Member Functions Documentation

CreateContext(CGraphicsContext *&)

IMPORT_C TInt

CreateContext

(

CGraphicsContext *&

aGC

)

[virtual]

Creates a graphics context for the device.

Parameters

CGraphicsContext *& aGC

On return, contains a pointer to the created graphics context.

CreateControlL(CPrinterPort *)

IMPORT_C void

CreateControlL

(

CPrinterPort *

aPrinterPort

)

[virtual]

Creates a printer control.

The printer control is an instance of a CPrinterControl derived class; it is assigned to this printer device's iControl member.

Note that this function is called by CPrintSetup::StartPrintL().

Parameters

CPrinterPort * aPrinterPort

Pointer to an instance of a printer port.

FontHeightInTwips(TInt, TInt)

IMPORT_C TInt	FontHeightInTwips	(	TInt	aTypefaceIndex,
			TInt	aHeightIndex
		)	const [virtual]

Get the height of a font in twips.

The font is identified by typeface and height.

The value returned is rounded up or down to the nearest font height in twips.

Parameters

TInt aTypefaceIndex	An index identifying the typeface, in the range: 0 to (NumTypefaces() - 1).
TInt aHeightIndex	An index identifying the font height, in the range: 0 to (iNumHeights - 1). Note that iNumHeights is in the TTypefaceSupport object returned by TypefaceSupport().

GetNearestFontInTwips(CFont *&, const TFontSpec &)

IMPORT_C TInt	GetNearestFontInTwips	(	CFont *&	aFont,
			const TFontSpec &	aFontSpec
		)

Creates a font from those available in the printer device's typeface store that most closely matches a font specification.

When the font is no longer needed, call ReleaseFont() .

This function is replaced by GetNearestFontToDesignHeightInTwips()

Parameters

CFont *& aFont	On return, points to the font which most closely matches the specified font.
const TFontSpec & aFontSpec	An absolute font specification. Its iHeight member is interpreted as being in twips.

GetNearestFontToDesignHeightInTwips(CFont *&, const TFontSpec &)

IMPORT_C TInt	GetNearestFontToDesignHeightInTwips	(	CFont *&	aFont,
			const TFontSpec &	aFontSpec
		)

Creates a font from those available in the printer device's typeface store that most closely matches a font specification.

When the font is no longer needed, call ReleaseFont() .

This function replaces GetNearestFontInTwips()

Parameters

CFont *& aFont	On return, points to the font which most closely matches the specified font.
const TFontSpec & aFontSpec	An absolute font specification. Its iHeight member is interpreted as being in twips.

SetModel(const TPrinterModelHeader &, CStreamStore &)

IMPORT_C TInt	SetModel	(	const TPrinterModelHeader &	aModel,
			CStreamStore &	aStore
		)	[virtual]

Interface is deprecated because it is unsafe as it may leave. It is available for backward compatibility reasons only. CFbsDrvDevice::SetModelL

Parameters

const TPrinterModelHeader & aModel
CStreamStore & aStore

SetModelL(const TPrinterModelHeader &, CStreamStore &)

IMPORT_C TInt	SetModelL	(	const TPrinterModelHeader &	aModel,
			CStreamStore &	aStore
		)

Parameters

const TPrinterModelHeader & aModel
CStreamStore & aStore

TypefaceSupport(TTypefaceSupport &, TInt)

IMPORT_C void	TypefaceSupport	(	TTypefaceSupport &	aTypefaceSupport,
			TInt	aTypefaceIndex
		)	const [virtual]

Gets typeface information for a specified typeface.

This information is returned in aTypefaceSupport, and includes:

the typeface name and typeface attributes

the number of font heights

the maximum and minimum font heights

whether it is a scalable typeface

NumTypefaces()

Parameters

TTypefaceSupport & aTypefaceSupport	On return, contains the typeface information.
TInt aTypefaceIndex	A typeface index number, in the range: zero to (NumTypefaces() - 1).
