Struct SpotColor 

pub struct SpotColor {
    pub color_name: String,
    pub knockout: bool,
    pub spotcolor_name: String,
    pub screen_frequency: NonNegativeF64,
    pub screen_angle_deg: f64,
    /* private fields */
}

A named spot color with its own CMYK/RGB representation and screen parameters.

Fields

color_name: String

The display name of this color.

knockout: bool

Whether this color knocks out colors beneath it.

spotcolor_name: String

The internal spot-color name used in printing.

screen_frequency: NonNegativeF64

Screen ruling frequency (lines per inch).

screen_angle_deg: f64

Screen ruling angle in degrees.

Implementations

impl SpotColor

pub fn new( color_name: impl Into<String>, spotcolor_name: impl Into<String>, cmyk: Cmyk, ) -> Self

Create a new spot color with the given name and CMYK values.

The RGB mode defaults to FromCmyk and screen parameters to 150.0 frequency and 0.0 angle.

pub fn get_cmyk(&self) -> Result<Cmyk, Error>

Get the effective CMYK value of this spot color.

Errors

Returns Error::ColorError if the color modes do not define a valid CMYK value.

pub fn get_rgb(&self) -> Result<Rgb, Error>

Get the effective RGB value of this spot color.

Errors

Returns Error::ColorError if the color modes do not define a valid RGB value.

pub fn set_cmyk_mode(&mut self, new: CmykMode) -> Result<(), Error>

Set the CMYK derivation mode. Fails if a circular dependency would be created.

Errors

Returns Error::ColorError if new is not valid for a spot color or would create a circular dependency with the RGB mode.

pub fn get_cmyk_mode(&self) -> CmykMode

Get the current CMYK derivation mode.

pub fn set_rgb_mode(&mut self, new: RgbMode) -> Result<(), Error>

Set the RGB derivation mode. Fails if a circular dependency would be created.

Errors

Returns Error::ColorError if new is not valid for a spot color or would create a circular dependency with the CMYK mode.

pub fn get_rgb_mode(&self) -> RgbMode

Get the current RGB derivation mode.

pub fn get_name(&self) -> &str

Get the display name of this spot color.

pub fn is_knockout(&self) -> bool

Returns true if this color knocks out colors beneath it.

Trait Implementations

impl Clone for SpotColor

Performs copy-assignment from source.

impl Debug for SpotColor

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl From<SpotColor> for Color
