Can anyone give me pointers on methods of handling dual font representations in raster and vector? For example, is there available any software or algorithms for converting a raster font definition into an efficient vector representation? Does anyone have any experience in this problem area? If so, how have you handled the problem? We would like to use raster font definitions because of their flexibility in defining unique fonts and their speed in rendering text on raster displays. However, not all software and/or hardware we must interface with can support raster text rendering. The approach we are probably going to take is to define fonts in raster and associate with them a vector representation. The vector representation could be manually defined or generated from the raster definition. Device drivers would access the definition they need for the particular device. If one representation or the other is missing, then any attempt to use a device that requires the missing representation would fail. Any comments on this? Any suggestions for alternatives? Respond by e-mail and I will summarize for the net, if interest warrants it. Thanks in advance, -- John McNally GE/Calma 9805 Scranton Rd.

Organization : California Institute of Technology Keywords: text fonts, raster, vector, Breshenheim (sp??) algorithms . I am also extremely interested in this subject, especially converting raster fonts to vector fonts. Also, could someone please send me the Breshenheim (spelling?) algorithm for rasterizing circles? Any advice and information is greatly appreciated. Curtis
