5️⃣ Additional context
Translated By Google Translate
I saw a similar closed issue, but it mentioned AVFI and the error message was different. #2035
It can be opened in the old version v9.1.6.14, but the image resolution will only read 16384x7969
If a smaller image (22269 x 8728; 7.11MB) is used, it will also be reduced to 16384x6421
@CPuddingOwO it looks like an issue with Magick.NET, can you help to report there https://github.com/dlemstra/Magick.NET/issues
Probably not. I can't seem to get any log information other than the automatically popped-up ErrorMessage, and most of my words were translated using Google Translate, so there might be something wrong with my expression. Maybe you can report it, because I don't know how to get a more detailed log file.
I haven't learned any .NET development, so I don't know how to do it, sorry.
@CPuddingOwO It will be fixed in the next release.
Has the issue of excessive memory usage when loading such high-resolution images been fixed?
In next version, IG will switch to use WIC (Windows native codec) for the large images (if supported). This will reduce the memory usage and much faster than using Magick library.
Users can set the minimum image dimension to use WIC via setting MinDimensionToUseWIC in igconfig.json. The default value is 10000, meaning that if the width or height of the image is from 10000, IG will try to use WIC.
