## Member Function Documentation

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

Get value of the red component

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`.

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

Get value of the red component at an offset

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`.

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

Get value of the green component

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`.

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

Get value of the green component at an offset

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`.

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

Get value of the blue component

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`.

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

Get value of the blue component at an offset

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`.
