Detailed Description

This structure defines the "logical position" of a tile in the 2D-document model. It is given by a (axis-aligned) rectangle (in the plane-pixel-coordinate-system) and the pyramid-level.

Constructor & Destructor Documentation

LogicalPositionInfo() [1/2]

imgdoc2::LogicalPositionInfo::LogicalPositionInfo ( double  x, double  y, double  w, double  h  )

inline

Constructor initializing the rectangle and setting the pyramid-level to zero.

Parameters

x	The x coordinate of the top left point.
y	The y coordinate of the top left point.
w	The width.
h	The height.

LogicalPositionInfo() [2/2]

imgdoc2::LogicalPositionInfo::LogicalPositionInfo ( double  x, double  y, double  w, double  h, int  pyrLvl  )

inline

Constructor.

Parameters

x	The x coordinate of the top left point.
y	The y coordinate of the top left point.
w	The width.
h	The height.
pyrLvl	The pyramid level.

Member Function Documentation

operator!=()

bool imgdoc2::LogicalPositionInfo::operator!= ( const LogicalPositionInfo &  rhs ) const

inline

Inequality operator (where the coordinates are compared with an epsilon).

Parameters

rhs	The right hand side.

Returns

True if the parameters are not considered equivalent.

operator==()

bool imgdoc2::LogicalPositionInfo::operator== ( const LogicalPositionInfo &  rhs ) const

inline

Equality operator (where the coordinates are compared with an epsilon).

Parameters

rhs	The right hand side.

Returns

True if the parameters are considered equivalent.
