DH_HexRGBtoRGB

Function:
Converts HTML-style hexadecimal RGB numbers, such as FFFFFF for white, and FF0000 for red, to Windows COLORREF RGB format, for use by other DH sub-control modules with color inputs. The module is bidirectional.


 Left-hand side pin:

Hex RGB - 6-digit hexadecimal number of the form RRGGBB, where RR, GG, and BB are the color's red, green, and blue components, respectively, each on a scale of 0x00 - 0xFF.


Right-hand side pin:

RGB - Windows COLORREF RGB value corresponding to the Hex RGB input.

 

DH_HSxToRGB

Function:

Converts between HSV (HSB) and HSL color values and the Windows COLORREF RGB format used by other DH sub-control modules with color inputs. The module is bidirectional.



 Left-hand side pins:

H - The color's hue value, on a scale determined by the Scale Maxima parameter (see below).

S - The color's saturation value, on a scale determined by the scale Maxima parameter.

B/V/L - The color's brightness or luminance value, on a scale determined by the Scale Maxima parameter.


Right-hand side pin:

RGB - Windows COLORREF value corresponding to the HSV (HSB) or HSL input.
 

Parameters: (right-click Properties)

Scale Maxima - Selects the maximum values for each of the H, S and B/V/L scales, as used in some common software:

  •  1-1-1 -  Each parameter is expressed as a number between 0.0 and 1.0. The SynthEdit™ Tinted Bitmap Image module uses this scale with HSB and gamma correction.
     

  • 360-100-100 - Measures hue on a scale of 0 - 360°, and saturation and brightness as percents, 0 - 100%. Used by PhotoShop™ (HSB).
     

  • 240-240-240 - Measures all 3 parameters on a scale of 0 - 240. Used by Windows™ color selection dialogs (HSL).
     

  • 255-255-255 - Measures all 3 parameters on a scale of 0 - 255. Used by Paint Shop Pro™ (HSL).

Color Space - Selects the HSV (HSB) or HSL color model.

Gamma Correction - On or Off. This is the same gamma correction used by the SE Tinted Bitmap Image. Thanks to Jeff McClintock for making the source code for this available.
