Detailed Description

A Pango::Coverage represents a map from ISO-10646 character point to Pango::Coverage::Level.

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. Pango::Coverage holds this information.

Member Enumeration Documentation

Level

enum class Pango::Coverage::Level

strong

Enumerator
NONE	The character is not representable with the font.
FALLBACK	The character is represented in a way that may be comprehensible but is not the correct graphical form. For instance, a Hangul character represented as a a sequence of Jamos, or a Latin transliteration of a Cyrillic word.
APPROXIMATE	The character is represented as basically the correct graphical form, but with a stylistic variant inappropriate for the current script.
EXACT	The character is represented as the correct graphical form.

Member Function Documentation

create()

static

get()

Level Pango::Coverage::get

(

int

index

)

const

Determine whether a particular index is covered by coverage.

Parameters

index

The index to check.

Returns

The coverage level of coverage for character index.

gobj() [1/2]

PangoCoverage * Pango::Coverage::gobj

(

)

Provides access to the underlying C instance.

gobj() [2/2]

const PangoCoverage * Pango::Coverage::gobj

(

)

const

Provides access to the underlying C instance.

gobj_copy()

PangoCoverage * Pango::Coverage::gobj_copy

(

)

const

Provides access to the underlying C instance. The caller is responsible for unrefing it. Use when directly setting fields in structs.

operator delete()

void Pango::Coverage::operator delete ( void *  , std::size_t    )

protected

operator=()

Coverage & Pango::Coverage::operator= ( const Coverage &  )

delete

reference()

void Pango::Coverage::reference

(

)

const

Increment the reference count for this object.

You should never need to do this manually - use the object via a RefPtr instead.

set()

void Pango::Coverage::set	(	int	index,
		Level	level
	)

Modify a particular index within coverage.

Parameters

index	The index to modify.
level	The new level for index.

unreference()

void Pango::Coverage::unreference

(

)

const

Decrement the reference count for this object.

You should never need to do this manually - use the object via a RefPtr instead.

wrap()

Glib::RefPtr< Pango::Coverage > wrap ( PangoCoverage *  object, bool  take_copy = false  )

related

A Glib::wrap() method for this object.

Parameters

object	The C instance.
take_copy	False if the result should take ownership of the C instance. True if it should take a new copy or ref.

Returns

A C++ instance that wraps this C instance.
