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
