Dir Sir,

We are using ImageMagick-6.5.9-10.
When we convert with -resize option, we find the following problems:

1) % convert -resize 48x14 f1.pgm f2.pgm
   % display f2.pgm

   When display command displays the converted image, f2.pgm, the
image cannot be displayed well.

2)  % convert -resize 48x14 -compress none f1.pgm feep3.pgm
    % display f3.pgm

   When display command displays the converted image, f3.pgm, 
   the image is blurred.


f1.pgm is as follows:

% cat f1.pgm 
P2
24 7
