FontSourceBase

Inheritance: java.lang.Object

public abstract class FontSourceBase

This is an abstract base class for the classes that allow the user to specify various font sources.

To learn more, visit the Working with Fonts documentation article.

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());
 

Methods

Method	Description
getAvailableFonts()	Returns list of fonts available via this source.
getFontDataInternal()
getPriority()	Returns the font source priority.
getPriorityInternal()
getType()	Returns the type of the font source.
getWarningCallback()	Called during processing of font source when an issue is detected that might result in formatting fidelity loss.
setWarningCallback(IWarningCallback value)	Called during processing of font source when an issue is detected that might result in formatting fidelity loss.

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

getType()

public abstract int getType()

Returns the type of the font source.

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 type of the font source. The returned value is one of FontSourceType constants.

getWarningCallback()

public IWarningCallback getWarningCallback()

Called during processing of font source when an issue is detected that might result in formatting fidelity loss.

Examples:

Shows how to call warning callback when the font sources working with.

 public void fontSourceWarning()
 {
     FontSettings settings = new FontSettings();
     settings.setFontsFolder("bad folder?", false);

     FontSourceBase source = settings.getFontsSources()[0];
     FontSourceWarningCollector callback = new FontSourceWarningCollector();
     source.setWarningCallback(callback);

     // Get the list of fonts to call warning callback.
     ArrayList fontInfos = source.getAvailableFonts();

     Assert.assertEquals("Error loading font from the folder \"bad folder?\": ",
         callback.FontSubstitutionWarnings.get(0).getDescription());
 }

 private static class FontSourceWarningCollector implements IWarningCallback
 {
     /// 
     /// Called every time a warning occurs during processing of font source.
     /// 
     public void warning(WarningInfo info)
     {
         FontSubstitutionWarnings.warning(info);
     }

     public WarningInfoCollection FontSubstitutionWarnings = new WarningInfoCollection();
 }
 

Returns: IWarningCallback - The corresponding IWarningCallback value.

setWarningCallback(IWarningCallback value)

public void setWarningCallback(IWarningCallback value)

Called during processing of font source when an issue is detected that might result in formatting fidelity loss.

Examples:

Shows how to call warning callback when the font sources working with.

 public void fontSourceWarning()
 {
     FontSettings settings = new FontSettings();
     settings.setFontsFolder("bad folder?", false);

     FontSourceBase source = settings.getFontsSources()[0];
     FontSourceWarningCollector callback = new FontSourceWarningCollector();
     source.setWarningCallback(callback);

     // Get the list of fonts to call warning callback.
     ArrayList fontInfos = source.getAvailableFonts();

     Assert.assertEquals("Error loading font from the folder \"bad folder?\": ",
         callback.FontSubstitutionWarnings.get(0).getDescription());
 }

 private static class FontSourceWarningCollector implements IWarningCallback
 {
     /// 
     /// Called every time a warning occurs during processing of font source.
     /// 
     public void warning(WarningInfo info)
     {
         FontSubstitutionWarnings.warning(info);
     }

     public WarningInfoCollection FontSubstitutionWarnings = new WarningInfoCollection();
 }
 

Parameters:

Parameter	Type	Description
value	IWarningCallback	The corresponding IWarningCallback value.
