Мы используем нашу собственную PrintFontProvider
.Это должно помочь вам:
private static final CSSResolver cssResolver = XMLWorkerHelper.getInstance().getDefaultCssResolver(true);
private static final HtmlPipelineContext htmlContext = new HtmlPipelineContext(null);
static {
htmlContext.setTagFactory(Tags.getHtmlTagProcessorFactory());
htmlContext.autoBookmark(false);
// Our own PrintFontProvider provides Fonts as needed...
htmlContext.setCssAppliers(new CssAppliersImpl(new PrintFontProvider()));
// We apply some default styles to the pdf generation...
try {
String styling = "* { font-size: 8pt; line-height: 1.3em; }\n";
styling += "* * { font-size: inherit; }\n";
styling += "p { margin: 5px 2.5pt; }\n";
styling += "ul, ol { margin: 2px 0; }\n";
cssResolver.clear();
cssResolver.addCss(styling, true);
}
catch (CssResolverException ex) {
// Handle errors as needed...
}
}
Вот наша реализация:
public class PrintFontProvider extends FontFactoryImp {
public static final String DEFAULT_FONT = "LiberationSans";
@Override
public Font getFont(String fontName, String encoding, boolean embedded, float size, int style, BaseColor color, boolean cached) {
LogUtils.debug(PrintFontProvider.class, "in getFont with fontName = '" + fontName + "'");
// ZapfDingbats ist ein Sonderfall... die wollen wir auch liefern!
if ("ZapfDingbats".equals(fontName)) {
return new Font(this.load("fonts/ZapfDingbats/zapf-dingbats-bt.ttf"), size, style, color);
}
// LiberationSans – http://de.wikipedia.org/wiki/Liberation_(Schriftart) – http://scripts.sil.org/cms/scripts/page.php?item_id=OFL_web
if (style == Font.NORMAL) return new Font(this.load("fonts/Liberation/LiberationSans-Regular.ttf"), size, Font.NORMAL, color);
if (style == Font.BOLD) return new Font(this.load("fonts/Liberation/LiberationSans-Bold.ttf"), size, Font.NORMAL, color);
if (style == Font.BOLDITALIC) return new Font(this.load("fonts/Liberation/LiberationSans-BoldItalic.ttf"), size, Font.NORMAL, color);
if (style == Font.ITALIC) return new Font(this.load("fonts/Liberation/LiberationSans-Italic.ttf"), size, Font.NORMAL, color);
return new Font(this.load("fonts/Liberation/LiberationSans-Regular.ttf"), size, style, color);
}
private BaseFont load(String path) {
LogUtils.debug(PrintFontProvider.class, "path = {0}", path);
try {
URL fontResource = PrintSettings.class.getResource(path);
if (fontResource == null) {
LogUtils.warn(PrintFontProvider.class, "Kann Font {0} nicht finden... liefere null!", path);
return null;
}
String fontPath = fontResource.toExternalForm();
if (fontPath.startsWith("vfs:")) fontPath = fontPath.substring(4);
if (fontPath.startsWith("/content/")) fontPath = fontPath.substring(fontPath.indexOf("/our/package"));
BaseFont baseFont = BaseFont.createFont(fontPath, BaseFont.IDENTITY_H, BaseFont.EMBEDDED);
baseFont.setSubset(true); // Nur die benutzen Chars einbetten!
return baseFont;
}
catch (DocumentException ex) {
LogUtils.warn(PrintFontProvider.class, "Kann Font {0} nicht erzeugen... liefere DEFAULT_FONT!", path);
}
catch (IOException ex) {
LogUtils.warn(PrintFontProvider.class, "Kann Font {0} nicht erzeugen... liefere DEFAULT_FONT!", path);
}
return FontFactory.getFont(DEFAULT_FONT, "UTF-8", true, 8f, Font.NORMAL, PrintSettings.COLOR_TEXT).getBaseFont();
}
private static boolean notInitialized = true;
public static void initFactory() {
if (notInitialized) {
FontFactory.defaultEmbedding = true;
FontFactory.setFontImp(new PrintFontProvider());
notInitialized = false;
}
}
}
Вы должны позвонить PrintFontProvider.initFactory()
, чтобы сделать его по умолчанию.
