Unit # get and set (CodecsRasterizeDocumentLoadOptions)
A CodecsRasterizeDocumentUnit enumeration member that specify the unit to use for PageWidth, PageHeight, LeftMargin, TopMargin, RightMargin and BottomMargin values.
Possible values are:
Value | Description |
---|---|
CodecsRasterizeDocumentUnit.Pixel | The page width, height or margins are in pixels |
CodecsRasterizeDocumentUnit.Inch | The page width, height or margins are in inches. Default value. |
CodecsRasterizeDocumentUnit.Millimeter | The page width, height or margins are in millimeters |
When using a pixel unit (CodecsRasterizeDocumentUnit.Pixel), the page width and height are multiplied by the current resolution(XResolution and YResolution) to determine the final physical page size).
