C# Class AForge.Imaging.Filters.HSLFiltering

Color filtering in HSL color space.

The filter operates in HSL color space and filters pixels, which color is inside/outside of the specified HSL range - it keeps pixels with colors inside/outside of the specified range and fills the rest with specified color.

The filter accepts 24 and 32 bpp color images for processing.

Sample usage:

// create filter HSLFiltering filter = new HSLFiltering( ); // set color ranges to keep filter.Hue = new IntRange( 335, 0 ); filter.Saturation = new Range( 0.6f, 1 ); filter.Luminance = new Range( 0.1f, 1 ); // apply the filter filter.ApplyInPlace( image );

Initial image:

Result image:

Sample usage with saturation update only:

// create filter HSLFiltering filter = new HSLFiltering( ); // configure the filter filter.Hue = new IntRange( 340, 20 ); filter.UpdateLuminance = false; filter.UpdateHue = false; // apply the filter filter.ApplyInPlace( image );
