Flags for the ApplyMathematicalLogicCommand

The following flags indicate the channel that will be used:

Value	Meaning
Master	All channels.
Red	Red channel only.
Green	Green channel only.
Blue	Blue channel only.

The following flags indicate how to treat the color value:

Value	Meaning
ValueDoNothing	No change.
ValueNot	Invert the color, resulting in its complement.
ValueZero	Change all bits to 0.
ValueOne	Change all bits to 1.

The following flags indicate the mathematical operation to use. The operations are performed between each component (R, G and B) and Factor:

Value	Meaning
OperationAnd	Combine each pixel component value and nFactor using a bitwise AND (&).
	(pixel = pixel & Factor)
OperationOr	Combine each pixel component value and nFactor using a bitwise OR (\|).
	(pixel = pixel \| Factor)
OperationXor	Combine each pixel component value and nFactor using a bitwise XOR (^).
	(pixel = pixel ^ Factor)
OperationAdd	Add pixel component value to the nFactor clamping the result to the maximum allowed pixel value.
	(pixel = min(pixel + Factor, MaximumPixelValue) )
OperationSubtractFactor	Subtract each pixel component value from the nFactor, clamping the result to the allowed pixel range.
	(pixel = min(max(Factor - pixel, MinimumPixelValue), MaximumPixelValue) )
OperationSubtractValue	Subtract nFactor 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 Factor 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 nFactor by each pixel values. If the pixel values are 0, the result set to maximum allowed pixel value. (pixel = pixel ? min(Factor / pixel, MaximumPixelValue) : MaximumPixelValue)
OperationAverage	Use the average of the each pixel component value and Factor. (pixel = (pixel+Factor) / 2).
OperationMinimum	Use the lesser of the pixel component values and Factor:
	(pixel = min(pixel, Factor) )
OperationMaximum	Use the greater of the pixel component values and Factor:
	(pixel = max(pixel, Factor) )

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)

The following flags indicate how to treat the output value:

Value	Meaning
ResultDoNothing	No change.
ResultNot	Invert the color, resulting in its complement.
ResultZero	Change all bits to 0.
ResultOne	Change all bits to 1.

If the Flags property is OperationAnd, OperationOr, OperationXor, OperationAdd, OperationMinumum, OperationMultiply, OperationMaximum, OperationDivisionByValue , or OperationSubtractValue, the valid range of Factor is:

From MinimumPixelValue to MaximumPixelValue.

For Flags equal to OperationSubtractFator, OperationDifference, OperationAverage, the valid range of Factor is:

From 2 * MinimumPixelValue to 2 * MaximumPixelValue.
