Following is a detailed description on how the KnotPlot script was used to generate the files on this page. Example shown is for letter size paper. See the note (right) about printing to A4 paper. If you're only generating an EPS file for inclusion in another document, then you don't need to worry about setting the pagesize.
Run KnotPlot in non-graphics mode to generate the EPS file.
knotplot -nog < psm_eofill2.kps
One could instead run KnotPlot in graphics mode and enter the following command into the KnotPlot Command Window
We now have the file psm_eofill2.eps which could be printed directly on a PostScript printer. For printing to a non-PostScript printer, generate a PDF file psm_eofill2.pdf from the EPS file psm_eofill2.eps using Ghostscript.
# Note: enter the following three lines on one command line gs -dCompatibilityLevel=1.3 -q -dNOPAUSE -dBATCH -sPAPERSIZE=letter -sDEVICE=pdfwrite -sOutputFile=psm_eofill2.pdf -c .setpdfwrite -f psm_eofill2.eps
The remainder of this example shows how the preview image seen above was created. This is useful for including an image on a web page or in a presentation. Printing the EPS or PDF file will give much higher quality than printing the preview image. These files, psm_eofill2.eps and psm_eofill2.pdf, as well as their counterparts for A4 paper, psm_eofill2_a4.eps and psm_eofill2_a4.pdf, can be downloaded using the links in the right hand panel on this page.
# run Ghostscript to generate a temporary PPM file # Note: enter the following two lines on one command line gs -q -dNOPAUSE -dBATCH -sPAPERSIZE=letter -sDEVICE=ppmraw -sOutputFile=psm_eofill2.ppm -r200 -f psm_eofill2.eps # scale it down using ImageMagick convert command convert -resize 600x psm_eofill2.ppm psm_eofill2S.ppm # reduce the number of distinct colours and create the gif convert -colors 32 psm_eofill2S.ppm psm_eofill2.gif # delete temporary files /bin/rm psm_eofill2.ppm psm_eofill2S.ppm
KnotPlot script that generated the Encapsulated PostScript (EPS) file:
% KnotPlot script: psm_eofill2.kps

% example of a checkerboard colouring
refine 5 % looks better with this
psoption fancy eofill 1 1 1
psoption fancy bbox 0 0 0
psoption fancy draw 20 % draw bbox and checkerboard
% End of KnotPlot script
This script generates a EPS file (download below) suitable for printing on letter size paper. For printing on A4 size paper, use the command psop pagesize a4 prior to the psout command.

The PDF files and the preview image seen on this page were generated from the EPS files using Ghostscript (details in left panel on this page).
