Method Details

getSeenFiles

protected HashMap<String,FontFileRecord> getSeenFiles()

getFileFilter

protected abstract FileFilter getFileFilter()

initialize

public void initialize()

Specified by:

initialize in interface FontRegistry

getDefaultEncoding

protected String getDefaultEncoding()

registerDefaultFontPath

public void registerDefaultFontPath()

Register os-specific font paths to the PDF-FontFactory. For unix-like operating systems, X11 is searched in /usr/X11R6 and the default truetype fontpath is added. For windows the system font path is added (%windir%/fonts)

registerPrimaryName

protected void registerPrimaryName(String name,
 DefaultFontFamily family)

registerAlternativeName

protected void registerAlternativeName(String name,
 DefaultFontFamily family)

registerFullName

protected void registerFullName(String name,
 DefaultFontFamily family)

createFamily

protected DefaultFontFamily createFamily(String name)

getRegisteredFamilies

public String[] getRegisteredFamilies()

Specified by:

getRegisteredFamilies in interface FontRegistry

getAllRegisteredFamilies

public String[] getAllRegisteredFamilies()

Specified by:

getAllRegisteredFamilies in interface FontRegistry

getFontFamily

public FontFamily getFontFamily(String name)

Description copied from interface: FontRegistry

Tries to find a font family with the given name, looking through all alternative font names if neccessary.

Specified by:

getFontFamily in interface FontRegistry

Returns:

the font family or null, if there is no such family.

loadFromCache

protected void loadFromCache(String encoding)

populateFromCache

protected void populateFromCache(HashMap<String,DefaultFontFamily> cachedFontFamilies,
 HashMap<String,DefaultFontFamily> cachedFullFontNames,
 HashMap<String,DefaultFontFamily> cachedAlternateNames)

loadFromCache

protected void loadFromCache(String encoding,
 String filename)

getCacheFileName

protected String getCacheFileName()

storeToCache

protected void storeToCache(String encoding)

registerFontPath

public void registerFontPath(File file,
 String encoding)

Register all fonts (*.ttf files) in the given path.

Parameters:

file - the directory that contains the font files.

encoding - the encoding for the given font.

isCached

protected boolean isCached(File file)

registerFontFile

public void registerFontFile(String filename,
 String encoding)

Register the font (must end this *.ttf) to the FontFactory.

Parameters:

filename - the filename.

encoding - the encoding.

registerFontFile

public void registerFontFile(File file,
 String encoding)

addFont

protected abstract boolean addFont(File font,
 String encoding)
                            throws IOException

Adds the fontname by creating the basefont object. This method tries to load the fonts as embeddable fonts, if this fails, it repeats the loading with the embedded-flag set to false.

Parameters:

font - the font file name.

encoding - the encoding.

Returns:

true, if registration was successful, false otherwise.

Throws:

IOException - if the base font file could not be read.

safeSystemGetProperty

protected String safeSystemGetProperty(String name,
 String defaultValue)

isCacheValid

protected boolean isCacheValid(HashMap cachedSeenFiles)

createStorageLocation

protected File createStorageLocation()
