<H2>DESCRIPTION</H2>
|
|
|
|
Reads a portable anymap as input.
|
|
Replicates its pixels
|
|
<I>N</I>
|
|
|
|
times, and produces a portable anymap as output.
|
|
<A NAME="ixAAC"></A>
|
|
<P>
|
|
|
|
<I>pnmenlarge</I>
|
|
|
|
can only enlarge by integer factors.
|
|
The slower but more general
|
|
<I>pnmscale</I>
|
|
|
|
<A NAME="ixAAD"></A>
|
|
can enlarge or reduce by arbitrary
|
|
factors, and
|
|
<I>pbmreduce</I>
|
|
|
|
<A NAME="ixAAE"></A>
|
|
can reduce by integer factors, but only for bitmaps.
|
|
<P>
|
|
|
|
If you enlarge by a factor of 3 or more, you should probably add a
|
|
<I>pnmsmooth</I>
|
|
|
|
<A NAME="ixAAF"></A>
|
|
step; otherwise, you can see the original pixels in the resulting image.
