## Member Function Documentation

component_type const& blue | ( | RGBIterator const & | rgb,
|  | DIFFERENCE | d |
| ) |  |  | const

Get value of the blue component at an offset

component_type const& blue | ( | RGBIterator const & | rgb | ) | const

Get value of the blue component

component_type const& green | ( | RGBIterator const & | rgb,
|  | DIFFERENCE | d |
| ) |  |  | const

Get value of the green component at an offset

component_type const& green | ( | RGBIterator const & | rgb | ) | const

Get value of the green component

component_type const& red | ( | RGBIterator const & | rgb,
|  | DIFFERENCE | diff |
| ) |  |  | const

Get value of the red component at an offset

component_type const& red | ( | RGBIterator const & | rgb | ) | const

Get value of the red component

template<class V, class RGBIterator, class DIFFERENCE>
void setBlue | ( | V | value,
|  | RGBIterator const & | rgb,
|  | DIFFERENCE | d |
| ) |  |  | const

Set value of the blue component at an offset. The type `V` of the passed in `value` is automatically converted to `component_type`.

template<class V, class RGBIterator>
void setBlue | ( | V | value,
|  | RGBIterator const & | rgb |
| ) |  |  | const

Set value of the blue component. The type `V` of the passed in `value` is automatically converted to `component_type`.

template<class V, class RGBIterator, class DIFFERENCE>
void setGreen | ( | V | value,
|  | RGBIterator const & | rgb,
|  | DIFFERENCE | d |
| ) |  |  | const

Set value of the green component at an offset. The type `V` of the passed in `value` is automatically converted to `component_type`.

template<class V, class RGBIterator>
void setGreen | ( | V | value,
|  | RGBIterator const & | rgb |
| ) |  |  | const

Set value of the green component. The type `V` of the passed in `value` is automatically converted to `component_type`.

template<class V, class RGBIterator, class DIFFERENCE>
void setRed | ( | V | value,
|  | RGBIterator const & | rgb,
|  | DIFFERENCE | diff |
| ) |  |  | const

Set value of the red component at an offset. The type `V` of the passed in `value` is automatically converted to `component_type`.

template<class V, class RGBIterator>
void setRed | ( | V | value,
|  | RGBIterator const & | rgb |
| ) |  |  | const

Set value of the red component. The type `V` of the passed in `value` is automatically converted to `component_type`.
