 # Didée: - Speed Boost, Updated: 11th May 2007
 # Dogway - added protection option. 12-May-2011
 # A.SONY - added high bit support and others. 31-Mar-2017
 #
 #  * requires mt_masktools v2 in avs2.5 and masktools 2.2.17 in avs 2.6 or avs+
 #  * requires yuv input
 #
 #
 #
 # Parameters are:
 #  strength (integer)  - Line darkening amount, 0-256. Default 48. Represents the _maximum_ amount
 #                        that the luma will be reduced by, weaker lines will be reduced by
 #                        proportionately less.
 #  prot     (integer)  - Prevents the darkest lines from being darkened. Protection acts as a threshold.
 #                        Values range from 0 (no prot) to ~50 (protect everything). Default 5.
 #  luma_cap (integer)  - value from 0 (black) to 255 (white), used to stop the darkening
 #                        determination from being 'blinded' by bright pixels, and to stop grey
 #                        lines on white backgrounds being darkened. Any pixels brighter than
 #                        luma_cap are treated as only being as bright as luma_cap. Lowering
 #                        luma_cap tends to reduce line darkening. 255 disables capping. Default 191.
 #  threshold (integer) - any pixels that were going to be darkened by an amount less than
 #                        threshold will not be touched. setting this to 0 will disable it, setting
 #                        it to 4 (default) is recommended, since often a lot of random pixels are
 #                        marked for very slight darkening and a threshold of about 4 should fix
 #                        them. Note if you set threshold too high, some lines will not be darkened
 #  thinning (integer)  - optional line thinning amount, 0-256. Setting this to 0 will disable it,
 #                        which is gives a _big_ speed increase. Note that thinning the lines will
 #                        inherently darken the remaining pixels in each line a little. Default 0.
 #
 # Changelog:
 #  1.43 - update to masktools 2.2.17
 #  1.42 - added high bit support in avs+ and others Optmized
 #  1.4  - added protection option. Prevents darkest lines to be over darkened thus creating artifacts (i.e. aliasing, clipping...)
 #       - Optmized the code as suggested by Didée for possible faster processing. It also deals with the green screen bug.
 #  1.3  - added ability to thin lines, now runs much slower unless thinning=0. Changed the defaults (again)
 #  1.2  - huge speed increase using yv12lutxy =)
 #       - weird darkening issues gone (they were caused by yv12layer)
 #       - show option no longer available due to optimizations. Use subtract() instead
 #  1.1  - added luma_cap option
 #  1.0  - initial release
 #
