How to improve the speed of opening image

[jueqing1015]

Sometimes it takes a long time to open an image. I use the same image

FileStream pFileStream = new FileStream(Url, FileMode.Open , FileAccess.Read );

It's much faster than that MAGICK.NET It's much faster. Is there any way to improve its opening speed?

The reason that FileStream is much faster is because it doesn't need to decode the image.
