Hi,
I'm trying to build a report using zope3 + reportlab 1.20 that I want to
contain some images from a container (which in the code below is called
'item').
Has anyone done this? Can they suggest a technique?
Trying the following:
images = []
for docpage in item.values():
f = tempfile.TemporaryFile()
f.write(docpage.data)
width, height = docpage.getImageSize()
images.append( Image(f, width=width, height=height) )
Only gets me as far as an error (when the images list is placed on the
list containing the document structure):
File "/home/Adam/z3/Zope3/src/zope/component/site.py", line 75, in
queryMultiAdapter
default)
File "/home/Adam/z3/Zope3/src/zope/interface/adapter.py", line 475, in
queryMultiAdapter
return factory(*objects)
File "/home/Adam/z3/products/ccard/pdf/card.py", line 58, in __init__
images.append( Image(f, width=width, height=height) )
File
"/usr/lib/python2.4/site-packages/reportlab/platypus/flowables.py", line
318, in __init__
self._setup(width,height,kind,0)
File
"/usr/lib/python2.4/site-packages/reportlab/platypus/flowables.py", line
327, in _setup
if lazy<=0: self._setup_inner()
File
"/usr/lib/python2.4/site-packages/reportlab/platypus/flowables.py", line
334, in _setup_inner
if img: self.imageWidth, self.imageHeight = img.getSize()
File "/usr/lib/python2.4/site-packages/reportlab/lib/utils.py", line
530, in getSize
if (self._width is None or self._height is None):
AttributeError: ImageReader instance has no attribute '_width'
Has anyone done what I want to? How? Any help would be much
appreciated.
Regards,
Adam
