Thank-you so much.

Yes - POVs aperture code is pretty substandard.

I just use a pigment or a PNG image of the bokeh, and sample it with an halton
sequence. I then dim the image by the gray value returned (i.e. this sample is
76% bright, that one is 40% bright). If the value is below a threshold (e.g. 5%)
I take another sample.

The code is all in my Camera35mm macros I posted a year or so ago.

Cheers,
Edouard.
