Detailed Description

Simple class for passing around pairs of small unsigned integers.

Use this for integer dimensions and points with limited range such as image sizes and pixel coordinates where a pair of floating point numbers is inefficient and illogical (i.e. the data is inherently integer). One of these can be passed in a single 32 bit integer register on common architectures.

Member Function Documentation

template<typename FLOAT_ARRAY >
static Uint16Pair Dali::Uint16Pair::FromFloatArray ( const FLOAT_ARRAY &  from) [static]

Creates an instance by rounding a floating point array to closest integers.

Uses a template to allow any vector type with operator [] to be converted in addition to plain arrays.

Since:
3.0, DALi version 1.0.0
Parameters:
[in]fromFloating point array
Returns:
Closest integer value
template<typename FLOAT_VECTOR_N_TYPE >
static Uint16Pair Dali::Uint16Pair::FromFloatVec2 ( const FLOAT_VECTOR_N_TYPE &  from) [static]

Creates an instance by rounding a floating point vector to closest integers.

Uses a template for loose coupling, to save a header include, and allow any vector type with .x and .y members to be converted.

Since:
3.0, DALi version 1.0.0
Parameters:
[in]fromFloating point vector2
Returns:
Closest integer value
