magick display [options] input-file


The display program is a member of the ImageMagick(1) suite of tools.  Use it to display an image or image sequence on any X server.

For more information about the display command, point your browser to file:///usr/share/doc/ImageMagick-7/www/display.html or https://imagemagick.org/script/display.php.

In addition to those listed above, you can specify these standard X resources as command line options:  -background, -bordercolor, -borderwidth, -font, -foreground, -iconGeometry, -iconic, -mattecolor, -name, -shared-memory, -usePixmap, or -title.

By default, the image format of `file' is determined by its magic number.  To specify a particular image format, precede the filename with an image format name and a colon (i.e. ps:image) or specify the image type as the filename suffix (i.e. image.ps).  Specify 'file' as '-' for standard input or output.

 1    press to map or unmap the Command widget
 2    press and drag to magnify a region of an image
 3    press to load an image from a visual image directory


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