--- Comment #2 from caulier.gil...@gmail.com --- I played with FITS on my Macbook pro using Chandra radio telescope samples : https://i.imgur.com/yCFUpFh.png https://i.imgur.com/Bn4kEWj.png https://i.imgur.com/3gZXuVi.png Image come from : https://www.chandra.harvard.edu/photo/openFITS/multiwavelength_data.html Image magick version used to compile under MacOS is 6.9.11, but under Windows version 7.X must not be a problem. I suspect a specificity with your FITS images not very well supported by Image Magick which render an alpha layer image. FITS is a very complex container with plenty of features. We need samples from your collection to investigate. Gilles Caulier -- You are receiving this mail because: You are watching all bug changes.
