嗨我创建了一个PDF文件,其中包含一个图像,我想在创建后打印我的pdf。如果我在内存中使用PDF而不是有文件,然后将其发送给打印机,那么更好......任何想法?如何打印使用iText创建的PDF?
我正在使用iText。检查我的代码:
import com.lowagie.text.Document;
import com.lowagie.text.DocumentException;
import com.lowagie.text.Image;
import com.lowagie.text.PageSize;
import com.lowagie.text.Rectangle;
import com.lowagie.text.pdf.PdfContentByte;
import com.lowagie.text.pdf.PdfPrinterGraphics2D;
import com.lowagie.text.pdf.PdfTemplate;
import com.lowagie.text.pdf.PdfWriter;
import javax.imageio.ImageIO;
import java.awt.Color;
import java.awt.Graphics2D;
import java.awt.Toolkit;
import java.awt.image.BufferedImage;
import java.io.ByteArrayInputStream;
import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.InputStream;
private boolean exportToPdfThroughPNG(String fileName, float width, float height) throws DocumentException, IOException {
logger.debug("[boolean exportToPdfQuick() throws IOException, DocumentException]");
BufferedImage pngFile = createPngFile();
Document document = new Document();
document.setPageSize(new Rectangle(width, height));
PdfWriter.getInstance(document, new FileOutputStream(fileName));
document.open();
Image image = Image.getInstance(Toolkit.getDefaultToolkit().createImage(pngFile.getSource()), Color.WHITE);
document.add(image);
// If some day anyone wants to put text in the pdf. @Eduardo
// document.add(new Paragraph("title of the process"));
document.close();
return true;
}
在此先感谢!
这是在Windows上还是在不同的平台上运行? – 2011-01-06 13:48:27
