images
References:  <19981207114834.23438@k332.feld.cvut.cz>
Sender: owner-tiff@olympiakos.com

The differences between Level 1 and Level 2 output from tiff2ps have nothing
to do with g4 encoding.  The problem is that the Level 2 output uses the
"Interpolate" option in the images.  This option invokes
implementation-dependent smoothing algorithms that are not defined in the
Adobe manual and should definitely not be used on high-resolution
black-and-white images.

Since other people have complained about this, I am planning to disable the
Interpolate function on black-and-white images that are close to the device
resolution.
