Primary color class that stores data for red (R), green (G), and blue (B). The value stored in [[IC_Python_API:RLPy_RRgb|RRgb]] ranges from 0-1, which represents 0 to 255 in color value.  You can swtich between these two representations in different ways;  For example, the range of values retrieved by [[#R ( self, args )|R]] is 0 to 1, and the range of values retrieved by [[#Red ( self )|Red]] is 0 to 255.  In addition, preset colors are provided for direct usage:

Description

Primary color class that stores data for red (R), green (G), and blue (B). The value stored in RRgb ranges from 0-1, which represents 0 to 255 in color value. You can swtich between these two representations in different ways; For example, the range of values retrieved by R is 0 to 1, and the range of values retrieved by Red is 0 to 255. In addition, preset colors are provided for direct usage:

Constant Value
RLPy.RRgb.BLACK RLPy.RRgb(0, 0, 0)
RLPy.RRgb.WHITE RLPy.RRgb(1, 1, 1)
RLPy.RRgb.RED RLPy.RRgb(1, 0, 0)
RLPy.RRgb.GREEN RLPy.RRgb(0, 1, 0)
RLPy.RRgb.BLUE RLPy.RRgb(0, 0, 1)
RLPy.RRgb.YELLOW RLPy.RRgb(1, 1, 0)
RLPy.RRgb.CYAN RLPy.RRgb(0, 1, 1)
RLPy.RRgb.MAGENTA RLPy.RRgb(1, 0, 1)

RRgb does not include alpha data. Use RColor instead if alpha channel is needed. This class also provides ways to convert to other color formats: 

 1 # create color
 2 color_red1 = RLPy.RRgb(1, 0, 0)
 3 color_red2 = RLPy.RRgb()
 4 color_red2.From(255, 0, 0)
 5 color_red3 = RLPy.RRgb.RED
 6  
 7 # print color
 8 print( color_red1.R() )         # 1
 9 print( color_red1.Red() )       # 255
10  
11 # convert different format
12 print(hex(color1.ToXRGB()))     # 0xff0000
13 print(hex(color1.ToCOLORREF())) # 0xff

Clamp the RGB values to a range of 0 and 1. Values under 0 will become 0, and values over 1 will become 1.

Returns

This color saturated (RRgb) - RRgb
1 color1 = RLPy.RRgb(1.2, -0.3, 0.5)
2 color1.Saturate()              # (1, 0, 0.5)

ToCOLORREF ( self )

Output COLORREF data from this color (0xbbggrr).

See Also: FromCOLORREF

Returns

COLORREF color data - int
1 color1 = RLPy.RRgb(0, 0, 1)
2 print(int(color1.ToCOLORREF()))          # 0xff0000

ToVector3f ( self )

Output 3D vector data from this color.

Returns

3D vector color data - RVector3
1 color1 = RLPy.RRgb(0, 0, 1)
2 print(color1.ToVector3f())

ToXRGB ( self )

Output hexadecimal data from this color (0xrrggbb)

See Also: FromXRGB

Returns

Hexadecimal color data - int
1 color1 = RLPy.RRgb(0, 0, 1)
2 print(int(color1.ToXRGB()))              # 0xff
