Direzione di ricerca

Start by comparing how MagickImage and MagickImageCollection read FITS data, focusing on the collection stream and file read paths named in the stack traces. Reproduce with the attached sample FITS image and check the collection constructor tests for existing format coverage. Done means the collection constructors load the FITS image successfully without throwing, while existing collection reads still pass.

Descrizione

Magick.NET version

15.0.0

Environment (Operating system, version and so on)

Linux x64, Windows 11 x64

Description

Images in the .fts (Fits) image format cannot be constructed using any of the MagickImageCollection constructor overloads, see exceptions below.

When using any of the MagickImage constructor overloads, the Fits images are correctly instantiated.

Steps to Reproduce

Actual behavior: Attempting to construct a MagickImageCollection instance using an image in the .fts (Fits) format throws an exception.

Expected behavior: Attempting to construct a MagickImageCollection instance using an image in the .fts (Fits) format works correctly, as it does when constructing a MagickImage instance, and does not throw an exception.
