Member Function Documentation

operator[]() [1/2]

CVB_FORCE_INLINE const PixelType & operator[] ( int  y ) const

inlinenoexcept

Row access.

Precondition

y must be between 0 and less than the allowed height.

Parameters

[in]

y

Pixel row.

Returns

Pointer to the pixel at the row y.

operator[]() [2/2]

CVB_FORCE_INLINE PixelType & operator[] ( int  y )

inlinenoexcept

Row access.

Precondition

y must be between 0 and less than the allowed height.

Parameters

[in]

y

Pixel row.

Returns

Pointer to the pixel at the row y.

Set() [1/2]

CVB_FORCE_INLINE auto Set ( int  y, const FromPixelType &  value  ) -> std::enable_if_t<!std::is_convertible<remove_cvref_t<FromPixelType>, remove_cvref_t<PixelType>>::value, void>

inlinenoexcept

Row setter.

Supports any input type for value for which get<I>() is overloaded and has sufficiently many values.

Precondition

y must be between 0 and less than the allowed height.

Parameters

[in]	y	Pixel row.
[in]	value	New pixel value.

Set() [2/2]

CVB_FORCE_INLINE void Set ( int  y, const PixelType &  value  )

inlinenoexcept

Row setter.

Supports any input type for value for which get<I>() is overloaded and has sufficiently many values.

Precondition

y must be between 0 and less than the allowed height.

Parameters

[in]	y	Pixel row.
[in]	value	New pixel value.
