## Detailed Description

An absolute RGB color.

## Constructor & Destructor Documentation

## Color() [1/3]

ipe::Color::Color | ( |  | ) |

inline

Default constructor.

## Color() [2/3]

Color::Color | ( | String | str | ) |

explicit

Construct a color from a string.

If only a single number is given, this is a gray value, otherwise red, green, and blue components must be given.

References ipe::Lex::eos(), iBlue, iGreen, and iRed.

## Color() [3/3]

Color::Color | ( | int | red,
|  | int | green,
|  | int | blue
| ) |  |

explicit

Construct a color.

Arguments red, green, blue range from 0 to 1000.

## save()

void Color::save | ( | Stream & | stream | ) | const

Save to stream.
