Hi, as some of you may know, there is an mplib project .. last week taco and spent quite some time on exploring the integration in luatex (and therefore mkiv) experiments with loadiing the format, processing graphics and conversion to pdf show a throughput of less than 0.001 seconds per graphic; a usual we did much timing and although experimental, the code is already pretty okay, just to give an idea: mkiv lua stats : metapost processing time - 6.834 seconds (loading: 0.014 seconds, execution: 1.474 seconds, n: 15000) indeed, that's 15K graphics in 7 seconds. so, the next couple of months i'll start providing an adapted mp handling mechanisms. among the possible options are - extensions based on pre/postscripts (instead of specials) - multiple mp engines (\startuseMPgraphic[metafun]{name} and such) so, if you have specific wishes ... now is the time to let them know Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | fax: 038 477 53 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------
