InkRasterOperation Enumeration

Defines values for performing raster operations on drawn ink.

Declaration

[C++]

typedef enum InkRasterOperation {
    IRO_Black = 1,
    IRO_NotMergePen = 2,
    IRO_MaskNotPen = 3,
    IRO_NotCopyPen = 4,
    IRO_MaskPenNot = 5,
    IRO_Not = 6,
    IRO_XOrPen = 7,
    IRO_NotMaskPen = 8,
    IRO_MaskPen = 9,
    IRO_NotXOrPen = 10,
    IRO_NoOperation = 11,
    IRO_MergeNotPen = 12,
    IRO_CopyPen = 13,
    IRO_MergePenNot = 14,
    IRO_MergePen = 15,
    IRO_White = 16
} InkRasterOperation;

[Microsoft® Visual Basic® 6.0]

Members

The following tables list the enumeration values.

Name Description
Black Specifies black pen color.
NotMergePen Specifies the inverse of MergePen.
MaskNotPen Specifies a combination of the colors that are common to the background color and the inverse of the pen.
NotCopyPen Specifies the inverse of CopyPen.
MakePenNot Specifies a combination of the colors that are common to both the pen and the inverse of the display.
Not Specifies the inverse of the display color.
XOrPen Specifies a combination of the colors in the pen and in the display color, but not in both.
NotMaskPen Specifies the inverse of MaskPen.
MaskPen Specifies a combination of the colors that are common to both the pen and the display.
NotXOrPen Specifies an inverse of XOrPen.
NoOperation Specifies no operation; the output remains unchanged.
MergeNotPen Specifies a combination of the display color and the inverse of the pen color.
CopyPen Specifies the pen color.

This is the default value.
MergePenNot Specifies a combination of the pen color and the inverse of the display color.
MergePen Specifies a combination of the pen color and the display color.
White Specifies a white pen color.

Remarks

Use these values to set the value for the RasterOperation drawing attribute. Any object with a DrawingAttributes property can have this value set.

Note: Many printers do not support many of the available raster operations. Because of this, the colors you see on the display may be different from the colors that you would see if they were printed on paper. This is directly related to the printer drivers or printer hardware. You may need 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.
