Enum HwmfBinaryRasterOp

    java.lang.Object
      java.lang.Enum<HwmfBinaryRasterOp>
          org.apache.poi.hwmf.record.HwmfBinaryRasterOp

All Implemented Interfaces:
  java.io.Serializable, java.lang.Comparable<HwmfBinaryRasterOp>

    public enum HwmfBinaryRasterOp

extends java.lang.Enum<HwmfBinaryRasterOp>

The BinaryRasterOperation Enumeration section lists the binary raster-operation codes. Rasteroperation codes define how metafile processing combines the bits from the selected pen with the bits in the destination bitmap. Each raster-operation code represents a Boolean operation in which the values of the pixels in the selected pen and the destination bitmap are combined. Following are the two operands used in these operations.

Operand | Meaning
--- | ---
P | Selected pen
D | Destination bitmap

Following are the Boolean operators used in these operations.

Operand | Meaning
--- | ---
a | Bitwise AND
n | Bitwise NOT (inverse)
o | Bitwise OR
x | Bitwise exclusive OR (XOR)

All Boolean operations are presented in reverse Polish notation. For example, the following operation replaces the values of the pixels in the destination bitmap with a combination of the pixel values of the pen and the selected brush: DPo. Each raster-operation code is a 32-bit integer whose high-order word is a Boolean operation index and whose low-order word is the operation code. The 16-bit operation index is a zero-extended, 8-bit value that represents all possible outcomes resulting from the Boolean operation on two parameters (in this case, the pen and destination values). For example, the operation indexes for the DPo and DPan operations are shown in the following list.

P | D | DPo | DPan
--- | --- | --- | ---
0 | 0 | 0 | 1
0 | 1 | 1 | 1
1 | 0 | 1 | 1
1 | 1 | 1 | 0

Method Detail

### values

    public static HwmfBinaryRasterOp[] values()

  Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

      for (HwmfBinaryRasterOp c : HwmfBinaryRasterOp.values())
          System.out.println(c);
