Parameters: r   Red componant. g   Green componant. b   Blue componant. a   Alpha componant. Definition at line 57 of file rgba.h. Member Function Documentation void NLMISC::CRGBA::avg2 ( const CRGBA & a, const CRGBA & b ) [inline]   Compute in this the average of 2 RGBA. Definition at line 166 of file rgba.h. void NLMISC::CRGBA::avg4 ( const CRGBA & a, const CRGBA & b, const CRGBA & c, const CRGBA & d ) [inline]   Compute in this the average of 4 RGBA. The average is "correct": +1 is added to the four color, to make a "round" like average.
