Members
| Member | Description |
|---|---|
| Master | All channels. |
| Red | Red channel only. |
| Green | Green channel only. |
| Blue | Blue channel only. |
| ValueDoNothing | No change. |
| ValueNot | Invert the color, resulting in its complement. |
| ValueZero | Change all bits to 0. |
| ValueOne | Change all bits to 1. |
| OperationAnd | Combine each pixel component value and the Factor property using a bitwise AND (&). (pixel = pixel & Factor) |
| OperationOr | Combine each pixel component value and the Factor property using a bitwise OR (|). (pixel = pixel | Factor) |
| OperationXor | Combine each pixel component value and the Factor property using a bitwise XOR (^). (pixel = pixel ^ Factor) |
| OperationAdd | Add pixel component value to the Factor property, clamping the result to the maximum allowed pixel value. (pixel = min(pixel + Factor, MaximumPixelValue) ) |
| OperationSubtractFactor | Subtract each pixel component value from the Factor property, clamping the result to the allowed pixel range. (pixel = min(max(Factor - pixel, MinimumPixelValue), MaximumPixelValue) ) |
| OperationSubtractValue | Subtract the Factor property from each pixel component value, clamping the result to the allowed pixel range. (pixel = min(max(pixel - Factor), MinimumPixelValue, MaximumPixelValue) ) |
| OperationAbsoluteDifference | Calculate the Absolute difference between the Factor property and each pixel component value. (pixel = abs(pixel - Factor)) |
| OperationMultiply | Multiply each pixel component value by Factor/100. (pixel = pixel * Factor / 100) |
| OperationDivisionByFactor | Divide each pixel component value by Factor/100. An error will be returned if Factor = 0. (pixel = pixel * 100 / Factor) |
| OperationDivisionByValue | Divide the Factor property by each pixel value. If the pixel value is 0, the result is set to the maximum allowed pixel value. (pixel = pixel ? min(Factor / pixel, MaximumPixelValue) : MaximumPixelValue) |
| OperationAverage | Use the average of the each pixel component value and the Factor property. (pixel = (pixel+Factor) / 2). |
| OperationMinimum | Use the lesser of the pixel component values and the Factor property. (pixel = min(pixel, Factor) ) |
| OperationMaximum | Use the greater of the pixel component values and the Factor property. (pixel = max(pixel, Factor) ) |
| ResultDoNothing | No change. |
| ResultNot | Invert the color, resulting in its complement. |
| ResultZero | Change all bits to 0. |
| ResultOne | Change all bits to 1. |
Remarks
These flags have a FlagsAttribute attribute that allows a bitwise combination of its member values.
You can use a bitwise OR (|) to specify one flag from each group.
| Group | Flags |
| Flags that indicate the channel that will be used | Master, Red, Green, Blue |
| Flags that indicate how to treat the color value | ValueDoNothing, ValueNot, ValueZero, ValueOne |
| Flags that indicate the mathematical operation to use | OperationAnd, ValueNot, ValueZero, ValueOne, OperationAnd, OperationOr, OperationXor, OperationAdd, OperationSubtractFactor, OperationSubtractValue, OperationAbsoluteDifference, OperationMultiply, OperationDivisionByFactor, OperationDivisionByValue, OperationAverage, OperationMinimum, OperationMaximum |
| Flags that indicate how to treat the output value | ResultDoNothing, ResultNot, ResultZero, ResultOne |
The way MinimumPixelValue and MaximumPixelValue are calculated depends on the bits per pixel and whether the image is signed or unsigned: if the image is unsigned (most common): MaximumPixelValue will be : 255 (8-bit), 4095 (12-bit) or 65535 (16-bit) MinimumPixelValue = 0
if the image is signed (rare case): MaximumPixelValue will be : 127 (8-bit), 2047 (12-bit) or 32767 (16-bit) MinimumPixelValue will be -128 (8-bit), -2048 (12-bit) or -32768 (16-bit)
If the Flags property is set to OperationAnd, OperationOr, OperationXor, OperationAdd, OperationMulitply, OperationMaximum, OperationMinimum, OperationDivisionByValue, or OperationSubtractValue, the valid range of the Factor property is from MinimumPixelValue to MaximumPixelValue. If the Flags property is set to OperationSubtract, OperationDifference, or OperationAverage, the valid range of the Factor property is from 2 * MinimumPixelValue to 2 * MaximumPixelValue.
