Defines the internal format that will be used for saving raster data inside the DWF file. This only affects saving of raster images to DWF. Allowed values correspond to enumIGSaveFormats constants. |
| WIDTH | INT | 512 | Any positive value | Defines the DIB width of the loaded image. The DIB height is calculated using the file's scale factors. |
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 also may contain an encapsulated raster image, in one of the following formats: BMP, CAL, GIF, CCITT Group4, JPEG, PCX, PCT, PNG, TGA, TIFF.
