Just working on SVG export. There are more ways how to handle labels -- but no perfect one. 1) Use SVG fonts (embedded). These would be supplied with Therion (converted from TeX fonts used in PDF output). pros: the SVG map will be nearly identical to PDF cons: large file (fonts are embedded) SVG fonts are unhinted hard to edit in drawing programs hard to add new font 2) Use system fonts pros: small file (fonts are not embedded) full unicode support (if unicode fonts are installed) cons: platform dependent problems with precise alignment of labels metapost can't calculate frames (e.g. for passage height) nor clipping paths 3) Use system fonts but supply font metrics for metapost pros: nice output with clipping paths, alignment etc. cons: unportable hard to generate metrics for the regular user 4) Use bitmaps as labels cons: unscalable would require additional convertor uneditable I'd like to get your comments, hints or suggestions, which one to prefer. I'd say the 1st one. Cheers, Martin
