Hi all, I hope this is the right place where to ask.
I've started looking in the python api oiio, and so far so good (with a
bit of help from the sources) ,
on retrieving the metadata from the images .
I'm trying now to resize some images and converting them to jpgs
('thumbnails')
All Jpgs images are resized correctly but not the others types (exr,
dpx, etc..).
I've got a look at the resize of oiioutils , but I haven't managed to
replicat it.
Any help is appreciated :)
Cheers.
