None
Filter Control Parameter | Type | Default Value | Available Values | Description |
---|---|---|---|---|
BACKCOLOR | AT_INT32 | 0 | Any positive value | This parameter sets view background color for image reading. If 0, black background color is set, otherwise white background color is set. |
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. |
HPGL ("Hewlett Packard Graphics Language") is a vector graphics language used to output vector/CAD drawings to plotters. Due to widespread support among CAD software, it is sometimes used as a vector/CAD interchange format.
