Description
After updating from 7.21.0 to 7.24.1 tiff files are not converted to jpg with the correct colors. All color pages (True Color, YCBCR) that are exported have a pink tone to it.
Steps to Reproduce
using (MagickImageCollection layers = new MagickImageCollection(memStream))
{
foreach (var layer in layers)
{
using (var memoryStream = new MemoryStream())
{
layer.Write(memoryStream, MagickFormat.Jpeg);
}
}
}

Can you test this again with the latest release @mohamedhamza7, and close this issue when the pink colors are gone?
Thanks for providing the file. It turns out that ImageMagick had a check missing when reading this file. I pushed a patch to resolve this and this should be fixed in the next release of Magick.NET.
