bw-ps [-e] [-c] [-L] [-s input_squaresize] [-w input_width] [-n input_height] [-S inches_square] [-W inches_width] [-N inches_height] [infile.bw] > outfile.ps
By default the output PostScript image size is 6.75 inches. The -c option will center it on a 8.5 x 11 inch page. If a different output size is desired, -S -W and -N can be used to set the size in inches analogous to the input parameters. Finally, -L selects landscape mode, i.e. rotates the output image by ninety degrees.
Encapsulated PostScript files can be generated via -e.
Produces a 6.75 inch PostScript file from an 512 x 512 input image and centers it on an 8.5 x 11 inch page.
bw-ps -e -w 1024 -n 768 image.bw > image.ps
Takes the file image.bw which has the dimensions of 1024 pixels wide by 768 pixels high, and produces an Encapsulated Postscript version of it.
bw-ps -L -c -S 5.2 < image.bw > image.px
Makes a PostScript file of the (assumed 512 square) image, with the output image 5.2 inches square, in landscape mode, centered on an 8.5 x 11 inch page.
