Hello list, I've just started attempting to use pyx, and am faced with
an awkward situation when trying to feed it a JPG. A minimalistic example:
import Image
from pyx import *
f="myfile.jpg"
im=Image.open(f)
w,h=im.size
print w,h #gives the correct values for width and height, im.info
has no DPI values in it.
c=canvas.canvas()
i = bitmap.jpegimage(f)
c.insert(bitmap.bitmap(0,0,i,compressmode=None)) #error occurs here
c.writePDFfile("output")
When ran, the following error occurs:
File "/usr/lib/python2.4/site-packages/pyx/bitmap.py", line 179, in
__init__
widthdpi, heightdpi = image.info["dpi"] # XXX fails when no dpi
information available
And sure enough - as noted in the snippet above, the image has no DPI
data. Much the same happens when trying to feed it the *im* image by
the method documented in the examples.
I DO, however, have both width and height for it... if only I could feed
them to pyx somehow. Am I missing a different constructor or some such ?
Or, in a slightly bassackwards manner, is there a way to inject DPI
information into the image with the PIL? Basically any workaround will do.
Thanks for your time. Best regards,
Manuel
