# The jiv Program

## Synopsis

`jiv` [options] [file1 file2 ...]

## Description

The jiv command displays an image. Basic pan and zoom functionality is provided. Components of an image may be viewed individually. Color components may also be viewed together as a composite image. At present, the jiv image viewer has only trivial support for color. It recognizes RGB and YCbCr color spaces, but does not use tone reproduction curves and the like in order to accurately reproduce color. For basic testing purposes, however, the color reproduction should suffice.

## Options

The following options are supported:

- `--help`
  - Print help information and exit.
- `--version`
  - Display the version information and exit.
- `--wait $n`
  - Automatically step from one image to the next, pausing for `$n` seconds in between.
- `--loop`
  - Repeatedly cycle through the specified images.
- `--memory-limit $n`
  - Set the memory limit to `$n` bytes.
- `--debug-level $level`
  - Set the debug level to `$level`.
