Hi,
I'd recommend you to use Qt/PySide. Qt is very mature and well
supported, and PySide is gaining track again (which is really good for
us :-)
Besides, for the kind of work you describe, I'd also recommend you to
use a higher level library (on top of PySide). You have two alternatives:
1. Traits and TraitsUI, from Enthought.
2. Guiqwt, from Pierre Raybaut, the same author of Spyder.
Both let you define sliders and controls to manipulate images very
easily and (I've heard) guiqwt is also quite fast.
Regarding MacOS, my advice is that you really need to update to 10.7
(even if painful). According to our (limited) statistics, very few
people is still living in Snow Leopard compared to the other versions.
Cheers,
Carlos

Hi All,
I'm still a newbie to cross platform development. I chose Python for
the obvious reason. Problems galore on Mac OSX (snowleopard), probably
due to python being installed. So I opted for Anaconda distribution as
that seemed to meet my needs, sections off it's own python version,
has Spyder included etc etc. Which GUI development is recommended? I
struggled to get wxpython working with anaconda, lots of questions on
the web and no real solution for OSX that I can find. I then switched
for pyside\QT which seems fine but I have problems loading jpgs,
again, lot's of questions on the web but no easy solution on OSX. , .
. . .
Any help appreciated on this.
I need to:
1) Load very large images - 4000 x 4000 pixel images.
2) Give end user capability of drawing/moving polygons/paths/markups
on the image.
3) Offer widgets such as sliders to apply filters to the image
(brightness, contrast, . . ) or even better to control brightness \
contrast with shift drag on an image (i.e. needs to be very fast).
I've experimented with wxPython and quite responsive.
I've experimented with PIL and also quite fast.
I've experimented with OpenCV also fast.
I've looked at VIPS - not managed to test but should operate at C++ speed.
I'm struggling with Mac, on Windows seems easier to develop but when I
see problems on Mac such as jpgs not loading I worry about cross
platform compatibility. BTW I really don't want to upgrade to OSX
10.7+ as that will break some apps I have which rely on Rosetta and
I'd rather not get involved with additional virtual machines.
Thanks in Advance!
