RgbAlpha50

NewColour = RgbAlpha50(RGBValue1, RGBValue2)

Parameters:

RGBValue1 = An RGB Colour Value
RGBValue2 = An RGB Colour Value

Returns:

NewColour = The result colour after this operation

The RgbAlpha50() function performs a 50/50 Alpha Blend between the RGB channels of two colours. So the colours are merged together.

FACTS:

* You can find some more detailed examples in the Projects/Examples/Colours folder of your PlayBASIC installation.

Mini Tutorial:

This example shows the effect of the Rgb Alpha 50 colour operation.

  ColourA=RGB(100,110,120)
  ColourB=RGB(50,60,70)

  PrintHEading("Rgb Alpha 50")
  PrintColour( ColourA)
  PrintColour( ColourB)
  PrintColour( rgbalpha50(ColourA,ColourB))

  // Demostrate this visually
  BoxC 100,100,200,200,true,ColourA
  BoxC 150,150,250,250,true,ColourB
  BoxC 150,150,200,200,true,rgbalpha50(ColourA,ColourB)

; Split the colour into and R,G,B fields and display it
Function PrintColour(ThisColour)
  r=RgbR(ThisCOlour)

  b=RgbB(ThisCOlour)
  Print  Str$(r)+","+Str$(g)+","+Str$(b)
