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