Post any defects you find in the released or beta versions of the ImageMagick software here. Include the ImageMagick version, OS, and any command-line required to reproduce the problem. Got a patch for a bug? Post it here.
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:
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.
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).
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.
