/*  The Cleanup Process Reworked   -   EXPLANATION (by Daniele)

INTRODUCTION:

  The purpose of a Cleanup Process is hereby intended as the task of

transforming

  a fullcolor image (any bpp, matte supported*) into a TRasterCM32 -

  that is, a colormap image - given an externally specified palette of ink

colors to

  be recognized. No paint color is assumed at this stage.

  Typically, artists draw outlines using a black or dark color, whereas

different hues are

  used to mark lines that denote shadows or lights on characters.

  Additional processing steps include the ability to recognize and counter any

linear

  transformation in the image which is 'signaled' by the presence of (black)

pegbar holes,

  so that the countering linear transformation maps those peg holes in the usual

centered

  horizontal fashion.

  Post-processing include despeckling (ie removal or recoloration of little

blots with

  uniform color), and tones' brightness/contrast manipulation.

  (*) The image is first overed on top of a white background

CONSTRAINTS:

  We assume the following constraints throughout the process:

  - Palette colors:

    * Color 0 represents the PAPER color, and will just substitute it in the

colormap.

    * Colors with index >= 2 are MATCH-LINE colors, and their HUE ONLY (the H in

HSV coordinates)

    is essential to line recognition. The hue of image pixels is compared to

that of each

    matchline color - and the nearest matchline color is associated to that

pixel.

    If that associated matchline color is still too 'hue-distant' from the pixel

color

    (beyond a user-specified parameter), the pixel is ignored (ie associated to

paper).

    Furthermore, each matchline color also has a parameter corresponding to a

saturation

    threshold; pixels whose color's saturation is below the threshold specified

by the

    associated color are reassociated to the PAPER color.

    * Color 1 represents the OUTLINE color, and its VALUE (the V in HSV

coordinates) is

    assumed to be the image's lowest. Its H and S components are unused.

    Pixels whose value is below this value + a user-defined threshold parameter

are

    'outline-PRONE' pixels (even matchline-associated pixels can be).

    They are assumed to be full outline pixels if their CHROMA (S*V) is above a

    'Color threshold'. This condition lets the user settle how outline/matchline

    disputed pixels should be considered.

  - The Colormap tone for a pixel is extracted according to these rules:

    * Paper pixels are completely transparent (tone = 255).

    * Undisputed matchline colors build the tone upon the pixel's Saturation,

scaled

      so that 1.0 maps to 0, and the saturation threshold for that matchline

      color maps to 255.

    * Undisputed Outline colors do similarly, with the Value.

    * Disputed outline/matchline colors result in the blend PRODUCT of the above

tones.

      This makes the tone smoother on outline/matchline intersections.
