ImageStatisticsHSL() public method

Initializes a new instance of the ImageStatisticsHSL class.

The mask array must be of the same size as the specified source image, where 0 values correspond to areas which should be excluded from processing. So statistics is calculated only for pixels, which have none zero corresponding value in the mask.

Source pixel format is not supported. Mask must have the same size as the source image to get statistics for.
public ImageStatisticsHSL ( Bitmap image, byte mask ) : System
image System.Drawing.Bitmap Image to gather statistics about.
mask byte Mask array which specifies areas to collect statistics for.
