Summary

Performs binary operation, including and, or and xor, on two mask Workspaces, i.e., SpecialWorkspace2D.

Properties

Name	Direction	Type	Default	Description
InputWorkspace1	Input	MaskWorkspace	Mandatory	MaskWorkspace 1 for binary operation
InputWorkspace2	Input	MaskWorkspace		Optional MaskWorkspace 2 for binary operation
OperationType	Input	string	AND	Operator for Workspace1 and Workspace2. Allowed values: [‘AND’, ‘OR’, ‘XOR’, ‘NOT’]
OutputWorkspace	Output	MaskWorkspace	Mandatory	Output MaskWorkspace as result of binary operation

Description

A binary operation will be conducted on two SpecialWorkspace2D (i.e., masking workspace). The binary operations supported include AND, OR and XOR (exclusive or). The operation is done between the corresponding spectra of these two input workspaces, i.e.,

\[spec_i^{output} = spec_i^{in 1} \times spec_i^{in 2}\]

\[spec_i^{output} = spec_i^{in 1} + spec_i^{in 2}\]

\[spec_i^{output} = spec_i^{in 1} \oplus spec_i^{in 2}\]

Output

A SpecialWorkspace2D with the same dimension and geometry as the input two SpecialWorkspace2D.

Usage

Example - Binary Operation Usage

# Create some masked workspaces
ws1 = CreateSampleWorkspace(NumBanks=1,BankPixelWidth=1)
ws2 = CreateSampleWorkspace(NumBanks=1,BankPixelWidth=1)
MaskDetectors(ws1, WorkspaceIndexList=0)
MaskDetectors(ws2, WorkspaceIndexList=0)
a, list = ExtractMask(ws1)
b, list = ExtractMask(ws2)

# Run using AND
_and = BinaryOperateMasks(a, b, OperationType='AND')
# Run using OR
_or = BinaryOperateMasks(a, b, OperationType='OR')
# Run using XOR
_xor = BinaryOperateMasks(a, b, OperationType='XOR')

print(_and.readY(0))
print(_or.readY(0))
print(_xor.readY(0))

Output:

[ 2.]
[ 1.]
[ 0.]
