Writes MetaPost code for the labels to
out_stream
. It is called inPicture::output()
(see Picture Reference; Outputting). Users should never need to call this function directly.When
Picture::output()
is invoked, the MetaPost code forLabels
is written toout_stream
after the code for the drawing and filling commands. This prevents theLabels
from being covered up. However, they can still be covered by otherLabels
, or byShapes
orLabels
from subsequent invocations ofPicture::output()
within the same figure (see I/O Functions, for descriptions ofbeginfig() and endfig()
).
