Remarks

This function will re-distribute the pixel values across the given range so that there will be (approximately) equal numbers of pixels with each pixel value (0 to 255).  Input pixels with values above or below the threshold values are not modified in the output.

Can be used to extend the dynamic range of an image.

When applied to multi-channel (RGB, RGBA) images, each channel is modified independently of the others; because of this, colors may shift.  See BrightnessHistogramEqualizeCommand for a similar command that doesn't cause this color shift.

This command processes the image In-Place.
