Detailed Description

addition of an input image and a scalar

Addition of an input image InImg and a scalar InArithmeticVal. On output image values are given by:

Input and output images must have same size.

The scalar value is cast into the greatest type between the input and the output image. If both images have integer values whereas the salar has a real value, precision will be lost.

Code Example

    # opening input image
    inImg = PyIPSDK.loadTiffImageFile(inputImgPath)
    
    # addition of image and scalar
    outImg = arithm.addScalarImg(inImg, 1.0)

Code Example

        // Sample with a generated output image
        // ------------------------------------

        // compute multiplication for input images
        ImagePtr pAutoOutImg = addScalarImg(pInImg, fInArithmeticVal);

        // 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
        addScalarImg(pInImg, fInArithmeticVal, pOutImg);
