Thanks, but cc does not seem to import my png files. I do not have the
inclination to dig further, since i think I can get around the problem
within openscad itself, using offsets on the png surface file(translated

If you have a high-resolution image, I would suggest tracing.
A free program which includes this feature is Carbide Create v6:

Then, once you have a vector image you can adjust it as needed and
export to an SVG which can be imported into OpenSCAD.

Subject: [OpenSCAD] OT - PNG jaggies
In the past, I've drawn icons and the like, by using a felt-tip pen,
at a large size, and using a desktop scanner and reducing the size in
image editing software. This reduces errors and gives the impression
of smoothing the ragged edges when printed at the final size. However,
the same technique does not seem to work for openscad, which seems to
pick up the individual pixels from the scan resolution, giving a very
complex outline for png's. Smoothing, the usual visual way, simply
blurs the outline, and reverting to black and white, returns it to
more or less to the original resolution. Anyone know of any smoothing
software that will actually smooth out the jagged edges?
An example of an image is attached, which needs to be about 24 units
between leaf tips.
