true to consider the margins when rendering a sheet or a page; otherwise, false. Default value is false.
When the value of MultiPageEnableMargins
is true, the engine will use the margins set in CodecsRasterizeDocumentLoadOptions.LeftMargin, TopMargin, RightMargin and BottomMargin when rendering a sheet or page. These margins can be set using rasterCodecs.Options.RasterizeDocument.Load.
