Syntax
VB
Copy
Function Diff ( 
	vOperand2 As Object,
	<OptionalAttribute> vOperand1 As Object
) As McImage

Parameters

vOperand2
Type: SystemObject
Second operand of the operation: McImage, or number (array for color images).
vOperand1 (Optional)
Type: SystemObject
Optional first image operand (operator applies to parent image when parameter is omitted).

Return Value

Type: McImage
The resulting McImage.

Implements

IMcOperationsDiff(Object, Object)
Remarks
For new applications it is recommended that you use DiffEx where the additive offset and mcConversionMode can be passed as arguments. A conversion is performed on vOperand2 so that it has the same type as the source image. The conversion rules are defined by the value of the Conversion property. Offset is added to the result of the operation to produce the final result: Abs( Parent image [or vOperand1] - vOperand2 + Offset ) which is stored in the parent image or vOperand1 if there is no parent. For floating point image types, the stored results may exceed the bounds of the current destination McImage.RangeMin to McImage.RangeMax. These range properties are not changed automatically.
