.COLOR SET BRUSH METAL

Sets the strength of the texture to create a Brushed Metal Effect for the "current" Color Object.

Usage:

      PASS         <texture_strength>         FIELD            SHARE? N
      GOSUB    0CD .COLOR SET BRUSH METAL
      *        Check for error
      IF       0CD .COLOR SET BRUSH METAL     NE

Description:

Sets the strength of the texture to create a Brushed Metal Effect for the "current" Color Object. The brightness of the color will vary smoothly across the image, so as to produce a shiny effect. The color will then be modulated with a horizontal texture to create the brushed effect. The modulation period will be the same as the size of the image, so this subroutine is best use to create background colors.

<texture_strength> must be one of: None, Light, Medium, or Strong. If blank or not passed, it will default to None. Note that this does not change the color of the object, just applies a brushed metal effect.

This routine is usually called in conjunction with .COLOR SET METAL.

See ColorSpec for more information on working with colors.
