I have read Drawing a smiley face, part 3 [1] How do I do shaded hatching like in the image at wikipedia.org[2] ? [1] http://wiki.evilmadscience.com/Drawing_a_smiley_face,_part_3 [2] http://en.wikipedia.org/wiki/Hatching

There is such a program (of course), and it can even export SVG. It's called R, and apart from the fact it's a statistical programming environment which has a steep learning curve, on the bright side it's open source and therefore available. The graphics engine was developed at the Bell Laboratories and it is widely viewed as having the most flexible (end beautiful) graphics around. Just google for R, the first link will take you there.

Sorry to be slow, I have been abroad until today. Erhm... I'm not exactly a specialist in whatever you want to obtain. Should you give me an example of an "natural looking hatchings", I'll try and see if R can produce it.

Otherwise you are right, I thought you meant hatchings used for monochrome pie charts, but R can basically produce anything you want (including, for example, SVG geographical maps). Hth, Adrian

Sent: Monday, 12 September 2011 7:57 PM If you know of any program that can (semi-)automatically create those kinds of hatchings, I'd love to know. As for importing from the gimp, if it's just a bitmap it will still be just a bitmap when imported. You might have some luck with tracing such bitmaps though (so if you manage to get a nice bitmap with a hatching, you be able to import it and get a decent trace of it so that you alter it in Inkscape).

Well a lot are "not that good", another is that (many) are made for shading 3D models (rather than helping with 2D drawing). Although there is bound to be something out there that uses one of these algorithms, I would expect it more in the 3D modelling area.
