ImageGear primarily accepts images as System.Drawing.Bitmap objects. Internally, the .NET Core Runtime uses libgdiplus to load images on disk into these objects. While most images will load correctly with the most recent versions of libgdiplus available in distribution repositories, BMP version 4 and newer images will not have all data loaded properly and will cause some images to not be processed correctly.
Microsoft recommends using libgdiplus version 6.0.1 or higher: https://docs.microsoft.com/en-us/dotnet/core/install/linux-scripted-manual#common-dependencies
If this version is not available for your distribution, you can find instructions for adding the Mono repository and getting the most recent version here: https://www.mono-project.com/download/stable/#download-lin
