Members

Value	Member	Description
0x00000000	None	No change. Part of the group of flags that define treatment of the source rectangle.
0x00000001	SourceNot	Invert the color, resulting in its complement. Part of the group of flags that define treatment of the source rectangle.
0x00000002	Source0	Change all bits to 0. Part of the group of flags that define treatment of the source rectangle.
0x00000003	Source1	Change all bits to 1. Part of the group of flags that define treatment of the source rectangle.
0x00000010	DestinationNot	Invert the color, resulting in its complement. Part of the group of flags that define treatment of the destination rectangle.
0x00000020	Destination0	Change all bits to 0. Part of the group of flags that define treatment of the destination rectangle.
0x00000030	Destination1	Change all bits to 1. Part of the group of flags that define treatment of the destination rectangle.
0x00000100	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.
0x00000120	SourceCopy	Copies the source image to the destination image.
0x00000200	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.
0x00000300	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.
0x00000400	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.
0x00000500	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.
0x00000600	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.
0x00000700	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.
0x00000800	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.
0x00000900	OperationAverage	Use the average of the two values. Part of the group of flags that define the operation to use when combining the data.
0x00000A00	OperationMinimum	Use the lesser of the two values. Part of the group of flags that define the operation to use when combining the data.
0x00000B00	OperationMaximum	Use the greater of the two values. Part of the group of flags that define the operation to use when combining the data.
0x00001000	ResultNot	Invert the color, resulting in its complement. Part of the group of flags that define treatment of the resulting image rectangle.
0x00002000	Result0	Change all bits to 0. Part of the group of flags that define treatment of the resulting image rectangle.
0x00003000	Result1	Change all bits to 1. Part of the group of flags that define treatment of the resulting image rectangle.

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:

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

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

Group	Flags
Flags that define treatment of the source rectangle	None, SourceNot, Source0, Source1
Flags that define treatment of the destination rectangle	DestinationNot, Destination0, Destination1
Flags that define the operation to use when combining the data	OperationOr, OperationXor, OperationAdd, OperationSubtractSource, OperationSubtractDestination, OperationMultiply, OperationDivideSource, OperationDivideDestination, OperationAverage, OperationMinimum, OperationMaximum
Flags that define treatment of the resulting image rectangle	ResultNot, Result0, Result1, SourceCopy
