Struct tfm::Header

pub struct Header {
    pub checksum: Option<u32>,
    pub design_size: Number,
    pub design_size_valid: bool,
    pub character_coding_scheme: Option<String>,
    pub font_family: Option<String>,
    pub seven_bit_safe: Option<bool>,
    pub face: Option<Face>,
    pub additional_data: Vec<u32>,
}

The TFM header, which contains metadata about the file.

This is defined in TFtoPL.2014.10.

Fields

checksum: Option<u32>

The font checksum, if specified.

In .tfm files checksums are always specified because the format has no way to omit a checksum.

In .pl files checksums are specified if the CHECKSUM node appears. If no checksum is specified in a .pl file, pltotf calculates the correct value and writes that.

In TeX82, this is stored in the font_check array (TeX82.2021.549).

design_size: Number

In TeX82, this is stored in the font_dsize array (TeX82.2021.549).

design_size_valid: bool

character_coding_scheme: Option<String>

font_family: Option<String>

seven_bit_safe: Option<bool>

face: Option<Face>

additional_data: Vec<u32>

The TFM format allows the header to contain arbitrary additional data.

Implementations

impl Header

pub fn pl_default() -> Header

Returns the default header when parsing property list files.

This is defined in PLtoTF.2014.70.

pub fn tfm_default() -> Header

Returns the default header when parsing .tfm files.

This is defined in PLtoTF.2014.70.

Trait Implementations

impl Clone for Header

fn clone(&self) -> Header

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Header

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

Formats the value using the given formatter.

impl Default for Header

fn default() -> Header

Returns the “default value” for a type.

impl PartialEq<Header> for Header

fn eq(&self, other: &Header) -> 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.

impl Eq for Header

impl StructuralEq for Header

impl StructuralPartialEq for Header
