嗨我創建了一個PDF文件,其中包含一個圖像,我想在創建後打印我的pdf。如果我在內存中使用PDF而不是有文件,然後將其發送給打印機,那麼更好......任何想法?如何打印使用iText創建的PDF?
我正在使用iText。檢查我的代碼:
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;
}
在此先感謝!
這是在Windows上還是在不同的平臺上運行? – 2011-01-06 13:48:27
