When working with Vector files, you can use the Vector features, available in selected products, or you can use the Raster C DLL. If you use the Main C DLL for loading, using the standard loading functions, you can modify the view port and view mode using the following functions:

L_2DGetViewMode

L_2DSetViewMode

L_2DGetViewport

L_2DSetViewport

This function may be used with the following Vector file formats: DXF, DWG, WMF, EMF, PCT, CGM, DRW, PLT, TIF (with a DXF saved internally) and Intergraph Vector. For more information on these file formats and their availability, refer to LEADTOOLS Vector Formats.
