<p>Functions for scaling images to lower bit depth. </p>
<p>To map source pixel srcPixelValue to destination pixel dstPixelValue the following equation is used: </p>
<pre class="fragment"> dstPixelValue = dstMinRangeValue + scaleFactor * (srcPixelValue - srcMinRangeValue)
</pre><p>where scaleFactor = (dstMaxRangeValue - dstMinRangeValue) / (srcMaxRangeValue - srcMinRangeValue).</p>
<p>For conversions between integer data types, the entire integer numeric range of the input data type is mapped onto the entire integer numeric range of the output data type.</p>
<p>For conversions to floating point data types the floating point data range is defined by the user supplied floating point values of nMax and nMin which are used as the dstMaxRangeValue and dstMinRangeValue respectively in the scaleFactor and dstPixelValue calculations and also as the saturation values to which output data is clamped.</p>
<p>When converting from floating-point values to integer values, nMax and nMin are used as the srcMaxRangeValue and srcMinRangeValue respectively in the scaleFactor and dstPixelValue calculations. Output values are saturated and clamped to the full output integer pixel value range.</p>
