Is there no possibility to do all of your program in Python? It seems that would make life a lot easier for you.. Can I advise the Python Imaging Library ([URL="http://www.pythonware.com/products/pil/#pil117"](link here)[/URL] if you dont want to duplicate work. Hope this seems a good… Re: ctypes help 15 Years Ago by vegaseat Your assumption about [B]graydata[/B] is probably correct if you just follow [B]GetImg()[/B] and [B]pImage[/B] in header file [B]loadbmp.h[/B] Are you passing [B]graydata[/B] in as a pointer? Re: ctypes help 15 Years Ago by Tech B I'm not sure what a pointer is, but I'm passing it as it is after: [CODE] i = 0 while i < 307200: #size of image (640*480) graydata[i] = c_ubyte(gl[i]) #gl = list of grayscale values i += 1 [/CODE] I just read something about pointers on google, would something like this work? [CODE] graydata = ctypes.cast(graydata, ctypes.POINTER(ctypes.… Re: ctypes help 15 Years Ago by Tech B I tried [inlinecode]graydata = cast(graydata, POINTER(c_ubyte))[/inlinecode] and [inlinecode]fd.fdlib_detectfaces(byref(graydata), w, h, threshold)[/inlinecode] and still get the same error. Re: ctypes help 15 Years Ago by The_Kernel I don't think you can just dump a python array into the dll's function. Try initializing graydata like this: [code] graydata_type = ctypes.c_ubyte * (w * h) graydata = graydata_type()[/code] Re: ctypes help 15 Years Ago by Tech B I do initialize it. [CODE] graydata = c_ubyte * (640*480) graydata = graydata() [/CODE] I figured that out when I assigned it the values: [CODE] i = 0 while i < 307200: #size of image (640*480) graydata[i] = c_ubyte(gl[i]) #gl = list of grayscale values i += 1 [/CODE] Re: ctypes help 15 Years Ago by The_Kernel without you posting your code it's hard to know that <hint, hint> Re: Porting help... 15 Years Ago by Tech B I got it working. I used pythons ctypes. I used PIL also to convert RGB to grayscale. I think i have a snippet floating around the python forums.
