cairo / pango
- Hi Steve,
It's not needed to post this to the ploticus group (unless you
want to). I couldn't find your personal email.
I'm wondering if cairo / pango (CP) might be a better choice
than GD for programming ploticus. I've used GD for a long time,
in a different software (nothing to do with ploticus), for
drawing maps. Recently, I've been changing the source code
to use CP, to add pdf maps. The vector graphics gives so
much better detail. I'm getting the hang of CP, and like
them a lot. I'm in the middle of switching the old png
mapping to also use CP. At this point, I like CP better
than GD. I'm pretty sure it has more capacity than GD.
I use ploticus for auto-generating charts. I don't know if
there is any clamor for pdf in ploticus. I would probably
use it if available. On the other hand, I would have to
think of how to fit wide or long charts onto pdf. A good
thing about the maps is the size is predictable, so they
always fit on one pdf page, and look great when printed.
Besides the pdf, the only things I ever wanted different
in ploticus were *** labels not overlap on pie charts,
*** X axis spacing tighter on bar charts, *** not have
to fiddle with some fudge factors to make auto-generated
charts always look good. I'm thinking these and other
things might be more doable using CP.
ploticus is already very good. This is not intended as
criticism. I know you're probably not interested in redoing
the source code. I am not volunteering to do the work. (You
knew that was coming...) There may be things I don't know
that might make my suggestion unworkable (if so, I'd be
interested to know about them).
