IMPORT_C CFbsDrvDevice();

Description

IMPORT_C ~CFbsDrvDevice();

Description

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

Description

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 CFbsDrvDevice::ReleaseFont(CFont *).

This function is replaced by CFbsDrvDevice::GetNearestFontToDesignHeightInTwips(CFont *&,const TFontSpec &)

Parameters

Return value

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

Description

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 CFbsDrvDevice::ReleaseFont(CFont *).

This function replaces CFbsDrvDevice::GetNearestFontInTwips(CFont *&,const TFontSpec &)

Parameters

Return value

IMPORT_C virtual void ReleaseFont(CFont *aFont);

Description

Releases the specified font.

It is used to indicate that the specified font is no longer needed for use by the device map. As fonts can be shared between applications, this function does not delete the copy of the font from RAM unless the font was only being used by this particular device map.

An implementation is supplied by a derived class.

Parameters

IMPORT_C virtual TInt NumTypefaces() const;

Description

Gets the number of typefaces supported by the graphics device.

Return value

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

Description

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

Parameters

See also:

• CFbsDrvDevice::NumTypefaces()constGets the number of typefaces supported by the graphics device.

IMPORT_C virtual TInt FontHeightInTwips(TInt aTypefaceIndex, TInt aHeightIndex) const;

Description

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

Return value

IMPORT_C virtual TInt CreateContext(CGraphicsContext *&aGc);

Description

Creates a graphics context for the device.

Parameters

Return value

IMPORT_C virtual void CreateControlL(CPrinterPort *aPrinterPort);

Description

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

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

Description

Parameters

Return value

• CFbsDrvDevice::SetModelL(const TPrinterModelHeader &,CStreamStore &)

IMPORT_C virtual TSize KPixelSizeInTwips() const;

Description

Return value
