[reportlab-users] pdfgen gives me AttributeError: jpeg_fh

[Gregory Piñero]

For now I got this to work by switching the relevant lines to:

    img=img.resize((width/2,height/2),Image.BILINEAR)
    c.drawInlineImage(img, x=width/2,y=0, width=width/2,
        height=height/2)

But I guess the other method still needs to get fixed, no?
