Parameters:

Parameter	Type	Description
priority	int	Font source priority. See the FontSourceBase.getPriority() property description for more information.

getAvailableFonts()

public ArrayList getAvailableFonts()

Returns list of fonts available via this source.

Examples:

Shows how to list available fonts.


 // Configure Aspose.Words to source fonts from a custom folder, and then print every available font.
 FontSourceBase[] folderFontSource = {new FolderFontSource(getFontsDir(), true)};

 for (PhysicalFontInfo fontInfo : folderFontSource[0].getAvailableFonts()) {
     System.out.println(MessageFormat.format("FontFamilyName : {0}", fontInfo.getFontFamilyName()));
     System.out.println(MessageFormat.format("FullFontName  : {0}", fontInfo.getFullFontName()));
     System.out.println(MessageFormat.format("Version  : {0}", fontInfo.getVersion()));
     System.out.println(MessageFormat.format("FilePath : {0}\n", fontInfo.getFilePath()));
 }

Returns: java.util.ArrayList

getFontDataInternal()

public Iterable getFontDataInternal()

Returns: java.lang.Iterable

getPriority()

public int getPriority()

Returns the font source priority.

Remarks:

This value is used when there are fonts with the same family name and style in different font sources. In this case Aspose.Words selects the font from the source with the higher priority value.

The default value is 0.

Examples:

Shows how to use a font file in the local file system as a font source.


 FileFontSource fileFontSource = new FileFontSource(getMyDir() + "Alte DIN 1451 Mittelschrift.ttf", 0);

 Document doc = new Document();
 doc.setFontSettings(new FontSettings());
 doc.getFontSettings().setFontsSources(new FontSourceBase[]{fileFontSource});

 Assert.assertEquals(getMyDir() + "Alte DIN 1451 Mittelschrift.ttf", fileFontSource.getFilePath());
 Assert.assertEquals(FontSourceType.FONT_FILE, fileFontSource.getType());
 Assert.assertEquals(0, fileFontSource.getPriority());

Returns: int - The font source priority.

getPriorityInternal()

public int getPriorityInternal()

Returns: int

getSystemFontFolders()

public static String[] getSystemFontFolders()

Returns system font folders or empty array if folders are not accessible.

Remarks:

On some platforms Aspose.Words could search system fonts not only through folders but in other sources too. For example, on Windows platform Aspose.Words search fonts also in the registry.

Examples:

Shows how to access a document’s system font source and set font substitutes.
