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: 

# create color
color_red1 = RLPy.RRgb(1, 0, 0)
color_red2 = RLPy.RRgb()
color_red2.From(255, 0, 0)
color_red3 = RLPy.RRgb.RED
 
# print color
print( color_red1.R() )         # 1
print( color_red1.Red() )       # 255
 
# convert different format
print(hex(color1.ToXRGB()))     # 0xff0000
print(hex(color1.ToCOLORREF())) # 0xff

Member Functions

B ( self, args )

Get the blue value of this color (0-1).

See Also: Blue

Returns

Value for the blue channel (0-1) - float
color1 = RLPy.RRgb(0, 0, 1)
print(color1.B())               # 1

Blue ( self )

Get the blue value of this color (0-255).

See Also: B

Returns

Value for the blue channel (0-255) - int
color1 = RLPy.RRgb(0, 0, 1)
print(color1.Blue())            # 255

From ( self, r, g, b )

Adjust color using 32 bit (0-255).

Parameters

r [IN] Red value (0-255) - int
g [IN] Green value (0-255) - int
b [IN] Blue value (0-255) - int

Returns

(0-255) color - RRgb
color1 = [[IC_Python_API:RLPy_RRgb|RRgb]]
color1.From(255, 0, 0)

FromCOLORREF ( self, arg2 )

Adjust color using COLORREF (0xbbggrr).

See Also: ToCOLORREF

Parameters

arg2 [IN] COLORREF data

Returns

Changed color - RRgb
color_red2 = [[IC_Python_API:RLPy_RRgb|RRgb]]
color_red2.FromCOLORREF(int(‘ff0000’, 16))

FromXRGB ( self, arg2 )

Assign this color using hexadecimal (0xrrggbb).

See Also: ToXRGB

Parameters

arg2 [IN] RGB hexadecimal value - HEX

Returns

Changed color - RRgb
color_red2 = [[IC_Python_API:RLPy_RRgb|RRgb]]
color_red2.FromXRGB(int(‘0000ff’, 16))

G ( self, args )

Get the green value of this color (0-1).

See Also: Green

Returns

Green value of this color (0-1) - float
color1 = RLPy.RRgb(0, 1, 0)
print(color1.G())               # 1

Green ( self )

Get the green value of this color (0-255).

See Also: G

Returns

Green value of this color (0-255) - int
color1 = RLPy.RRgb(0, 1, 0)

Normalize ( self )

Normalize RGB values so that their sum equals 1.

Returns

Normalized color - RRgb

print(color1.Red())            # 255

Saturate ( self )

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