base.cfg (accessible from Menu Edit|Configure|base) now contains a new global setting GL2Backend which is default to 0.
NB. GL2Backend: backend for gl2 emulation NB. 0 system default (cairo) NB. 1 cairo NB. 2 gtkpixmap NB. 3 gdiplus (windows only) NB. GL2Backend=: 0 default is 0 (cairo) which is quite good but can be slow. On setting it to 2 (gtkpixmap) , then plot and other packages depending on gl2 may be 100% faster. gdiplus (most gl2 draw primitives implemented by Ric, thanks Ric) is available in windows only, which can be a bit faster than pixmap. Setting it to 3 in linux is not an error but will fall back to 0 (default cairo). There are still some issues in gdiplus backend including bold or italic fonts. Please test and report if there will be other issues. A way is run plot demo in J602 and compare the outcome with that running in 701 load '~addons/demos/plot/run.ijs' -- regards, ==================================================== GPG key 1024D/4434BAB3 2008-08-24 gpg --keyserver subkeys.pgp.net --recv-keys 4434BAB3 ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
