Storing from PDF to IMG

[Max]

Dear All,

I'm always storing the img I receive in the blobstore using this code:

class UploadHandler(blobstore_handlers.BlobstoreUploadHandler):
 def post(self):
 upload_files = self.get_uploads('File')
 blob_info = upload_files[0]
 fotos = FOTO()
 fotos.link = blob_info.key()
 fotos.Tlink = images.get_serving_url(fotos.link, 94)
 fotos.Glink = images.get_serving_url(fotos.link, 800)
 fotos.put()

Now I receive a PDF and I have to store an IMG.

And I'm thinking to use the conversions tool as per below.

from google.appengine.api import conversion

# Create a conversion request from HTML to PNG.
asset = conversion.Asset("text/html", "<b>some data</b>", "test.html")
conversion_obj = conversion.Conversion(asset, "image/png")

result = conversion.convert(conversion_obj)
if result.assets:
  # Note: in most cases, we will return data all in one asset.
  # Except that we return multiple assets for multiple pages image.
  for asset in result.assets:
    doSomethingWithAsset(asset.data)
else:
  handleError(result.error_code, result.error_text)

My question is:

How can I store the asset? Could I still use the way I was?

Thanks

Max

You must use the Files API to write the generated image to the blobstore.

Where is the file api?

Sorry, I can't understand what you refer to. Could you please push me in the right direction?

Have you figured this out?  I am looking for someone to build me a PDF to Image conversion tool using GAE.  Are you interested?

Hi Mike,
I'm sorry but the conversion Api doesn't work. I'm working on a alternative way, but appengine is facing big problem with the PDF management.

Max: What is the problem with conversion API,it's simple!!

[Max]

Really Simple!

This is my code:

class FAX(db.Expando):
    date = db.DateTimeProperty(auto_now_add=True)


class LogSenderHandler(InboundMailHandler):
    def receive(self, mail_message):
        for elemento in mail_message.attachments:
            asset = conversion.Asset("application/pdf", str(elemento[1]), "Fax.pdf")

            conversion_obj = conversion.Conversion(asset, "image/png")
            result = conversion.convert(conversion_obj)

            for elemento2 in result.assets:
                fax = FAX()
                fax.immagine = elemento2.data
                fax.put()


def main():
    application = webapp.WSGIApplication([LogSenderHandler.mapping()], debug=True)
    wsgiref.handlers.CGIHandler().run(application)


if __name__ == '__main__':
        main()

This is my code. It must work, but it doesn't.
