Detailed Description

Algorithm filling an image with uniform random sampled values.

This algorithm allows to fill an image with random sampled values using a uniform law based on a linear congruential random number generator on interval optionally specified (by default, this interval equals to the whole range allowed by the output image buffer type)

On output image value are given by :

Example of Python code :

Example imports

import PyIPSDK
import PyIPSDK.IPSDKIPLUtility as util

Code Example

    # create an image geometry
    geometry = PyIPSDK.geometry2d(PyIPSDK.eImageBufferType.eIBT_UInt8, 510, 509)
    
    # create a uniform random image with a given range
    img1 = PyIPSDK.createImage(geometry)
    util.randomImg(PyIPSDK.createRange(50,  70),  img1)
    
    # create a uniform random image with full image range
    img2 = PyIPSDK.createImage(geometry)
    util.randomImg(img2)

        pRange->setValue<Range::Min>(fMin);
        pRange->setValue<Range::Max>(fMax);
        
        // initialize image content with random values in specified range
        randomImg(pRange, pInImg);
