Logical

Each of these functions returns images containing only 1's and 0's, respectively representing Boolean true and false values. They are useful for generating masks. They are the means of performing conditional operations on a per-pixel basis.

And(b)

b: Second operand (IceImage)

Logical AND operation.

Eq(b)

b: Second operand (IceImage)

Logical equality: each pixel is one or zero depending on whether corresponding pixels in operand images are equal or not.

Ge(b)

b: Second operand (IceImage)

"Greater-than-or-equal" operation.

Gt(b)

b: Second operand (IceImage)

"Greater-than" operation.

Le(b)

b: Second operand (IceImage)

"Less-than-or-equal" operation.

Lt(b)

b: Second operand (IceImage)

"Less-than" operation.

Nand(b)

b: Second operand (IceImage)

"Not-and" operation.

Nor(b)

b: Second operand (IceImage)

"Not-or" operation.

Not()

Unary logical complement.

NotEqual(b)

b: Second operand (IceImage)

Logical "not-equal" operation.

Or(b)

b: Second operand (IceImage)

Logical OR operation.

XNor(b)

b: Second operand (IceImage)

Exclusive "not-OR" operation.

Xor(b)

b: Second operand (IceImage)

Exclusive OR operation.
