My probeleme : In line 23 "img.show()" Don't work, normally I show
the image
but it's not work, but strangely in line 24 "img.save(fp="./
ana.bmp")" it's
work
WHERE IS THE PROBLEME.
I have this error in shell : "(eog:3176): GLib-WARNING **: GError
set over
the top of a previous GError or uninitialized memory.
This indicates a bug in someone's code. You must ensure an error is
NULL
before it's set.
The overwriting error message was: Error in getting image file info "
os: ubuntu 9.10
Hi issolah,
I don't know what your problem is but I have a few suggestions --
1) You say that img.show() doesn't work. How does it fail? Is that
where you get the GLib warning?
2) I'm glad you posted your code, but because it has line numbers,
it's awkward to copy & paste into a local example. Please show your
code without line numbers.
I'm unfamiliar with PIL, so this is just a wild guess, but based on
the GLib error it seems like you haven't initialized something
properly. Sorry I couldn't be more helpful. Maybe someone who knows
more will answer.
Good luck
Philip
