    @brief
    Binning is used to decrease the image size.
 
    @supportedPixelformats{ImageTransformation}
 
    This method reduces resolution by summarizing or averaging groups of pixels
    in the horizontal (x) and/or vertical (y) directions.
    It helps preserve image quality by minimizing aliasing artifacts.
 
    @note Processes the entire image, ignoring any specified image region.
 
    @note The alpha channel of the input image (if present) is also ignored.
              This is because the alpha channel can have different interpretations
              — such as transparency, segmentation labels, or masks —
              each of which would require different handling during binning.
              Consequently, the alpha channel of the output image is always set to the maximum possible pixel value.
 
    @note Binning permanently reduces image resolution. The original resolution cannot be recovered
              after binning is applied.

        - x = 1
