Comments

A 3D file format usually does not have a physical size. The user can specify a viewport (physical size upto which the drawing can be rendered) with L_2DSetViewport . How the drawing is to be rendered inside this viewport depends on the current viewport mode set with L_2DSetViewMode. Default viewport size is 640x480 pixels.

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

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.
