## Constructor & Destructor Documentation

template<class T>

irr::core::dimension2d< T >::dimension2d | ( |  | ) | `[inline]`

Default constructor for empty dimension.

Definition at line 24 of file dimension2d.h.

template<class T>

irr::core::dimension2d< T >::dimension2d | ( | const T & | width,
|  | const T & | height
| ) |  | `[inline]`

Constructor with width and height.

Definition at line 26 of file dimension2d.h.

template<class T>

irr::core::dimension2d< T >::dimension2d | ( | const vector2d< T > & | other | ) |

Definition at line 333 of file vector2d.h.

template<class T>
template<class U >

irr::core::dimension2d< T >::dimension2d | ( | const dimension2d< U > & | other | ) | `[inline, explicit]`

## Member Function Documentation

template<class T>

T irr::core::dimension2d< T >::getArea | ( |  | ) | const`[inline]`

Get area.

Definition at line 130 of file dimension2d.h.

template<class T>

dimension2d<T> irr::core::dimension2d< T >::getInterpolated | ( | const dimension2d< T > & | other,
|  | f32 | d
| ) |  | const`[inline]`

Get the interpolated dimension.

Parameters:

  other | Other dimension to interpolate with.
  d | Value between 0.0f and 1.0f. d=0 returns other, d=1 returns this, values between interpolate.

Returns:
  Interpolated dimension.

Definition at line 196 of file dimension2d.h.

template<class T>

dimension2d<T> irr::core::dimension2d< T >::getOptimalSize | ( | bool | requirePowerOfTwo = `true`,
|  | bool | requireSquare = `false`,
|  | bool | larger = `true`,
|  | u32 | maxValue = `0`
| ) |  | const`[inline]`

Get the optimal size according to some properties.

This is a function often used for texture dimension calculations. The function returns the next larger or smaller dimension which is a power-of-two dimension (2^n,2^m) and/or square (Width=Height).

Parameters:

  requirePowerOfTwo | Forces the result to use only powers of two as values.
  requireSquare | Makes width==height in the result
  larger | Choose whether the result is larger or smaller than the current dimension. If one dimension need not be changed it is kept with any value of larger.
  maxValue | Maximum texturesize. if value > 0 size is clamped to maxValue

Returns:
  The optimal dimension under the given constraints.
