ImageMagick Display Command-line Tool

Use the display program to display an image or image sequence on any X server. See 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'

The display program defaults to the X screen resolution. To display vecotr formats at their intended size, override the default resolution:

$ display -density 72 drawing.svg

You can find additional examples of using display in Graphics from the Command Line. Further discussion is available in More Graphics from the Command Line and Examples of ImageMagick Usage.
