Field Details

instanceHash

private final HashMap<String,Font> instanceHash

Map of concrete instances of fonts including size, weight, etc.

availableFontsHash

private final HashMap<String,Font> availableFontsHash

 String fontFamilyNameOverride,
 Integer fontWeightOverride,
 IdentValue fontStyleOverride)

addFontFaceFont

private void addFontFaceFont(String fontFamilyNameOverride,
 IdentValue fontWeightOverride,
 IdentValue fontStyleOverride,
 String uri)

addFontFile

public void addFontFile(File fontFile,
 String fontFamilyNameOverride,

getFontFamily

private FontFamily<Java2DFontResolver.FontDescription> getFontFamily(String fontFamilyName)

normalizeFontFamily

private String normalizeFontFamily(String fontFamily)

resolveFontFaceBaseFont

private Font resolveFontFaceBaseFont(String normalizedFontFamily,

resolveFont

public FSFont resolveFont(SharedContext ctx,
 String[] families,
 float size,
 IdentValue weight,

 float size,
 IdentValue weight,
 IdentValue style,
 IdentValue variant)

Creates a concrete instance of a font at specified size, weight, style and variant.

getFontInstanceHashName

protected static String getFontInstanceHashName(SharedContext ctx,
 String name,
 float size,
 IdentValue weight,
 IdentValue style,
 IdentValue variant)

Gets the hash key for a concrete instance of a font. This incorporates size, weight, etc.
