Hi,

thanks for your version 6.8.2-5. The FITS writing problem of 6.8.2.3 is now fixed, but reading FITS images is still not working properly, especially for 16 bit signed integer FITS format:

You can download all these images under this link (please left click): https://www.dropbox.com/sh/gee1h138nz6olen/uOlN4Gr0pu

Here's the original16bit.tif these images were created from (using PixInsight). Other software like Fitswork, IrfanView (with plugin) or ImageVIEWca loads all of these images properly.

Kind regards
Stefan

Hi,

I wondered why my posting did not appear under the topic, until I found the topic is somehow splitted into two parts? My last reply is not visible under the original topic (until I found a tiny "Next" button).

Kind regards,
Stefan

This bulletin board system uses multiple pages rather than one long page. Also at times the moderators will move or split a topic if it gets off topic and onto some thing other than the original topic.

We can reproduce the problem you posted and have a patch in ImageMagick 6.8.2-5 Beta available by sometime tomorrow. Thanks for the reference images, they were quite helpful.
