## Detailed Description

### template<class T>
class irr::core::dimension2d< T >

Specifies a 2 dimensional size.

Definition at line 20 of file dimension2d.h.

## 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 | ) | `[inline]`

Definition at line 330 of file vector2d.h.

template<class T>
template<class U >

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

Use this constructor only where you are sure that the conversion is valid.

Definition at line 33 of file dimension2d.h.

## Member Function Documentation

template<class T>

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

Get area.

Definition at line 125 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.

Returns:
  Interpolated dimension.

Definition at line 191 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.
