EXIF Orientation data not loading

[salexander6]

Magick.NET version

14.5.0

Environment (Operating system, version and so on)

Windows 11 Home, version 24H2, OS build 26100.3194

Description

I’m seeing a small percentage of images with EXIF Orientation data that isn’t loading.

When I use exiftool (13.24) to inspect the image I see

> exiftool .\sample.jpg -g -G
[EXIF] Orientation : Rotate 90 CW

When I view the same image in Windows File Explorer I see the Orientation data is being used.

But when I load the image using Magick.net the Orientation data is not accessible.

Steps to Reproduce

using var image = new MagickImage(@"C:\temp\sample.jpg");
var exifProfileFromImage = image.GetExifProfile();
$"EXIF: {exifProfileFromImage}".Dump();
$"Dimensions: {image.Width}x{image.Height}".Dump();

// EXIF: (null)
// Dimensions: 3072x4080

I'll also include the exiftool output for 27 images that reproduce this issue, in case it helps.

I suspect that other tooling is doing something differently than reading the app marker segments. I can see there is exif data in the file but it is not read by the jpeg library that we are using to read the file. I suspect that other tooling just reads through the file until it finds an Exif header.

I finally found what is causing this issue. It will be resolved in the next release.
