Members

Member Description
None No change. Part of the group of flags that define treatment of the source rectangle.
SourceNot Invert the color, resulting in its complement. Part of the group of flags that define treatment of the source rectangle.
Source0 Change all bits to 0. Part of the group of flags that define treatment of the source rectangle.
Source1 Change all bits to 1. Part of the group of flags that define treatment of the source rectangle.
DestinationNot Invert the color, resulting in its complement. Part of the group of flags that define treatment of the destination rectangle.
Destination0 Change all bits to 0. Part of the group of flags that define treatment of the destination rectangle.
Destination1 Change all bits to 1. Part of the group of flags that define treatment of the destination rectangle.
OperationOr Combine each set of bytes using a bitwise OR ( | ). Part of the group of flags that define the operation to use when combining the data.
OperationXor Combine each set of bytes using a bitwise exclusive OR (^). Part of the group of flags that define the operation to use when combining the data.
OperationAdd Add the byte values, allowing a maximum of 255. Part of the group of flags that define the operation to use when combining the data.
OperationSubtractSource Subtract the source from the destination, allowing a minimum of 0. Part of the group of flags that define the operation to use when combining the data.
OperationSubtractDestination Subtract the destination from the source, allowing a minimum of 0. Part of the group of flags that define the operation to use when combining the data.
OperationMultiply Multiply the byte values, allowing a maximum of 255. The result is calculated as follows: result = (source * dest) / 255. Part of the group of flags that define the operation to use when combining the data.
OperationDivideSource Divide the destination by the source. If source > 0, then the result is calculated as follows: result = min( (dest / source) * 255, 255 ). Otherwise, if source = 0, then result = 255. Part of the group of flags that define the operation to use when combining the data.
OperationDivideDestination Divide the source by the destination. If dest > 0, then the result is calculated as follows: result = min( (source / dest) * 255, 255 ). Otherwise, if dest = 0, then result = 255. Part of the group of flags that define the operation to use when combining the data.
OperationAverage Use the average of the two values. Part of the group of flags that define the operation to use when combining the data.
OperationMinimum Use the lesser of the two values. Part of the group of flags that define the operation to use when combining the data.
OperationMaximum Use the greater of the two values. Part of the group of flags that define the operation to use when combining the data.
ResultNot Invert the color, resulting in its complement. Part of the group of flags that define treatment of the resulting image rectangle.
Result0 Change all bits to 0. Part of the group of flags that define treatment of the resulting image rectangle.
Result1 Change all bits to 1. Part of the group of flags that define treatment of the resulting image rectangle.
SourceCopy Copies the source image to the destination image.

Remarks

These flags are divided into four groupings: source (SRC) flags, destination (DST) flags, operation (OP) flags, and resulting image (RES) flags. The flags apply only to the defined rectangles (not necessarily the whole image). The flags are applied in the following order:

  1. Operations on the source and destination rectangles are applied. These are implemented at the same time.
  2. Combining operations are performed.
  3. Operations on the resulting rectangle are applied.

You can use a bitwise OR (|) to specify one flag from each group.
