[Godbert] ImageConverter.cs has System.OutOfMemoryException when export a model with 2k image

[ecyxb]

When I try to export the m0640 model (Boss for e8s) at Godbert, it runs for a long time without ending.
After that I compiled and ran Godbert locally and found that the program threw an OutOfMemoryException at ImageConverter.cs-line 136(fuction GetA8R8G8B8).The reason is to new a byte array of length 2048*2048*4
At the time the exception was thrown, my computer still had fairly free memory. I'm not familiar with the .Net, so I've tried some solutions, including compressing space and GC, allowing the opening of Objects larger than 2G, but none of them work.
