Detailed Description

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

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.

static Glib::RefPtr<Coverage> Pango::Coverage::create ( const guchar *  bytes,
int  n_bytes 
) [static]

Convert data generated from pango_converage_to_bytes() back to a Pango::Coverage.

Parameters:
bytes Binary data representing a Pango::Coverage.
n_bytes The size of bytes in bytes.
Returns:
A newly allocated Pango::Coverage, or 0 if the data was invalid.

static Glib::RefPtr<Coverage> Pango::Coverage::create (  )  [static]

CoverageLevel 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.

const PangoCoverage* Pango::Coverage::gobj (  )  const

Provides access to the underlying C instance.

PangoCoverage* Pango::Coverage::gobj (  ) 

Provides access to the underlying C instance.

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.

void Pango::Coverage::max ( const Glib::RefPtr< Coverage >&  other  )  const

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.

Parameters:
other Another Pango::Coverage.

void Pango::Coverage::operator delete ( void *  ,
size_t   
) [protected]

void Pango::Coverage::reference (  )  const

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

Modify a particular index within coverage.

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

Glib::ArrayHandle<unsigned char> Pango::Coverage::to_bytes (  )  const

Convert the coverage map into a flat binary format.

Returns:
An array of bytes representing the coverage map.

void Pango::Coverage::unreference (  )  const

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.
