Constructor Detail

SVGFontFamily

public SVGFontFamily(GVTFontFace fontFace,
                     Element fontElement,
                     BridgeContext ctx)

Constructs an SVGFontFamily.

Parameters:

fontFace - The font face object that describes this font family.

fontElement - The element that contains the font data for this family.

ctx - The bridge context. This is required for lazily loading the font data at render time.

Method Detail

getFamilyName

public java.lang.String getFamilyName()

Returns the family name of this font.

Specified by:

getFamilyName in interface GVTFontFamily

Returns:

The font family name.

getFontFace

public GVTFontFace getFontFace()

Returns the font-face associated with this font family.

Specified by:

getFontFace in interface GVTFontFamily

Returns:

The font face.

deriveFont

public GVTFont deriveFont(float size,
                          java.text.AttributedCharacterIterator aci)

Derives a GVTFont object of the correct size.

Specified by:

deriveFont in interface GVTFontFamily

Parameters:

size - The required size of the derived font.

aci - The character iterator containing the text to be rendered using the derived font.

Returns:

The derived font.

deriveFont

public GVTFont deriveFont(float size,
                          java.util.Map attrs)

Derives a GVTFont object of the correct size from an attribute Map.

Specified by:

deriveFont in interface GVTFontFamily

Parameters:

size - The required size of the derived font.

attrs - The Attribute Map to get Values from.

isComplex

public boolean isComplex()

This method looks at the SVG font and checks if any of the glyphs use renderable child elements. If so this is a complex font in that full CSS inheritance needs to be applied. Otherwise if it only uses the 'd' attribute it does not need CSS treatment.

Specified by:

isComplex in interface GVTFontFamily

isComplex

public static boolean isComplex(Element fontElement,
                                BridgeContext ctx)
