//Also use ogrinfo to see more details** GISNET-1813. Added .NET6 and .NET8 versions of Aspose.GIS with Aspose.Drawing **
// The only one difference is that Aspose.Drawing.Common will be used instead of System.Drawing. This was made to avoid ambiguous code.
// If you want to switch from NetStandard 2.0 or from .NET Framework and you use Types from System.Drawing you can just make mass replace of "System.Drawing" to "Aspose.Drawing" in Visual Studio or other IDE.
// Aspose.PSD Team continues support NetStandard and .NET Framework with System.Drawing.
