Magick.NET version
13.3.0.0
Environment (Operating system, version and so on)
Windows10, net framework 4.7.2
Description
image.Quality changed from 0 to 1 when i set image.Quality = 0
Can I set this minimum value ?
For example, if quality=0, it defaults to 35 (This minimum value can constrain all image formats, such as jpg, jp2...)
I think it's meaningless to set quality=1 for image.

I want to know , how to get image.Quality when load jpeg2000 image.
i found image.Quality is 0 when load 3.jp2 ( it's inside the zip file ) ,
but when i save it use image.Quality = 100, it filesize is 1.63M (24bit)
when i save it use image.Quality = 30, it filesize is 328k
I want to get the value of image quility when loading the jpeg2000 image,
so I can make sure the file size doesn't change too much when saving the same jpeg2000 image.
Steps to Reproduce
image.Quality = projectimageinfo.OriQuality;
look at the 1.gif file inside the zip file
