Значение свойства

Тип: Microsoft.Ink.RasterOperation

Заметки

The RasterOperation enumeration defines values for performing raster operations on drawn ink. For example, if you want to perform subtractive transparency, set the raster value to MaskPen.

For a complete list of available raster operations, see the RasterOperation enumeration type.

Примечание.
Many printers do not support many of the available raster operations. Because of this, the colors displayed may be different than the colors printed. This is directly related to the printer drivers or printer hardware. You may have to experiment to determine which printers can produce the correct output when various raster operations are set on ink.

When the RasterOperation value is set to anything other than CopyPen, all drawing attributes—anti-aliasing, smoothing, transparency, and pressure—are ignored.

Примеры

This C# example sets the raster operation of the InkCollector object's default pen to XOrPen.

theInkCollector.DefaultDrawingAttributes.RasterOperation =
    RasterOperation.XOrPen;

This Microsoft® Visual Basic® .NET example sets the raster operation of the InkCollector object's default pen to XOrPen.
