image = multiplyAddScalarImg (inImg,inFactor,inOffset)

Detailed Description

affine operation on grey levels of an image

On output image values are given by:

$OutImg[i] = InFactor * InImg[i] + InOffset$

with $ InFactor $ and $ InOffset $ parameters of the operations specified by the user.

The result of the operation automatically saturates if it is out of output image data type range.

Input and output images must have same size.

Example of Python code :

Example imports

import PyIPSDK

import PyIPSDK.IPSDKIPLArithmetic as arithm

Code Example

    # opening input image
    geometry = PyIPSDK.geometry2d(PyIPSDK.eImageBufferType.eIBT_Real32, 510, 509)
    inImg = PyIPSDK.loadTiffImageFile(inputImgPath)
    
    # affine operation on the input image
    outImg = arithm.multiplyAddScalarImg(inImg, 1.5, 10.0)

Code Example

        // Sample with a generated output image
        // ------------------------------------
        // compute multiplication for input images
        ImagePtr pAutoOutImg = multiplyAddScalarImg(pInImg, factor, offset);
        // Sample with a provided output image
        // -----------------------------------
        // create output image
        ImageGeometryPtr pOutputImageGeometry = geometry2d(outType, sizeX, sizeY);
        boost::shared_ptr<MemoryImage> pOutImg(boost::make_shared<MemoryImage>());
        pOutImg->init(*pOutputImageGeometry);
        // compute multiplication of input images
        multiplyAddScalarImg(pInImg, factor, offset, pOutImg);
