Option Summary
]
Use the
display
program to display an image or image sequence on any X server.  See
../www/command-line-processing.html
Command Line Processing
for advice on how to structure your
display
command or see below for example usages of the command.
Example Usage
We list a few examples of the
display
command here to illustrate its usefulness and ease of use.  To get started, lets display an image in the JPEG format:
display rose.jpg
To tile a slate texture onto the root window, use:
display -size 1280x1024 -window root slate.png
To display a visual image directory of all your JPEG images, use:
display ???vid:*.jpg???
You can find additional examples of using
display
