Definition at line 94 of file truetype_font_dev.h.

Constructor & Destructor Documentation

pp::TrueTypeFont_Dev::TrueTypeFont_Dev ( )

Default constructor for creating a TrueTypeFont_Dev object.

pp::TrueTypeFont_Dev::TrueTypeFont_Dev	(	const InstanceHandle &	instance,
		const TrueTypeFontDesc_Dev &	desc
	)

A constructor used to create a TrueTypeFont_Dev and associate it with the provided Instance.

Parameters

[in] instance The instance that owns this resource.

pp::TrueTypeFont_Dev::TrueTypeFont_Dev ( const TrueTypeFont_Dev & other )

The copy constructor for TrueTypeFont_Dev.

Parameters

[in] other A reference to a TrueTypeFont_Dev.

pp::TrueTypeFont_Dev::TrueTypeFont_Dev	(	PassRef	,
		PP_Resource	resource
	)

A constructor used when you have received a PP_Resource as a return value that has had its reference count incremented for you.

Parameters

[in] resource A PP_Resource corresponding to a TrueType font.

Member Function Documentation

int32_t pp::TrueTypeFont_Dev::Describe ( const CompletionCallbackWithOutput< TrueTypeFontDesc_Dev > & callback )

Returns a description of the given font resource. This description may differ from the description passed to Create, reflecting the host's font matching and fallback algorithm.

Parameters

[in] callback A CompletionCallback to be called upon completion of Describe.

Returns: A return code from pp_errors.h. If an error code is returned, the descriptor will be left unchanged.

static int32_t pp::TrueTypeFont_Dev::GetFontFamilies	(	const InstanceHandle &	instance,
		const CompletionCallbackWithOutput< std::vector< Var > > &	callback
	)

static

Gets an array of TrueType font family names available on the host. These names can be used to create a font from a specific family.

Parameters

[in]	instance	A `InstanceHandle` requesting the family names.
[in]	callback	A `CompletionCallbackWithOutput` to be called upon completion of GetFontFamilies.

Returns: If >= 0, the number of family names returned, otherwise an error code from pp_errors.h.

static int32_t pp::TrueTypeFont_Dev::GetFontsInFamily	(	const InstanceHandle &	instance,
		const Var &	family,
		const CompletionCallbackWithOutput< std::vector< TrueTypeFontDesc_Dev > > &	callback
	)

static

Gets an array of TrueType font descriptors for a given font family. These descriptors can be used to create a font in that family and matching the descriptor attributes.

Parameters

[in]	instance	A `PP_Instance` requesting the font descriptors.
[in]	family	A `Var` holding a string specifying the font family.
[in]	callback	A `CompletionCallbackWithOutput` to be called upon completion of GetFontsInFamily.

Returns: If >= 0, the number of font descriptors returned, otherwise an error code from pp_errors.h.

int32_t pp::TrueTypeFont_Dev::GetTable	(	uint32_t	table,
		int32_t	offset,
		int32_t	max_data_length,
		const CompletionCallbackWithOutput< std::vector< char > > &	callback
	)

Copies the given font table into client memory.

Parameters

[in]	table	A 4 byte value indicating which table to copy. For example, 'glyf' will cause the outline table to be copied into the output array. A zero tag value will cause the entire font to be copied.
[in]	offset	The offset into the font table.
[in]	max_data_length	The maximum number of bytes to transfer from `offset`.
[in]	callback	A `CompletionCallbackWithOutput` to be called upon completion of GetTable.

Returns: If >= 0, the table size in bytes, otherwise an error code from pp_errors.h.

int32_t pp::TrueTypeFont_Dev::GetTableTags ( const CompletionCallbackWithOutput< std::vector< uint32_t > > & callback )

Gets an array of identifying tags for each table in the font. These tags can be used to request specific tables using GetTable.

Parameters

[in] callback A CompletionCallbackWithOutput to be called upon completion of GetTableTags.

Returns: If >= 0, the number of table tags returned, otherwise an error code from pp_errors.h.
