class Pango::Coverage

Overview

A Pango::Coverage structure is a map from Unicode characters to Pango::CoverageLevel values.

It is often necessary in Pango to determine if a particular font can represent a particular character, and also how well it can represent that character. The Pango::Coverage is a data structure that is used to represent that information. It is an opaque structure with no public fields.

Defined in:

lib/gi-crystal/src/auto/pango-1.0/coverage.cr

Instance Method Detail

def ==(other : self) #
Description copied from class Reference

Returns true if this reference is the same as other. Invokes same?.


def copy : Pango::Coverage #

Copy an existing Pango::Coverage.

def get(index_ : Int32) : Pango::CoverageLevel #

Determine whether a particular index is covered by coverage.


[View source]
def hash(hasher) #
Description copied from class Reference

See Object#hash(hasher)


def max(other : Pango::Coverage) : Nil #

Set the coverage for each index in coverage to be the max (better) value of the current coverage for the index and the coverage for the corresponding index in other.

DEPRECATED


[View source]
def ref : Pango::Coverage #

Increase the reference count on the Pango::Coverage by one.

DEPRECATED


[View source]
def set(index_ : Int32, level : Pango::CoverageLevel) : Nil #

Modify a particular index within coverage


[View source]
def to_bytes(bytes : Bytes) : Nil #

Convert a Pango::Coverage structure into a flat binary format.

DEPRECATED


[View source]
def to_bytes(*bytes : UInt8) #

[View source]
def unref : Nil #

Decrease the reference count on the Pango::Coverage by one.

If the result is zero, free the coverage and all associated memory.
