CFontStore Class Reference

class CFontStore : public CTypefaceStore

A store for fonts.

Stores and handles both open and fixed-size fonts. Open fonts are made from open (scalable) typefaces by Open Font plug-in rasterizers. Fonts of other typefaces are stored in a limited number of fixed sizes. However, which is being used is transparent to the user of this class. For example the GetNearestFont...() functions get a bitmap font which may be retrieved from memory or generated via a rasterizer.

GetNearestFontInTwips(CFont *&, const TFontSpec &)

IMPORT_C TIntGetNearestFontInTwips(CFont *&aFont,
const TFontSpec &aFontSpec
)[virtual]

Gets the font which is the nearest to the given font specification.

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

Note that this deprecated function is replaced by the new GetNearestFontToDesignHeightInTwips() yielding (virtually) the same result. However clients are strongly encouraged to use the new GetNearestFontToMaxHeightInTwips() function instead. This will guarantee that every character within any given text string will fit within the given amount of twips, whereas the design height is an aesthetic unit decided by the font designer without strict physical meaning, which may result in cropped characters.

Use GetNearestFontToDesignHeightInTwips

Parameters

CFont *& aFontOn return, contains a pointer to the nearest font.
const TFontSpec & aFontSpecThe specification of the font to be matched.

GetNearestFontInTwips(CFont *&, const TOpenFontSpec &)

GetNearestFontToDesignHeightInTwips(CFont *&, const TFontSpec &)

IMPORT_C TIntGetNearestFontToDesignHeightInTwips(CFont *&aFont,
const TFontSpec &aFontSpec
)[virtual]

Gets the font which is the nearest to the given font specification.

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

const TFontSpec & aFontSpecThe specification of the font to be matched.

GetNearestFontToMaxHeightInTwips(CFont *&, const TFontSpec &, TInt)

IMPORT_C TIntGetNearestFontToMaxHeightInTwips(CFont *&aFont,
const TFontSpec &aFontSpec,
TIntaMaxHeight
)[virtual]

Gets the font which is the nearest to the given font specification.

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

The font and bitmap server returns a pointer to the nearest matching font from those available. Matches to max height of font - this does its best to return a font that will fit within the maximum height specified (but note that variations due to hinting algorithms may rarely result in this height being exceeded by up to one pixel). Problems can also be encountered with bitmap fonts where the typeface exists but doesn't have a font small enough.

Parameters

CFont *& aFontOn return, contains a pointer to the nearest font.
const TFontSpec & aFontSpecThe specification of the font to be matched.
TInt aMaxHeightThe maximum height within which the font must fit.
