I find the matrix methods in Pycairo to be an annoying hodge-podge of
ones that overwrite the Matrix object in-place (init_rotate, invert)
versus ones that concatenate additional transformations (rotate, scale,
translate) versus ones that return new matrices without modifying
the originals

OK your error occurs because we need to set up the renderPM canvas with an
initial font (for compatibility with the PDF canvas

the reportlab graphics renderPM(_renderPM) module does most things
with T1 and TTF and works linux/win32. We use freetype2 internally to
extract the curves from ttf and then draw them with libart_lgpl which
does anti-aliasing.
I just tried reportlab and RenderPM. I got the same error
value for some fonts, and there are some
TTF fonts that are rendered incorrectly (UTF-8)

Hi All,
I have a program that works under Ubuntu. It loads a TTF font into
pycairo, using libfreetype. The code snippet I used was taken from here:
http://cairographics.org/freetypepython/
Now I need to use the same program from Microsoft Windows. But Windows
does not have "libfreety
Hi,
I'm trying to create a rectangle when the user presses or releases the
mouse over a cairo object.I'm using the eventBox to capture the mouse
events.
Now the problem is the shapes is beng drawn when I call it from the
expose_event event handler and nothing happens when I call the same

I'm doing some image processing in PIL, and I want to
display the results in a GTK window using PyCairo, so
I create a Cairo image surface from the PIL Image like
this:
mfile = StringIO.StringIO()
final.save(mfile, format="PNG")
ima =
cairo.ImageSurface.
I'd like to experiment with pyCairo, but I'm having installation
problems. I've downloaded cairo 1.4.0, libpng 1.2.8, zlib 1.2.3, and
pycairo 1.4.0, and I've placed the DLLs for cairo, libpng, and zlib in
c:\python25\dlls\. However, when I run "setup.py install"
Solved my own problem :-)
For future reference here is the solution:
class PycairoContext(Structure):
_fields_ = [("PyObject_HEAD", c_byte * object.__basicsize__),
("ctx", c_void_p),
("base", c_void_p)]
z = PycairoContext.from_address(id(ctx))
print z.ctx

Can you access the c object of a python object directly? Can this be
done in ctypes or directly throught python functions without reverting
to forking the python module?
scanario:
I have pyctx object that i get in python like this:
pyctx = cairo.Context(surface)
defined in the python extension t
I'll be out of the office until approximately August 20th. If you have any
