Recommended display color, red intensity, of a special value

Description :

The recommended display color of a special value is useful to deliver a kind of color palette (or look up table) when pixel intensity values have a special meaning such as a class number. This is particularly used in the case of thematic classified images.

The RED_LEVEL gives the recommended color for the red intensity of the current special value (RGB color model). It ranges from 0.0 to 1.0. 0.0 is black and 1.0 is maximum intensity (this needs to be converted to actual color components which depends on the display device).

Example :
 
<Special_Value_Color>
<!-- Dirty green, opaque --->
   <RED_LEVEL >0.1</RED_LEVEL>
   <GREEN_LEVEL>1.0</GREEN_LEVEL>
   <BLUE_LEVEL>0.2</BLUE_LEVEL>
</Special_Value_Color>

or

<Special_Value_Color>
<!-- White, semi-transparent --->
   <RED_LEVEL >1.O</RED_LEVEL>
   <GREEN_LEVEL>1.0</GREEN_LEVEL>
   <BLUE_LEVEL>1.0</BLUE_LEVEL>
   <ALPHA_LEVEL>0.5</ALPHA_LEVEL>
</Special_Value_Color>
or

<Special_Value_Color>
<!-- totally transparent, color can be anything --->
   <RED_LEVEL >0.0</RED_LEVEL>
   <GREEN_LEVEL>0.0</GREEN_LEVEL>
   <BLUE_LEVEL>0.0</BLUE_LEVEL>
   <ALPHA_LEVEL>0.0</ALPHA_LEVEL>
</Special_Value_Color>
