You must be using "SpreadsheetGear for .NET Standard" since, to date, this is the only product on NuGet that is offered by SpreadsheetGear.
SpreadsheetGear for .NET Standard does not offer an equivalent to SpreadsheetGear for .NET's
SpreadsheetGear.Drawing.Imageclass due to the fact that .NET Standard 1.3 (and the newly-released 2.0) lacks System.Drawing libraries, whichSpreadsheetGear.Drawing.Imagedepends on; and there are no alternative graphics libraries in .NET Standard (or built on .NET Standard) that could serve as a suitable substitute for which we could build a similarImageclass on top of.Note: I do work for SpreadsheetGear and we are interested in your thoughts on possible alternatives in this area of our .NET Standard product for future releases.
