Filter Control Parameters

Filter Control Parameter	Type	Default Value	Available Values	Description
BackColor	Int 32	0	Any positive value	This parameter is used to set background color. If BackColor = 0, then the black background color is set, otherwise the white background color is set.
Width	Int 32	512	Any positive value	Defines the DIB width of the loaded image. The DIB height is calculated using the file's scale factors.

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:

www.ecma-international.org/

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