Hi Sam,

Hmm, It might be usable. I'll have to investigate. Thanks.

What about using a graph plotting program? I just tried gnuplot and it seems to be able to generates SVG output these days. Some of the demo's at:

http://gnuplot.sourceforge.net/demo/surface1.html

look similar to what you could want to do. I just tried using the following script:

set terminal svg set output "surface.svg" set samples 51, 51 set isosamples 21, 21 set yrange [ -1.00000 : 1.00000 ] noreverse nowriteback set zrange [ -1.00000 : 1.00000 ] noreverse nowriteback splot [x=-3:3] [y=-3:3] sin(x) * cos(y)

and it seemed to produce something that inkscape could read, with the surface as a seperate path that could be copied into another document. Chosing a good function and viewpoint would be "fun" with gnuplot, but it could work.

Thanks Shawn,

It is not exactly what I imagined. Have a look at the attached images. They are more contour like - whatever that is :-)

Hi all,

I have a small web site (http://rcp-company.com) where I have inherited

So if anybody knows how to do this, then plase let me know.

Here are regular contour lines. I not sure how to randomize them.

Do you want to copy the images or just create something similar?

To create a close copy of main_epilogue.gif:

* Load the GIF.

* Create a new layer above it.

* Use the Bezier tool to create a spline along the top contour. Spline is the official name for a Bezier curve. It is also called a B-spline.

* Use the Edit Nodes tool to adjust the spline to match. One of the advantages of vector graphics is that you can always tweak at any time.

* Select it, copy and paste.

* Align the new spline with the next line down.

* Use the Edit Node tool to adjust it.

* Repeat until all "horizontal" lines are done. Usually it's better if you copy and paste the last line you worked on, rather than just pasting the first over and over.

* Do the same thing for the "vertical" lines.

* Delete the layer with the GIF.

You can try to do the same with header_bg.jpg but the problem is seeing the white lines in the light background. I would first try to make them black using Photoshop or GIMP before I tried to creating splines for them.

Hi Shawn,

You method worked. I now have a contour surface I can use to create a new set of images for my web site.

Thanks.
