Any script or tool so far that does software bin 2:2 from 1:1 source image?

[astrospotter]

Seems an odd question but I wonder if there is a tool yet that can take a 1:1 binned image and sum up the 4 pixels to form an output similar to 2:2 but of course with some more noise than would be had if one had shot 2:2 in the field.     There are so many tools and I just need a lead at this time should there be one that does this.  I believe Maxim has one and I could move things to there but it would be nice if already in pix insight.   Kind of like a re-sample but I am concerned the PI resample may not really be doing direct sum of the 4 pixels in a 1:1 to form an output 2:2  image.

This is for part of a process to bring out better large scale structures which will not have any small scale detail anyway.
Thanks, Mark

I think that IntegerResample does what you want.

It'll be pointless now Mark.
2x2 binning (should) improve signal to noise during data collection because you get more signal (4 pixels worth) versus normal read noise. 

There is no benefit doing this in post processing I would argue.  Harm in fact by losing resolution....

It's an old thread, but Google sent me here...
The app PIPP can do bin2.
I would like to know how with Pixinsight.

Yes it's an old thread (is 8 years a record?) but just as the earlier comments say, IntegerResample can be used to bin the data by a factor of 2, reducing the image size and image resolution.

Or maybe your question is something different?

I did not notice that. I will try and see if it's what I need. Thanks
