I would like to mask DotArea2D (with a circle mask) as Andrew suggested in color_grating.py but failed.

My questions are: Is it possible to mask any stimulus and DotArea2D in particular?

I didn't suggest to use a mask with DotArea2D -- the VisionEgg.Textures.Mask2D class is only for textured stimuli. So, it does not work with any stimulus.

Any hint?

Yes -- modify your own copy of DotArea2D to draw random dots in a circle.

Hope this helps...

Cheers!
