Multiply
- All Implemented Interfaces:
- Serializable, Operation
public class Multiply
- extends OperationJAI
Create a new coverage as the multiplication of two source coverages by doing pixel by pixel
multiplication:
result[0][0] = source0[0][0] * source1[0][0]
...
...
result[i][j] = source0[i][j] * source1[i][j]
...
...
result[n-1][m-1] = source0[n-1][m-1] * source1[n-1][m-1]
Make sure coverages have same envelope and same resolution before using this operation.

Multiply
public Multiply()
- Constructs a default
"MultiplyConst"
operation.
deriveRange
protected NumberRange deriveRange(NumberRange[] ranges,
OperationJAI.Parameters parameters)
- Returns the expected range of values for the resulting image.
- Overrides:
deriveRange
in class OperationJAI
- Parameters:
ranges
- The range of values from every sources. For unary operations like
"GradientMagnitude"
, this array has a length of 1. For binary operations
like "add"
and "multiply"
, this array has a length of 2.parameters
- Parameters, rendering hints and coordinate reference system to use.
- Returns:
- The range of values to use in the destination image, or
null
if unknow.
