The ImageGear.Vector namespace provides native support for vector data as used by CAD/vector formats such as DWF, DWG, CGM, DGN, and HPGL. When you load any of these formats, the resulting ImGearPage object is not automatically rasterized at load time. The data is kept in vector form for display and processing. It's possible to display the vector data from different viewpoints and edit individual vector entities. The vector data can also be rasterized, converting it to a bitmap form.
The ImageGear.Vector namespace belongs to the ImageGear21.Formats.Vector.dll assembly.
