[visionegg] Re: gaussian mask on image

Dear Kenji,

I think you may have found a bug in the 0.9.9 distribution. I believe I fixed this in CVS, and I just made a "bleeding edge" snapshot of the code in preparation for the 1.0 release. I have uploaded it to the sourceforge file site: https://sourceforge.net/project/showfiles.php?group_id=40846

Install this ("python setup.py install" from the command line in the unpacked directory) and, with any luck, your problem should be solved.

Cheers!
Andrew

Dear Andrew:

Thank you for the demo code. I tried it, but it seems the program doesn't work well.
The error occurred again as noted first, such like

----
Traceback (most recent call last):

File "/System/Library/Frameworks/Python.framework/Versions/2.3/lib/ python2.3/site-packages/VisionEgg/Core.py", line 1213, in draw

TypeError: draw_masked_quad() takes exactly 10 arguments (9 given)
----

Is this a problem of installed module versions or path settings ?
I recently installed the VisionEgg and other modules to Win2000 and Mac OS X 10.3.4 following the step-by-step instructions on the web, but the same error occurred in both environments.
Demo programs downloaded from the web work well, including GABOR.PY in which sine gratings are masked by a gaussian window.

Although adding an argument (such as "8" or "32") to draw_masked_quad
could eliminate the error, the image texture didn't appear.

Installed versions are as follows:
        Win2000    OS X
Python    2.2.1    2.3
Numpy    21.0
PIL        1.1.4    1.1.4
PyOpenGL    2.0.0.44    2.0.1.7
Pygame    1.5.3    1.6
(Textures.py    1.84    1.90)

Sincerely,

Kenji Yokoi
