Struct fdg_img::style::TextStyle

pub struct TextStyle<'a> {
    pub font: FontDesc<'a>,
    pub color: BackendColor,
    pub pos: Pos,
}

Style of a text

Fields

font: FontDesc<'a>

The font description

color: BackendColor

The text color

pos: Pos

The anchor point position

Implementations

impl<'a> TextStyle<'a>

pub fn color<C>(&self, color: &'a C) -> TextStyle<'a>where
    C: Color,

Sets the color of the style.

• color: The required color
• returns The up-to-dated text style

use plotters::prelude::*;

let style = TextStyle::from(("sans-serif", 20).into_font()).color(&RED);

pub fn transform(&self, trans: FontTransform) -> TextStyle<'a>

Sets the font transformation of the style.

• trans: The required transformation
• returns The up-to-dated text style

use plotters::prelude::*;

let style = TextStyle::from(("sans-serif", 20).into_font()).transform(FontTransform::Rotate90);

pub fn pos(&self, pos: Pos) -> TextStyle<'a>

Sets the anchor position.

• pos: The required anchor position
• returns The up-to-dated text style

use plotters::prelude::*;
use plotters::style::text_anchor::{Pos, HPos, VPos};

let pos = Pos::new(HPos::Left, VPos::Top);
let style = TextStyle::from(("sans-serif", 20).into_font()).pos(pos);
