NAME

       pbmto4425 - Display PBM images on an AT&T 4425 terminal

SYNOPSIS

       pbmto4425 [pbmfile]

DESCRIPTION

       Pbmto4425  displays  PBM  format  images on an AT&T 4425 ASCII terminal
       using that terminal's  mosaic  graphics  character  set.   The  program
       should  also  work with other VT100-like terminals with mosaic graphics
       character sets such as the C. Itoh CIT-101, but it  has  not  yet  been
       tested on terminals other than the 4425.

       Pbmto4425 puts the terminal into 132 column mode to achieve the maximum
       resolution of the terminal.  In this mode the terminal has a resolution
       of  264  columns by 69 rows.  The pixels have an aspect ratio of 1:2.6,
       therefore an image should be processed before being displayed in a man-
       ner such as this:

              % pnmscale -xscale 2.6 pnmfile \
                     | pnmscale -xysize 264 69 \
                     | ppmtopgm \
                     | pgmtopbm \
                     | pbmto4425
