Detailed Description

helper class for reading a binary unicode font (DBUF)

Constructor & Destructor Documentation

GlsUnicodeFontDBUFReader	(	const unsigned char *const *	inlineDBUFData,
		const unsigned int	lineLength,
		const unsigned int	totalInlineSize,
		const bool	isCompressed,
		unsigned long	uncompressedSize
	)

ctor – construct from inline data (optionally compressed)

Parameters

inlineDBUFData	inline DBUF data to read
lineLength	length of lines in inline data
totalInlineSize	total number of bytes (not including NULL terminators) of inline data
isCompressed	true if dbuf data is zlib compressed else false
uncompressedSize	uncompressed size of data if isCompressed else ignored

GlsUnicodeFontDBUFReader	(	const unsigned char *const	dbufData,
		const unsigned int	dbufDataLength
	)

ctor – construct from noninline data (not compressed)

Parameters

dbufData	DBUF data to read
dbufDataLength	number of bytes of data in dbufData

Member Function Documentation

std::string GetErrorMsg

(

void

)

const

Get an error message if !IsValid()

Returns

an error message if !IsValid()

GlsFontBase::AttrCont_t GetGlsFontBaseCharAttributes

(

void

)

Get the GlsFontBase::AttrCont_t associated with the unicode font

Returns

the GlsFontBase::AttrCont_t associated with the unicode font

GlsFontBase::FontAttr_t GetGlsFontBaseFontAttributes

(

void

)

Get the GlsFontBase::FontAttr_t associated with the unicode font

Returns

the GlsFontBase::FontAttr_t associated with the unicode font

Image* GetGlsFontBaseTexture

(

void

)

Get the first image associated with the unicode font (suitable for use by GlsFontBase)

Returns

the first image associated with the unicode font (suitable for use by GlsFontBase)

Note

will increase usage count on texture by one so caller should call DeleteUsage when texture is no longer needed

GlsUnicodeFontBase::AttrContUnicode_t GetGlsUnicodeFontBaseCharAttributes

(

void

)

Get the GlsUnicodeFontBase::AttrContUnicode_t associated with the unicode font

Returns

the GlsFontBase::AttrContUnicode_t associated with the unicode font

GlsUnicodeFontBase::FontAttrUnicode_t GetGlsUnicodeFontBaseFontAttributes

(

void

)

Get the GlsUnicodeFontBase::FontAttrUnicode_t associated with the unicode font

Returns

the GlsFontBase::FontAttrUnicode_t associated with the unicode font

std::vector<Image*> GetGlsUnicodeFontBaseTextures

(

void

)

Get the textures associated with the unicode font

Returns

the textures associated with the unicode font

Note

each texture will have its usage count increased by one so caller should call DeleteUsage on each texture when they are no longer needed

void InitializeFromDBUF ( const unsigned char *const  dbufData, const unsigned int  dbufDataLength  )

protected

initialize the reader from the given DBUF data

Parameters

dbufData	DBUF data to read
dbufDataLength	number of bytes of data in dbufData

bool IsValid

(

void

)

const

Determine if a valid DBUF was read

Returns

true if a valid DBUF was read else false

Member Data Documentation

GlsUnicodeFontBase::FontAttrUnicode_t _fontAttrUnicode

protected

unicode font attributes read from DBUF data

std::vector<Image*> _fontTextures

protected

font textures read from DBUF data

bool _isValid

protected

true if a valid DBUF was read else false
