The problems of file with large coordinate and high resolution

I have some problems in converting DWG file to PNG file with aspose.cad 20.1 and 20.3.

If the resolution of output is very high such as 50000*50000, an Aspose.CAD.CadExceptions.ImageSaveException will occur.
So I try to convert one part by part using CadVportTableObject. But the result is not good if the origin dwg file has large coordinate such as largecoordinate.png。If the coordinate is small the result is gooe such as smallcoordinate.png.

Is there a good methord to conver a DWG file with large coordinate to a png file with high resolution?

the project and the files are here: http://frc.tpddns.cn:1108/sharing/WSszv99sk
