LEADTOOLS provides support for working with vector images. The most extensive support is available in the Vector Imaging Toolkit.

If you use the C++ Class Library for loading, using the standard loading functions, you can modify the view port and view mode using the following functions:
LEADTOOLS lets you set the color scheme to use when loading AutoCAD files (DXF and DWG). These files can be loaded either Black on White or White on Black. To determine the current color scheme being used by LEADTOOLS, call LFileSettings::GetAutoCADFilesColorScheme. To set the color scheme to use, call LFileSettings::SetAutoCADFilesColorScheme.
