Struct tfm::format::CharDimensions

pub struct CharDimensions {
    pub width_index: WidthIndex,
    pub height_index: u8,
    pub depth_index: u8,
    pub italic_index: u8,
}

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

Trait Implementations

impl Clone for CharDimensions

fn clone(&self) -> CharDimensions

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for CharDimensions

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

Formats the value using the given formatter.

impl PartialEq<CharDimensions> for CharDimensions

fn eq(&self, other: &CharDimensions) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
