If for some reason the midpoint of a detector pixel is not representative for the average scattering intensity of the entire pixel it is possible to resort to Monte-Carlo integration.
To request Monte-Carlo integration over detector pixels, use
simulation.options().setMonteCarloIntegration(True, n, seed=0)
where n is the number of scattering intensity evaluations per pixel,
and the optional seed determines the random sample.
Each detector pixel uses a fresh mt19937 generator seeded with seed,
so that results are reproducible and independent of the number of
threads. The GSL environment variables GSL_RNG_TYPE and GSL_RNG_SEED
have no influence.
Example: Monte-Carlo.
