Struct embedded_text::style::height_mode::FitToText

pub struct FitToText;

Sets the height of the StyledTextBox to exactly fit the text.

Note: in this mode, vertical alignment is meaningless. Make sure to use TopAligned for efficiency.

Example: FitToText grows the TextBox.

use embedded_text::prelude::*;
use embedded_graphics::{fonts::Font6x8, pixelcolor::BinaryColor, prelude::*};

// This TextBox contains two lines of text, but is 1px high
let text_box = TextBox::new(
    "Two lines\nof text",
    Rectangle::new(Point::zero(), Point::new(59, 0)),
);

// Set style, use 6x8 font so the 2 lines are 16px high.
let style = TextBoxStyleBuilder::new(Font6x8)
    .height_mode(FitToText)
    .text_color(BinaryColor::On)
    .build();

// FitToText grows the TextBox to the height of the text
let size = text_box.into_styled(style).size();
assert_eq!(size, Size::new(60, 16));

Example: FitToText also shrinks the TextBox.

use embedded_text::prelude::*;
use embedded_graphics::{fonts::Font6x8, pixelcolor::BinaryColor, prelude::*};

// This TextBox contains two lines of text, but is 1px high
let text_box = TextBox::new(
    "Two lines\nof text",
    Rectangle::new(Point::zero(), Point::new(59, 59)),
);

// Set style, use 6x8 font so the 2 lines are 16px high.
let style = TextBoxStyleBuilder::new(Font6x8)
    .height_mode(FitToText)
    .text_color(BinaryColor::On)
    .build();

// FitToText shrinks the TextBox to the height of the text
let size = text_box.into_styled(style).size();
assert_eq!(size, Size::new(60, 16));
