ImageGear Filter Control Parameters:

Filter Control Parameter	Type	Default Value	Available Values	Description
IMAGE_FORMAT	AT_INT32	IG_FORMAT_PNG	IG_FORMAT_BMP IG_FORMAT_CAL IG_FORMAT_GIF IG_FORMAT_G4 IG_FORMAT_JPG IG_FORMAT_PCX IG_FORMAT_PCT IG_FORMAT_PNG IG_FORMAT_TGA IG_FORMAT_TIF	Defines the internal format that will be used for saving of raster data inside the DWF file. This only affects saving of raster images to DWF. Allowed values correspond to enumIGSaveFormats constants.
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:

DWF is an open file format developed by AutoDesk for storing DWG files on the Internet. DWF contains a vector based description of drawings and illustrations. The format supports 2D and 3D drawings. Unlike DWG and DXF, DWF is focused on viewing only. It is intended to be used for publishing 2D and 3D CAD drawings so they can be easily viewed without requiring the use of CAD software.

The format may also contain an encapsulated raster image, in one of the following formats: BMP, CAL, GIF, CCITT Group4, JPEG, PCX, PCT, PNG, TGA, TIFF.
