Code: BlitzBasic

1. Const RALPHA = 24       ;Return Alpha when using RColor
2. Const RRED = 16 ;Return Red when using RColor
3. Const RGREEN = 8        ;Return Green when using RColor
4. Const RBLUE = 0 ;Return Blue when using RColor
5.  
6. ; IntColor returns an integer color useable by WritePixel() and WritePixelFast()
7. ; R = Red
8. ; G = Green
9. ; B = Blue
10. ; A = Alpha.
11. ; return = An integer color useable by functions such as WritePixel() and WritePixelFast()
12. Function IntColor(R,G,B,A=255)
13.         Return A Shl 24 Or R Shl 16 Or G Shl 8 Or B Shl 0
14. End Function
15.  
16. ; RColor returns the value of Red, Green, Blue, or Alpha in C.
17. ; c = An integer color returned by, for example, ReadPixelFast()
18. ; c = The amount of bits C should be shifted right to.  Valid constants are: RRED, RGREEN, RBLUE, RALPHA
19. ; return = An integer ranging from 0 to 255.
20. Function RColor%(c%,d%)
21.         Return c Shr d And 255 Shl 0
22. End Function
