问题描述
我的Java代码与iText的5.5和xmlworker罐的帮助下写阿拉伯字符，但留下来的 writer.setRunDirection（PdfWriter.RUN_DIRECTION_RTL）使用权后，即使它的写作。
I have java code that writes arabic characters with the help of itext 5.5 and xmlworker jars, but its writing left to right even after writer.setRunDirection(PdfWriter.RUN_DIRECTION_RTL) is used.
使用的代码是：
public class CreateArabic extends DefaultHandler {
/** Paths to and encodings of fonts we're going to use in this example */
public static String[][] FONTS = {
{"C:/arialuni.ttf", BaseFont.IDENTITY_H},
{"C:/abserif4_5.ttf", BaseFont.IDENTITY_H},
{"C:/damase.ttf", BaseFont.IDENTITY_H},
{"C:/fsex2p00_public.ttf", BaseFont.IDENTITY_H}
};
/** Holds he fonts that can be used for the peace message. */
public FontSelector fs;
public CreateArabic() {
fs = new FontSelector();
for (int i = 0; i < FONTS.length; i++) {
fs.addFont(FontFactory.getFont(FONTS[i][0], FONTS[i][1], BaseFont.EMBEDDED));
}
}
public static void main(String args[]) {
try {
// step 1
Rectangle pagesize = new Rectangle(8.5f * 72, 11 * 72);
Document document = new Document();//pagesize, 72, 72, 72, 72);// step1
PdfWriter writer = PdfWriter.getInstance(document,
new FileOutputStream("c:\\report.pdf"));
writer.setInitialLeading(200.5f);
//writer.getAcroForm().setNeedAppearances(true);
//writer.setRunDirection(PdfWriter.RUN_DIRECTION_RTL);
document.open();
FontFactory.registerDirectories();
Font font = FontFactory.getFont("C:\\damase.ttf",
BaseFont.IDENTITY_H, true, 22, Font.BOLD);
// step 3
document.open();
// step 4
XMLWorkerHelper helper = XMLWorkerHelper.getInstance();
// CSS
CSSResolver cssResolver = new StyleAttrCSSResolver();
CssFile cssFile = helper.getCSS(new FileInputStream(
"D:\\Itext_Test\\Test\\src\\test.css"));
cssResolver.addCss(cssFile);
// HTML
XMLWorkerFontProvider fontProvider = new XMLWorkerFontProvider();
// fontProvider.addFontSubstitute("lowagie", "garamond");
CssAppliers cssAppliers = new CssAppliersImpl(fontProvider);
HtmlPipelineContext htmlContext = new HtmlPipelineContext(
cssAppliers);
htmlContext.setTagFactory(Tags.getHtmlTagProcessorFactory());
// // Pipelines
PdfWriterPipeline pdf = new PdfWriterPipeline(document, writer);
HtmlPipeline html = new HtmlPipeline(htmlContext, pdf);
CssResolverPipeline css = new CssResolverPipeline(cssResolver,
html);
writer.setRunDirection(PdfWriter.RUN_DIRECTION_RTL);
System.out.println("RUN DIRECTION --> "+writer.getRunDirection());
XMLWorker worker = new XMLWorker(css, true);
XMLParser p = new XMLParser(worker,Charset.forName("UTF-8"));
String htmlString2 = "<html><body style=\"color:red;\">Hello"+"??"+"</body></html>";
String htmlString = "<body style='font-family:arial;'>h"+"??"+"<p style='font-family:arial;' > ????? </p></body>";
String html1 ="<html><head></head><body>Hello <p style=\"color:red\" >oo ??</p> World! \u062a\u0639\u0637\u064a \u064a\u0648\u0646\u064a\u0643\u0648\u062f \u0631\u0642\u0645\u0627 \u0641\u0631\u064a\u062f\u0627 \u0644\u0643\u0644 \u062d\u0631\u0641 "+htmlString+"Testing</body></html>";
ByteArrayInputStream is = new ByteArrayInputStream(htmlString.getBytes("UTF-8"));
p.detectEncoding(is);
p.parse(is, Charset.forName("UTF-8"));//.parse(is, "UTF-8");//parse(is);//ASMO-708
// step 5
document.close();
} catch (Exception ex) {
ex.printStackTrace();
}
}
}
还附加了输出文件。
推荐答案
如文档所述，这不应该有效：
As documented, this is not supposed to work:
writer.setRunDirection(PdfWriter.RUN_DIRECTION_RTL);
阿拉伯语（和希伯来语）只能在 ColumnText的上下文中正确呈现和 PdfPCell 。换句话说：如果要使用XML Worker中的阿拉伯语，则需要创建 ElementList ，然后将元素添加到 ColumnText 对象已完成。
Arabic (and Hebrew) can only be rendered correctly in the context of ColumnText and PdfPCell. In other words: if you want to use Arabic from XML Worker, you need to create an ElementList and then add the elments to a ColumnText object as is done here.
您需要在 ColumnText 对象的级别设置运行方向。
You need to set the run direction at the level of the ColumnText object.
