Struct pdf_writer::writers::ColorSpace

pub struct ColorSpace<'a> { /* fields omitted */ }

Writer for a color space.

This struct is created by PdfWriter::color_space, Shading::color_space, ImageXObject::color_space and Group::color_space.

Implementations

impl ColorSpace<'_>

CIE-based color spaces.

pub fn cal_rgb(
    self,
    white_point: [f32; 3],
    black_point: Option<[f32; 3]>,
    gamma: Option<f32>,
    matrix: Option<[f32; 9]>
)

Write a CalRGB color space.

pub fn cal_gray(
    self,
    white_point: [f32; 3],
    black_point: Option<[f32; 3]>,
    gamma: Option<f32>
)

Write a CalGray color space.

pub fn lab(
    self,
    white_point: [f32; 3],
    black_point: Option<[f32; 3]>,
    range: Option<[f32; 4]>
)

Write a Lab color space.

impl ColorSpace<'_>

Device color spaces.

pub fn device_rgb(self)

Write a DeviceRGB color space.

pub fn device_cmyk(self)

Write a DeviceCMYK color space.

pub fn device_gray(self)

Write a DeviceGray color space.

impl ColorSpace<'_>

Special color spaces.

pub fn separation(self, color_name: Name<'_>, base: Name<'_>, tint: Ref)

Write a Separation color space. PDF 1.2+.

pub fn device_n<'n>(
    self,
    names: impl IntoIterator<Item = Name<'n>>,
    alternate_space: Name<'_>,
    tint: Ref
)

Write a DeviceN color space. PDF 1.3+.

pub fn indexed(self, base: Name<'_>, hival: i32, lookup: &[u8])

Write an Indexed color space. PDF 1.2+.

The length of the lookup slice must be the product of the dimensions of the base color space and (hival + 1) and hival shall be at most 255.

pub fn pattern(self, base: Name<'_>)

Write a Pattern color space for uncolored patterns. PDF 1.2+.

The base attribute is the color space in which the pattern color is specified upon use.
