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).

Pixel() [2/2]

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

GetDisplayText()

std::string osmscout::Pixel::GetDisplayText

const

References x, and y.

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.

operator<()

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

operator==()
