Expand description

Data about one character in a .tfm file.

Fields§

§width_index: WidthIndex

Index of the width of this character in the widths array.

In valid TFM files, this index will always be non-zero. This is because if the width index is zero it means there is no data for the character in the file. In this case the other indices (height, etc.) are necessarily zero. See TFtoPL.2014.? (where blocks of data with a zero width index are skipped) and PLtoTF.2014.? (where missing characters are written with all indices 0).

There is one edge case where this index can be zero. This is if the width index is invalid. In this case tftopl essentially sets the width index to 0.

Note that even if a character doesn’t have dimensions, it can still have a tag.

§height_index: u8

Index of the height of this character in the height array.

§depth_index: u8§italic_index: u8

fn fg(&self, value: Color) -> Painted<&T>

use yansi::{Paint, Color};

painted.fg(Color::White);

Set foreground color to white using white().
