in reply to Data conversion of FITS images in PDL
The wfits documentation also lists an array-ref variant for the arguments.
What happens if you try that?
$x->wfits('bar.fits', [16]);
Update:
But now I look at the code, that will not work.
Try adding a hash ref as the third argument.
$x->wfits('bar.fits', 16, {});
And maybe file a bug with PDL. https://github.com/PDLPorters/pdl
