Method Details

buildDefaultJava2DBasedFontInfo

public static FontInfo buildDefaultJava2DBasedFontInfo(FontInfo fontInfo,
 FOUserAgent userAgent)

Builds a default FontInfo object for use with output formats using the Java2D font setup.

Parameters:

fontInfo - the font info object to populate

userAgent - the user agent

Returns:

the populated font information object

createGlyphVector

public static GlyphVector createGlyphVector(String text,
 Graphics2D g2d,
 Font font,
 FontInfo fontInfo)

Creates an instance of GlyphVector that correctly handle surrogate pairs and advanced font features such as GSUB/GPOS/GDEF.

Parameters:

text - Text to render

g2d - the target Graphics2D instance

font - the font instance

fontInfo - the font information

Returns:

an instance of GlyphVector

createGlyphVector

private static GlyphVector createGlyphVector(String text,
 Graphics2D g2d)

Creates a GlyphVector using characters. Filters out non-bmp characters.

createGlyphVectorMultiByteFont

private static GlyphVector createGlyphVectorMultiByteFont(String text,
 Graphics2D g2d,
 MultiByteFont multiByteFont)

Creates a GlyphVector using glyph indexes instead of characters. To correctly support the advanced font features we have to build the GlyphVector passing the glyph indexes instead of the characters. This because some of the chars in text might have been replaced by an internal font representation during GlyphMapping.processWordMapping. Eg 'fi' replaced with the corresponding character in the font ligatures table (GSUB).

getMultiByteFont

private static MultiByteFont getMultiByteFont(String fontName,
 FontInfo fontInfo)

Returns an instance of MultiByteFont for the given font name. This method will try to unwrap containers such as CustomFontMetricsMapper and LazyFont

Parameters:

fontName - font key

fontInfo - font information

Returns:

An instance of MultiByteFont or null if it
