so i managed to create the dynamic lib for gl2ps < http://www.geuz.org/gl2ps/
> on mac os x 10.4. I can import it using ctypes.
>>> gl2ps = ctypes.CDLL('libgl2ps.dylib')
>>> gl2ps
<CDLL 'libgl2ps.dylib', handle 10b660 at 7a330>
I then ran the header (gl2ps.h) through wraptypes to generate the
python code. I got bunch of errors < http://paste2.org/p/88416 > but I
can import this gl2ps.py file.
>>> import gl2ps
>>> gl2ps
<module 'gl2ps' from '/Library/Frameworks/Python.framework/Versions/
2.5/lib/python2.5/site-packages/gl2ps.pyc'>
>>> gl2ps.gl2psSetOptions()
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: this function takes at least 1 argument (0 given)
I am assuming this is working so far.
But i figured i could not for example access
gl2ps.gl2psBeginPage("test", "gl2psTestSimple",
gl2ps.GL2PS_USE_CURRENT_VIEWPORT , gl2ps.GL2PS_EPS,
gl2ps.GL2PS_SIMPLE_SORT,gl2ps.GL2PS_DRAW_BACKGROUND |
gl2ps.GL2PS_USE_CURRENT_VIEWPORT, GL_RGBA, 0, NULL, 0, 0, 0, buffsize,
FILE, "out.eps")
I get this error
AttributeError: 'module' object has no attribute 'gl2psBeginPage'
I next checked gl2ps.py and found that i had no code generated for
this function gl2psBeginPage
this is what this function in C looks like
GLint gl2psBeginPage( const char *title, const char *producer,
GLint viewport[4],
GLint format, GLint sort, GLint options,
GLint colormode, GLint colorsize,
GL2PSrgba *colortable,
GLint nr, GLint ng, GLint nb,
GLint buffersize, FILE *stream,
const char *filename )
There are two datatypes there "FILE *stream" and "GL2PSrgba
*colortable" that i think caused the problem since ctypes does not
understand those datatypes. (i am not entirely sure if this is the
problem)
I was wondering what would be the appropriate argtype for "FILE
*stream" and "GL2PSrgba *colortable"
I started manually entering argtypes in the generated py file- but am
clueless what to enter for these two datatypes
gl2psBeginPage = _lib.gl2psBeginPage
gl2psBeginPage.restype = GLint
gl2psBeginPage.argtypes = [c_char_p, c_char_p, GLint * 4, GLint,
GLint, GLint, GLint, GLint, ?????, GLint, GLint GLint, GLint, ????,
c_char_p]
Thanks!
