 PBMTO4425(1)                                         PBMTO4425(1)
 
 
 
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 termi­
        nals 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
        manner such as this:
 
               % pnmscale -xscale 2.6 pnmfile \
                      | pnmscale -xysize 264 69 \
                      | ppmtopgm \
                      | pgmtopbm \
                      | pbmto4425
