Description Dont-spam-me 2012-11-24 19:32:01 UTC

Hi, 

I think cairo.Win32Surface(dc) crashes under 64-bit Python v2.7.2 *probably* due to the fact that a DC handle is a long int which Win32Surface could not handle.

This is just my guess, hope someone could verify.

I used a PDFSurface instead and it works perfectly fine.

Here is a sample code to reproduce the crash:

import cairo
from win32api import *
from win32gui import *

dc = CreateCompatibleDC(0) # 0 means compatible with screen
bm = CreateCompatibleBitmap(dc, 100, 100)
old = SelectObject(dc, bm)
s = cairo.Win32Surface(dc) # crashes here

You can verify that 'dc' is non-NULL and is a long int.
