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.
◆ Coverage() [1/2]
Pango::Coverage::Coverage |
( |
| ) |
|
|
delete |
◆ Coverage() [2/2]
Pango::Coverage::Coverage |
( |
const Coverage& |
| ) |
|
|
delete |
◆ create() [1/2]
◆ create() [2/2]
◆ get()
Determine whether a particular index is covered by coverage.
- Parameters
-
- 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.
◆ max()
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
-
◆ operator delete()
void Pango::Coverage::operator delete |
( |
void * |
, |
|
|
std::size_t |
|
|
) |
| |
|
protected |
◆ operator=()
◆ 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()
Modify a particular index within coverage.
- Parameters
-
index | The index to modify. |
level | The new level for index. |
◆ to_bytes()
Convert the coverage map into a flat binary format.
- Returns
- An array of bytes representing the coverage map.
◆ 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()
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.
