[Zope] Zope and Image display
Hi- I have a dtml form that loads a binary image from a python script. This works fine with no problems, but I want to return the image and also some other data as well. The only thing is when I return the information in the form of a list, my image won't load. I think that the list automatically changes the binary image into a string or something. Does anybody know about this or some work around by any chance? Here is my python script py_get_image(): *#calling an external method to get binary image ganttImageData = context.loadGanttWSping() #returing a list starting with the image, and then a string return (ganttImageData[0], ganttImageData[1])* Here is the dtml code that works if I don't return it as a list: *dtml-var standard_html_header img src=py_get_image dtml-var standard_html_footer * Here is the dtml code that doesn't work: *dtml-var standard_html_header dtml-in py_get_image dtml-if sequence-start img src=_['sequence-item'] dtml-else dtml-var sequence-item /dtml-if /dtml-in dtml-var standard_html_footer* Also, this doesn't work either: *dtml-var standard_html_header dtml-var py_get_image[0] dtml-var standard_html_footer * Any help would be much appreciated! ___ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )

The webbish way of doing things is to link to an external resource, which is what the 'src' in an 'img' tag is all about. You may return an image from a Python script, but since you have to tell your web browser Hey, that there resource is an image, go fetch it it cannot work to return anything but the binary data. --jcc -- Building Websites with Plone http://plonebook.packtpub.com/ Enfold Systems, LLC http://www.enfoldsystems.com ___ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )
