# pbmto4425(1)

Display PBM images on an AT&T 4425 terminal

## NAME

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

## SYNOPSIS

**pbmto4425** \[*pbmfile*\]

## DESCRIPTION

This program is part of **Netpbm**(1) .

**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 manner such as this:

```
% pamscale -xscale 2.6 pamfile \
    | pamscale -xysize 264 69 \
    | ppmtopgm \
    | pamditherbw \
    | pbmto4425
```

## OPTIONS

There are no command line options defined specifically for **pbmto4425**, but it recognizes the options common to all programs based on libnetpbm (See \
