Hi, We have Zope 2.3.1 installed, running with Python 1.5.2, and python image library 1.1.1, on a PC with SUSE Linux 7.1. When we run the following code from python we have no prob, we get the rectangle image file img.png, and we also see it in xv according to the im.show() import Image, ImageDraw im = Image.new("RGB",(200,200)) draw = ImageDraw.Draw(im) draw.rectangle((10,10,100,150), fill=(255,255,255)) del draw im.show() im.save("/usr/tmp/img.png","PNG") Now the problem is when we use the same code in a python external method called from zope. we get the following error: Error Type: AttributeError Error Value: _save ... /db1/Zope-2.3.1-linux2-x86/Extensions/feature_view.py, line 114, in draw_segment File /usr/local/lib/python1.5/site-packages/PIL/Image.py, line 674, in save File /usr/local/lib/python1.5/site-packages/PIL/PngImagePlugin.py, line 410, in _save AttributeError: (see above) feature_view.py, line 114 corresponds to the im.save line The funny thing is that a img.png file is saved to disk, but is corrupted, but we still can see the correct image from xv, according to the im.show() call. Any idea on what the prob might be?? Thanks Francisco Andreas
