Hi Greg and Paul, I tried several things, but I did not succeed: * I could not find the library(EBImage) on CRAN in Austria to open an png image in R. * I could not import the image via pixmap (read.pnm) as described on http://wiki.r-project.org/rwiki/doku.php?id=tips:graphics-misc:translucency because my GIMP cannot write pnm format. * I could not manage use the 'grImport' package to trace the svg:
readPicture("Aries.svg")
Fehler in readPicture("Aries.svg") :
Version mismatch: RGML file needs to be recreated with PostScriptTrace()
Yep, you need to convert to PostScript (ImageMagick or InkScape ought to do it) before you can import it. See http://www.stat.auckland.ac.nz/~paul/R/grImport/import.pdf for a thorough description of how the package works. Paul
* I gave up modifiying the svg code from wikipedia to make it an R array (structure) as you greg described it above. If you have any hint for me please let me know. I am willing to contribute something to TeachingDemos (although I am not sure if this is not a license problem as I trace the (public domain) images from wikimedia. Otherwise I am happy with the Hershey fonts so far. Thomas
