csRGBpixel Struct Reference

An RGB pixel. More...

#include <rgbpixel.h>

List of all members.

Public Methods

csRGBpixel ()

Constructor (initialize to zero, alpha to 255).

csRGBpixel (const csRGBpixel &p)

Copy constructor.

csRGBpixel (const csRGBcolor &c)

Yet another copy constructor.

csRGBpixel (int r, int g, int b)

Initialize the pixel with some R/G/B value.

bool operator== (const csRGBcolor &c) const

Compare with an csRGBcolor.

bool operator== (const csRGBpixel &p) const

Compare with an csRGBpixel (including alpha value).

bool operator!= (const csRGBcolor &c) const

Check if the csRGBpixel is not equal to an csRGBcolor.

bool operator!= (const csRGBpixel &p) const

Check if this csRGBpixel is not equal to another csRGBpixel (including alpha).

operator csRGBcolor () const

Construct an csRGBcolor from this csRGBpixel.

bool eq (const csRGBpixel &p) const

Compare with another csRGBpixel, but don't take alpha into account.

int Intensity ()

Get the pixel intensity.

unsigned char Luminance ()

void Set (const int r, const int g, const int b)

Assign given red/green/blue values to this pixel.

void Set (const int r, const int g, const int b, const int a)

Assign given red/green/blue/alpha values to this pixel.

void Set (const csRGBpixel &p)

Public Attributes

unsigned char red

The red, green, blue and alpha components.

unsigned char green

The red, green, blue and alpha components.

unsigned char blue

The red, green, blue and alpha components.

unsigned char alpha

The red, green, blue and alpha components.

Detailed Description

An RGB pixel.

In addition to R,G,B color components this structure also contains the Alpha channel component, which is used in images (that potentially have an alpha channel).
