Did you know that there's a Zope Product called Photo that uses PIL? Download that and look into the source. Peter ----- Original Message ----- From: "Jerome Alet" <alet@unice.fr> To: <zope@zope.org> Sent: Friday, June 01, 2001 11:46 AM Subject: [Zope] PIL+Zope: what's wrong with this code ?

Hi,

I plan to use PIL in an external method to retrieve Images from de ZODB and transform them to PIL Images.

When I use the following code I've got an error which basically says:

"Not enough image data"

This seems to be a PIL error, not a Zope's one, but I really can't understand what the problem is, except that I don't know what mode parameter to pass to fromstring(), I've tried "1", "P", "RGB" etc... but without luck:

--- CUT --- import PIL.Image

# get the logo GIF Image from the ZODB # This object exists and is OK when viewed from the ZMI logo = getattr(self, "logo") imgdata = logo.data if type(imgdata) is not type('') : temp = '' while imgdata is not None : temp = temp + imgdata.data imgdata = imgdata.next imgdata = temp MyPILImage = PIL.Image.fromstring("1", (logo.width, logo.height), imgdata) --- CUT ---

I'm really not sure about the two first parameters that the PIL.Image.fromstring() function need, the first one is the mode, the second is the size.

Could someone with a PIL+Zope experience show me a code snippet to convert Zope Image objects (in any format) to PIL Images ?

Thanks in advance.

PS: I use Zope 2.3.2 and PIL 1.1.1
