Implementations

impl<'a> Cpal<'a>

pub fn version(&self) -> u16

Table version number (=0).

pub fn num_palette_entries(&self) -> u16

Number of palette entries in each palette.

pub fn num_palettes(&self) -> u16

Number of palettes in the table.

pub fn num_color_records(&self) -> u16

Total number of color records, combined for all palettes.

pub fn color_records_array_offset(&self) -> Nullable<Offset32>

Offset from the beginning of CPAL table to the first ColorRecord.

pub fn color_records_array( &self, ) -> Option<Result<&'a [ColorRecord], ReadError>>

Attempt to resolve color_records_array_offset.

pub fn color_record_indices(&self) -> &'a [BigEndian<u16>]

Index of each palette’s first color record in the combined color record array.

pub fn palette_types_array_offset(&self) -> Option<Nullable<Offset32>>

Offset from the beginning of CPAL table to the Palette Types Array.

This is an array of 32-bit flag fields that describe properties of each palette.

pub fn palette_types_array( &self, ) -> Option<Result<&'a [BigEndian<PaletteType>], ReadError>>

Attempt to resolve palette_types_array_offset.

pub fn palette_labels_array_offset(&self) -> Option<Nullable<Offset32>>

Offset from the beginning of CPAL table to the Palette Labels Array.

This is an array of ‘name’ table IDs (typically in the font-specific name ID range) that specify user interface strings associated with each palette. Use 0xFFFF if no name ID is provided for a palette.

pub fn palette_labels_array( &self, ) -> Option<Result<&'a [BigEndian<u16>], ReadError>>

Attempt to resolve palette_labels_array_offset.

pub fn palette_entry_labels_array_offset(&self) -> Option<Nullable<Offset32>>

Offset from the beginning of CPAL table to the Palette Entry Labels Array.

This is an array of ‘name’ table IDs (typically in the font-specific name ID range) that specify user interface strings associated with each palette entry, e.g. “Outline”, “Fill”. This set of palette entry labels applies to all palettes in the font. Use 0xFFFF if no name ID is provided for a palette entry.

pub fn palette_entry_labels_array( &self, ) -> Option<Result<&'a [BigEndian<NameId>], ReadError>>

Attempt to resolve palette_entry_labels_array_offset.
