137 width, -font, -foreground, -iconGeometry, -iconic, -mattecolor, -name,
138 -shared-memory, -usePixmap, or -title.
139 By default, the image format of `file' is determined by its magic num‐
141 ber. To specify a particular image format, precede the filename with
142 an image format name and a colon (i.e. ps:image) or specify the image
143 type as the filename suffix (i.e. image.ps). Specify 'file' as '-' for
144 standard input or output.

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