Static Public Member Functions | |
| template<typename FLOAT_VECTOR_N_TYPE > | |
| static Uint16Pair | FromFloatVec2 (const FLOAT_VECTOR_N_TYPE &from) |
| Creates an instance by rounding a floating point vector to closest integers. | |
| template<typename FLOAT_ARRAY > | |
| static Uint16Pair | FromFloatArray (const FLOAT_ARRAY &from) |
| Creates an instance by rounding a floating point array to closest integers. | |
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.
Default constructor for the (0, 0) tuple.
| Dali::Uint16Pair::Uint16Pair | ( | uint32_t | width, |
| uint32_t | height | ||
| ) |
Constructor taking separate x and y (width and height) parameters.
| [in] | width | The width or X dimension of the tuple. Make sure it is less than 65536 |
| [in] | height | The height or Y dimension of the tuple. Make sure it is less than 65536 |
| Dali::Uint16Pair::Uint16Pair | ( | const Uint16Pair & | rhs | ) |
Copy constructor.
| [in] | rhs | A reference to assign |
| 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.
| [in] | from | Floating point array |
| 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.
| [in] | from | Floating point vector2 |
