I have to render a CGM file, so unfortunately I don't get to use the .net namespace. I have to call the DLL interface directly (I'm planning to use L_LoadBitmap and L_PantDC). I'm having some problems getting the definitions of the BITMAPHEADER and FILEINFO structs correct. Has anyone called the DLL api directly via interop? If so, would you be willing to share some sample cource code? Thanks!

It might be easier to use the Main OCX or Raster COM objects in this case because you can move a bitmap between these objects and the .NET components using Leadtools.Compatibility (e.g. RasterImageConverter.ToLeadBitmap).

Is this option feasible for you?

Thanks,

Thank you for your support of LEAD and LEADTOOLS.
Attached is a .NET project that calls the LEADTOOLS V14 DLL's directly to load and paint an image. The information in the LEADTOOLS.CS class can be found in the LEADTOOLS header files. If you have any specific questions, please post back to the forum.

_______________________________
Note by moderator:
In the newer versions of LEADTOOLS such as v19, our .NET assemblies contain the ability to render vector files directly without having to call the C DLLs.
