ImageGear Filter Control Parameters:

Filter Control Parameter Type Default Value Available Values Description
BACKCOLOR AT_INT32 0 0...255 This parameter is used to set background color for image loading. Red, green, and blue components of background color will be set to this value.
WIDTH AT_INT32 512 Any positive value Defines the width of the empty DIB associated with the image after loading. DIB height is calculated using the file's scale factors. See Working with Vector Images.

Comments:

U3D file format, short for "Universal 3D", is a universal vector standard for storing three-dimensional data of all kinds to facilitate data exchange. The specification for this format is the document ECMA-363: Universal 3D File Format. The latest edition of this specification is available at the ECMA web site:

http://www.ecma-international.org/

The U3D format is natively supported by PDF, and 3D objects in U3D format can be inserted into PDF document files and interactively visualized by PDF viewers.

The ImageGear U3D Vector component supports reading, writing, and rasterizing the U3D vector files. It provides read and write support for the following features of the Universal 3D format: CLOD Progressive Mesh, Normals, Colors (diffuse and specular), Views, Lights, Textures, Transparency, Linesets, and Pointsets.
