View Histogram
The view histogram interface provides you with a view of the
image's current histogram graph depending on where the view histogram is
inserted into the processing pipeline. A histogram is a graphical display of
the number of pixels (the Y or vertical axis) with the pixel value (the X or horizontal
axis 0-255). Using an images histogram you can quickly see the pixel color
distribution and how the various image processing components effect an images
histogram.
It is essentially provides another way of looking at the same image information. The vertical axis
representing the number of pixels at that intensity and the horizontal axis representing the color
intensity of the image's pixels.
Instructions
1. Select which color channel (red, green, blue, intensity) you would like to see displayed in the histogram.
2. Select the chart type - line or bar.
3. Select the amount of histogram smoothing to perform. Smoothing the histogram allows you gain a better
understanding of the histogram's shape by reducing the amount of minor spikes that typically occur in a histogram.
