Subject: metapost not adding picture
Date: Sun, 9 Oct 2011 20:01:43 +0000 [thread overview]
Message-ID: <7DB87D17-D0EF-4C28-94A9-F9595B89F603@uva.nl> (raw)
I have this question on the implementation of metapost.
The following program ends in an error:
\startMPpage
picture v;
draw origin--(1cm,1cm);
v = currentpicture;
clearit;
draw (1cm,0)--(0,1cm);
currentpicture := currentpicture + v;
\stopMPpage
The error is: ! Not implemented: (picture)+(picture).
Yet Knuth's metafont book in Chapter 13 tells me, quote: "Pictures can be added or subtracted;"
Is the current metafont implementation lacking this feature? Will it be implemented in the near future?
