Note: | Arithmetic calculations in this table assume 24-bit image data. |
The following are the flags that define treatment of the source rectangle:
Value | Meaning |
No change. | |
Invert the color, resulting in its complement. | |
Change all bits to 0. | |
Change all bits to 1. |
The following are the flags that define treatment of the destination rectangle:
Value | Meaning |
No change. | |
Invert the color, resulting in its complement. | |
Change all bits to 0. | |
Change all bits to 1. |
The following are the flags that define the operation to use when combining the data:
Value | Meaning |
Combine each set of bytes using a bitwise AND (&). | |
Combine each set of bytes using a bitwise OR ( | ). | |
Combine each set of bytes using a bitwise exclusive OR (^). | |
Add the byte values, allowing a maximum of 255. | |
Subtract the source from the destination, allowing a minimum of 0. | |
Subtract the destination from the source, allowing a minimum of 0. | |
Multiply the byte values, allowing a maximum of 255. The result is calculated as follows: result = (source * dest) / 255. | |
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. | |
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. | |
Use the average of the two values. | |
Use the lesser of the two values. | |
Use the greater of the two values. |
The following are the flags that define treatment of the resulting image rectangle:
Value | Meaning |
No change. | |
Invert the color, resulting in its complement. | |
Change all bits to 0. | |
Change all bits to 1. |
