[Plplot-devel] Recent CVS changes

[Alan W. I. <ir...@be...>]

(1) pbm.c driver changes donated by Gary Bishop which allow you to change
the size and background color.  I have only done minimalist testing of these
changes so if any of you have an interest in the pbm driver, please give
this a hammering.

(2) xw17.py donated by Gary Bishop.  This gives equivalent of x17c, but
the xw17.py results are different each time (and different from the
constant x17c results) because the python random generator is different
from drand48 used in x17c.c.  Also, the x17c.c result uses a constant
seed while the python random number generator picks a seed depending on
the time of day.

(3) plmodule.c changes to implement python wrappers for plstripa, plstripc,
and plstripd.  These are required for xw17.py to work.

I did this last change by hand, but that may be the last time I do so. Gary
has used an entirely different swig-based approach for generating the python
wrappers which I intend to evaluate soon.  Similar in spirit to the tcl
interface, I may want to adapt his approach to a semi-automated method where
swig would generate all the generic python wrappers.  These would be
supplemented by hand-built wrappers for the difficult cases.  I believe such
a semi-automated approach is a lot easier to maintain than the current
plmodule.c which is completely built by hand (and where there is presumably
key functionality such as the recently discovered plstrip[acd] still missing
from the resulting plplot API for python).
