ImageMagick.Number value conversion

[RobertPastisss]

Hello, I have a problem when I want to convert an image with exif data.
For the tag "{pixelxdimension}" and "{pixelydimension}", I try to convert the value with different types (Ushort, short ...) but I have a conversion error back. In addition, the type is always {imagemagick.number} despite the conversion (with Tostring () and when I want to keep the value). Is it a bug? Or do I use a bad type for conversion?

I use the last version of Magick.NET (8.5.0)

Thanks !
