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. |
