IFontProvider

Interface IFontProvider

public interface IFontProvider
Provides font files as streams for AutoFit, PDF export, and image export.

Implement this interface and assign an instance to Workbook.FontProvider. getFontFilePaths() returns the available font file paths or resource names, and those values are passed to getFont(String) to open the corresponding font stream. The returned stream is closed after use.


 IFontProvider currentProvider = Workbook.FontProvider;
 try {
     Workbook.FontProvider = new IFontProvider() {
         public List<String> getFontFilePaths() {
             return Arrays.asList("fonts/BIZ-UDMinchoM.ttc");
         }

         public InputStream getFont(String fontFilePath) {
             return getClass().getClassLoader().getResourceAsStream(fontFilePath);
         }
     };

     Workbook workbook = new Workbook();
     IWorksheet worksheet = workbook.getWorksheets().get(0);

     worksheet.getRange("A1").setValue("あなたは日本語を話せますか？");
     worksheet.getRange("A1").getFont().setName("BIZ UDMincho");
     worksheet.getRange("A:A").autoFit();
 } finally {
     Workbook.FontProvider = currentProvider;
 }
