Some time ago, there was a thread in this newsgroup on 'drizzle'-like
image resampling methods, much of which is preserved on David's web
page. Well, actually it was mostly a thread on clever and
convoluted histogram tricks, and resulted in some speedy solutions to
array decimation. But the ultimate consensus then was that there is
no good drizzle-like flux conserving image resampler in IDL, and maybe
C is a better way to go.
Before I sit down and reinvent the wheel on this one, I thought I'd
ask around and see what, if any, code for this might exist now a few
years later. I'm looking for a good way to take pixellated data
measured in a camera with known field distortion and resample them
onto a regular grid. Drizzle or PyDrizzle would do what I want,
except it seems fairly nontrivial to get them to accept non-HST data.
(Am I wrong? If anyone has tips on how to do this, I'm all ears.)
If anyone knows of an IDL solution for this, or a C DLM, I'd be most
appreciative... And failing that, at least knowing definitively that
no such thing exists now would probably help fortify my spirits for
writing my own!
Thanks,
- Marshall
