Why the metapost not updated the value of text variables that are generated inside luacode environment?
In the code below, If I have \startitemize[columns,two] then metapost draw:
1. \Bolha[size=6cm]{text1}{text2}{text3}, 2. and four \Bolha[size=4cm]{text1}{text2}{text3}, but text1, text2 and text3 is not updated in every call;
Use useMPgraphic instead of uniqueMPgraphic.
uniqueMPgraphic recomputes the graphic only when the dimensions of figure has changed; otherwise, it reuses the previously drawn graphic. This behavior was useful for drawing page-backgrounds etc in MkII where calling metapost was slow.
not only dimensions, also the overlay related colors (and if needed one can extend the hash used) .. an other advantage (also in mkiv) is that reuse also makes the pdf file smaller Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | voip: 087 875 68 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------
