The filter performs linear correction of RGB channels by mapping specified channels' input ranges to output ranges. This version of the filter processes only images with 16 bpp colour planes. See LevelsLinear for 8 bpp version.

The filter accepts 16 bpp grayscale and 48/64 bpp colour images for processing.

Sample usage:

CopyC#

// create filter
LevelsLinear16bpp filter = new LevelsLinear16bpp( );
// set ranges
filter.InRed   = new IntRange( 3000, 42000 );
filter.InGreen = new IntRange( 5000, 37500 );
filter.InBlue  = new IntRange( 1000, 60000 );
// apply the filter
filter.ApplyInPlace( image );
