16 pbmto4425 displays PBM format images on an AT&T 4425 ASCII terminal
17 using that terminal's mosaic graphics character set. The program
18 should also work with other VT100-like terminals with mosaic graphics
19 character sets such as the C. Itoh CIT-101, but it has not yet been
20 tested on terminals other than the 4425.
21
22 Pbmto4425 puts the terminal into 132 column mode to achieve the maxi‐
23 mum resolution of the terminal. In this mode the terminal has a reso‐
24 lution of 264 columns by 69 rows. The pixels have an aspect ratio of
25 1:2.6, therefore an image should be processed before being displayed in
26 a manner such as this:

29 % pamscale -xscale 2.6 pamfile \
30 | pamscale -xysize 264 69 \
31 | ppmtopgm \
