RemarksRules for Arithmetic Image Type
There are four rules governing arithmetic image types. The principle is to provide the smallest type without loss of precision.
Input value casting
In the case of OIV.ImageViz.Engines.ArithmeticAndLogic.ArithmeticOperations.SoArithmeticValueProcessing, the type of the output image is deducted from the type of the input image and the smallest type able to contain the inputValue without loss of precision.
Basical Rule
This rule is used for addition, subtraction and division operations.
Promotion rule
This rule is used for multiplication operation. Please, note that some operators with a single input also use this rule taking the same type for both headers row and column. For instance, OIV.ImageViz.Engines.EdgeDetection.Gradient.SoGradientOperatorProcessing2d and OIV.ImageViz.Engines.EdgeDetection.Gradient.SoGradientOperatorProcessing3d engines follow also this rule.
Rule for minimum operation
Rule for maximum operation
