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.

ice.Image And(b)

Logical AND operation.

Parameters

b: Second operand (ice.Image).

ice.Image Eq(b)

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

Parameters

b: Second operand (ice.Image).

ice.Image Ge(b)

"Greater-than-or-equal" operation.

Parameters

b: Second operand (ice.Image).

ice.Image Gt(b)

"Greater-than" operation.

Parameters

b: Second operand (ice.Image).

ice.Image Le(b)

"Less-than-or-equal" operation.

Parameters

b: Second operand (ice.Image).

ice.Lt(b)

"Less-than" operation.

Parameters

b: Second operand (ice.Image).

ice.Image Nand(b)

"Not-and" operation.

Parameters

b: Second operand (ice.Image).

ice.Image Nor(b)

"Not-or" operation.

Parameters

b: Second operand (ice.Image).

ice.Image Not()

Unary logical complement.

ice.Image Ne(b)

Logical "not-equal" operation.

Parameters

b: Second operand (IceImage).

ice.Image Or(b)

Logical OR operation.

Parameters

b: Second operand (ice.Image).

ice.Image Xnor(b)

Exclusive "not-OR" operation.

Parameters

b: Second operand (ice.Image).

ice.Image Xor(b)

Exclusive OR operation.

Parameters

b: Second operand (ice.Image).
