Member Function Documentation

const TTypefaceAttrib& CartoType::CTypeface::Attrib

(

)

const [inline]

Return the attributes (name, etc.) of this typeface.

virtual void CartoType::CTypeface::ClearCachedData

(

)

[pure virtual]

Clear any cached data.

virtual void* CartoType::CTypeface::FreeTypeFace

(

)

[inline, virtual]

Return the FreeType FT_Face if any. Used only in supporting tools, not in the main CartoType library.

virtual CGlyph* CartoType::CTypeface::Glyph	(	TResult &	aError,
		int32	aCode
	)		[pure virtual]

Create a glyph for the character code or glyph code aCode. Character codes are Unicode values. Glyph codes are negative numbers.

virtual bool CartoType::CTypeface::HasCharacter

(

int32

aCode

)

[pure virtual]

Return true if this typeface supports (contains a glyph or glyphs for) the character indexed by the Unicode value aCode.

int32 CartoType::CTypeface::Id

(

)

const [inline]

Return the unique ID.

const TTypefaceInstance& CartoType::CTypeface::Instance

(

)

const [inline]

Return the instance (size, etc.) currently set for this typeface.

virtual int32 CartoType::CTypeface::MemoryUsed

(

)

[pure virtual]

Return the number of bytes of heap used by the typeface.

const TFontMetrics& CartoType::CTypeface::Metrics

(

)

const [inline]

Return the metrics of the current instance.

virtual TResult CartoType::CTypeface::OnNewInstance

(

)

[pure virtual]

Set up the typeface so that it can create glyphs for a new instance. This function is called immediately after iInstance is changed. It must set iMetrics.

CT_EXPORT uint32 CTypeface::Script

(

uint32

aCode

)

[static]

Return the script of a character.

void CartoType::CTypeface::SetId

(

int32

aId

)

[inline]

Set the unique ID. For use by CTypefaceResource.

CT_EXPORT void CTypeface::SetScripts

(

)

Set the record of which scripts are supported.
