Sample code is here: https://www.e-iceblue.com/Tutorials/Spi ... rself.html
This error occurs in line: imgImagen.Save("convertToBmp.bmp", System.Drawing.Imaging.ImageFormat.Bmp);
I include the code for your reference. I am using the whole namespace path because I had a conflict with other namespace's properties and method names.
I am using a ASP.NET Web Forms project and Visual Studio 2015 to perform my tests.
