Hi all! Quick question:

I'm trying to write a program for my N73 that will perform numberplate recognition (mental? perhaps, but it keeps me busy). This is my first foray into Symbian so I thought I would make my life easier by using Python to script the interface, and a C extension to provide the grunt.

I've successfully compiled my basic python and C stuff, but I appear to have hit a major hurdle - I'm passing an image object from the python to C extension, but I have no idea what format it appears in! Is there a special argument I need to call PyArg_ParseTuple() with? Alternatively, has anyone had any success hacking it apart? I'd guess it's in some sort of (x,y,3) array with a header stuck on the front (or the back?!) but I can't make any sense of my data.

Any suggestions? :-)

The Image object represents a native Symbian side object called a CFbsBitmap. You can extract a pointer to the CFbsBitmap from an Image object by calling the method ._bitmapapi(). That will return the CFbsBitmap * wrapped inside a CObject (see Python/C API docs for an explanation on what that is).

Currently if you want to hack on Image object internals efficiently from your C++ code you need to extract that CFbsBitmap and extract data from it using Symbian C++ methods.
