[reportlab-users] Appengine - Reportlab (Get Photo from Model)

[Martinho Arantes]

It would be fantastic.
There are many users like me who are having trouble in integrate reportlab
with google app engine.
I am aware that i read in the foruns.

But i think i´m getting close to the solution. I can print to PDF images
from source folder doing this:

image = canvas.ImageReader(StringIO.StringIO(open('myImage.jpg', 'rb').read

> ()))


This piece of code print to PDF myImage.jpg

What i´d like to print was a random image that a user upload. Of course the
code should be different. I´m trying this one:

image = canvas.ImageReader(StringIO.StringIO(image_data)) # image_data
is a raw string containing a JPEG

c.drawImage(image, 0, 0, 144, 144) # Draw it in the bottom left, 2
inches high and 2 inches wide


There´s where i get the error. I changed utils.py

try:
    self._width,self._height,c=readJPEGInfo(self.fp)
except:
    raise RuntimeError('Imaging Library not available, unable to import
bitmaps only jpegs')
 *to this:*
*
*
self._width,self._height,c=readJPEGInfo(self.fp)
