Detailed Description

This class was created to hold HSV values at a better resolution than this is possible with QColor. It can however be used for RGB values also, but in this it is significantly slower than QColor.

Constructor & Destructor Documentation

rColor::rColor (   )

This constructor takes no arguments and sets the current color to an opaque white. Here is the call graph for this function:

rColor::rColor (  int  h, int  s, int  v, int  a = 255 )

Here is the call graph for this function:

Member Function Documentation

void rColor::createRGB (   )  [private]

Converts the current color to an RGB triple.

int rColor::getAlpha (   )  const [inline]

void rColor::getHSV (  int *  h, int *  s, int *  v )  const

Returns the current values for hue, saturation, and value in the parameters.

void rColor::getRGB (  int *  r, int *  g, int *  b )

Returns the RGB triple for the current color. Here is the call graph for this function:

int rColor::gray (   )

Returns a gray value based on the current color in the range of 0 ... 255. Here is the call graph for this function:

void rColor::normalizeHSV (  int *  , int *  , int *  )  [private]

rColor & rColor::operator= (  const rColor &  c  )

Copies the values for hue, saturation and value from c. If the values for red, green and blue are useable, they are copied too. If not, only the corresponding flag dirty is set.

bool rColor::operator== (  const rColor &  c  )  const [inline]

Returns true if the components hue, saturation, value and alpha of the compared rColors are the same.

unsigned int rColor::rgb (   )

Returns a pixel value for the current color, including alpha value. Here is the call graph for this function:

void rColor::setAlpha (  int  a  )  [inline]

void rColor::setHSV (  int  h, int  s, int  v )

Sets the current color to a new HSV triple. Here is the call graph for this function:

void rColor::setRGB (  int  r, int  g, int  b )

Sets the current color to the values provided for r, g, and b.
