Working with Vector Data

ImageGear for .NET provides native support for vector formats. Examples of such formats include PDF and and CAD/vector file formats such as DXF, DWG, CGM, DGN, HPGL, and U3D. When you load any of these vector formats, the resulting page object is of type ImGearVectorPage, which is derived from ImGearPage Class. The page is not automatically rasterized at load time. Instead, its data is kept in vector form for display and processing.

You can work with a vector page as either a general ImGearPage Class object or a more specific ImGearVectorPage object. ImGearVectorPage provides a Rasterize Method that you can use to create a rasterized copy of the vector page.

An even more specific type of page is ImGearVectPage Class, which is derived from ImGearVectorPage. Pages loaded from CAD/vector file formats are available as ImGearVectPage Class. This object is part of the ImageGear.Vector Namespace. It provides properties and methods for controlling display and manipulation of vector data.

ImageGear vector renderer takes advantage of standard system rendering APIs which may be hardware accelerated. Due to differences in graphics chipsets, settings, drivers, and operating systems, performance and appearance (in particular, lighting effects) may vary. It is recommended that you tune and test your application for the environments on which you will be deploying.
