Detailed Description

Representation of a pixel on a display or a plane.

Coordinates are non-negative, values are decimal.

Constructor & Destructor Documentation

Pixel() [1/2]

osmscout::Pixel::Pixel ( )

inlinedefault

The default constructor creates an uninitialized instance (for performance reasons).

Referenced by operator!=(), operator<(), and operator==().

Pixel() [2/2]

osmscout::Pixel::Pixel ( uint32_t x, uint32_t y )

inline

References x, and y.

Member Function Documentation

GetDisplayText()

std::string osmscout::Pixel::GetDisplayText

(

)

const

References x, and y.

Referenced by operator<<().

GetId()

uint64_t osmscout::Pixel::GetId ( ) const

inline

Returns a unique number based on the coordinates of the pixel.

The bits of the coordinates are projected onto one number by interleaving the bits of the coordinates. Coordinates close in 2D space are thus likely clos ein one dimensional space, too.

References osmscout::InterleaveNumbers(), x, and y.

operator!=()

bool osmscout::Pixel::operator!= ( const Pixel & other ) const

inline

References Pixel(), x, and y.

operator<()

bool osmscout::Pixel::operator< ( const Pixel & other ) const

inline

References Pixel(), x, and y.

operator<<()

std::ostream & osmscout::Pixel::operator<< ( std::ostream & stream ) const

inline

References GetDisplayText().

operator==()

bool osmscout::Pixel::operator== ( const Pixel & other ) const

inline

References Pixel(), x, and y.
