Your image contains a corrupt tiff tag that causes a MagickCoderErrorException. We made a change to ImageMagick that will allow you to ignore a specific tiff tag. Below is an example that will prevent the MagickCoderErrorException:
using (MagickImage image = new MagickImage())
{
image.SetDefine(MagickFormat.Tiff, "ignore-tags", "33426");
// Or if you want to ignore multiple tags:
image.SetDefine(MagickFormat.Tiff, "ignore-tags", "33426,33428");
MagickReadSettings settings = new MagickReadSettings();
// settings.ColorSpace = ColorSpace.RGB;
settings.Density = new MagickGeometry(300, 300);
image.Read(fileName, settings);
}
