Subprograms & Entries

Reference 

function Reference 
(Font_Face: Cairo_Font_Face) return Cairo_Font_Face;
Font_Face: a Cairo_Font_Face, (may be Null_Font_Face in which case this function does nothing). Increases the reference count on Font_Face by one. This prevents Font_Face from being destroyed until a matching call to Cairo.Font_Face.Destroy is made. The number of references to a Cairo_Font_Face can be get using Cairo.Font_Face.Get_Reference_Count. Return value: the referenced Cairo_Font_Face.

Destroy 

procedure Destroy 
(Font_Face: Cairo_Font_Face);
Font_Face: a Cairo_Font_Face Decreases the reference count on Font_Face by one. If the result is zero, then Font_Face and all associated resources are freed. See Cairo.Font_Face.Reference.

Get_Reference_Count 

function Get_Reference_Count 
(Font_Face: Cairo_Font_Face) return Guint;
Font_Face: a Cairo_Font_Face Returns the current reference count of Font_Face. Return value: the current reference count of Font_Face. If the object is a nil object, 0 will be returned. Since: 1.4

Status 

function Status 
(Font_Face: Cairo_Font_Face) return Cairo_Status;
Font_Face: a Cairo_Font_Face Checks whether an error has previously occurred for this font face Return value: Cairo_Status_Success or another error such as Cairo_Status_No_Memory.

Get_Type 

function Get_Type 
(Font_Face: Cairo_Font_Face) return Cairo_Font_Type;
Font_Face: a font face This function returns the type of the backend used to create a font face. See Cairo_Font_Type for available types. Return value: The type of Font_Face. Since: 1.2

Get_User_Data 

function Get_User_Data 
(Font_Face: Cairo_Font_Face;
Key: access Cairo_User_Data_Key) return System.Address;
Font_Face: a Cairo_Font_Face Key: the address of the Cairo_User_Data_Key the user data was attached to Return user data previously attached to Font_Face using the specified key. If no user data has been attached with the given key this function returns System.Null_Address. Return value: the user data previously attached or System.Null_Address.

Set_User_Data 

function Set_User_Data 
(Font_Face: Cairo_Font_Face;
Key: access Cairo_User_Data_Key;
User_Data: System.Address;
Destroy: Cairo_Destroy_Func) return Cairo_Status;
Font_Face: a Cairo_Font_Face Key: the address of a Cairo_User_Data_Key to attach the user data to User_Data: the user data to attach to the font face Destroy: a Cairo_Destroy_Func which will be called when the font face is destroyed or when new user data is attached using the same key. Attach user data to Font_Face. To remove user data from a font face, call this function with the key that was used to set it and System.Null_Address for data. Return value: Cairo_Status_Success or Cairo_Status_No_Memory if a slot could not be allocated for the user data.

Toy_Font_Face_Create 

function Toy_Font_Face_Create 
(Family: Interfaces.C.Strings.chars_ptr;
Slant: Cairo_Font_Slant;
Weight: Cairo_Font_Weight) return   Cairo_Font_Face;
Family: a font Family name, encoded in UTF-8 Slant: the Slant for the font Weight: the Weight for the font Creates a font face from a triplet of family, slant, and weight. These font faces are used in implementation of the the Cairo_Context "toy" font API. If Family is the zero-length string "", the platform-specific default family is assumed. The default family then can be queried using Toy_Font_Face_Get_Family. The Cairo_Select_Font_Face function uses this to create font faces. See that function for limitations of toy font faces. Return value: a newly created Cairo_Font_Face. Free with Cairo.Font_Face.Destroy when you are done using it. Since: 1.8

Toy_Font_Face_Get_Family 

function Toy_Font_Face_Get_Family 
(Font_Face: Cairo_Font_Face) return      Interfaces.C.Strings.chars_ptr;
Font_Face: A toy font face Gets the familly name of a toy font. Return value: The family name. This string is owned by the font face and remains valid as long as the font face is alive (referenced). Since: 1.8

Toy_Font_Face_Get_Slant 

function Toy_Font_Face_Get_Slant 
(Font_Face: Cairo_Font_Face) return      Cairo_Font_Slant;
Font_Face: A toy font face Gets the slant a toy font. Return value: The slant value Since: 1.8

Toy_Font_Face_Get_Weight 

function Toy_Font_Face_Get_Weight 
(Font_Face: Cairo_Font_Face) return      Cairo_Font_Weight;
Font_Face: A toy font face Gets the weight a toy font. Return value: The weight value Since: 1.8
