1. 创建简单的 PDF 文件
Paket Console.pdf; import java.io.filenotfoundException; import java.io.fileoutputStream; import com.itextpdf.text.document; impor com.itextpdf.text.documentException; .text.paragraph; import com.itextpdf.text.pdf.pdfwriter;/** * 使用 itext 生成 pdf 文件 */kelas publik createPdf {public static Main (string [] args) {createPdf p001 = createPdf baru (); String filename = "p001.pdf"; p001.createPdf (nama file); } public void createPdf (string fileName) {// Langkah 1 dokumen = dokumen baru (pagesize.a4); // Langkah 2 coba {PDFWriter.GetInstance (dokumen, FileOutputStream baru (nama file)); document.addtitle ("id.net"); document.addauthor ("dotuian"); document.addsubject ("Ini adalah subjek file PDF."); document.addkeywords ("Ini adalah kata kunci dari file PDF."); // langkah 3 document.open (); // langkah 4 document.add (paragraf baru ("halo dunia!")); } catch (FileNotFoundException e) {e.printstacktrace (); } catch (DocumentException e) {E.PrintStackTrace (); } akhirnya {// langkah 5 document.close (); }}}
2. 在 PDF 文件中添加 Tabel

3. 在 PDF 文件中添加图片 ， 并且指定文本位置
Paket Console.pdf; import java.io.filenotfoundException; import java.io.fileoutputStream; import com.itextpdf.text.document; impor com.itextpdf.text.documentException; impor com.itextpdf.text .text.pagesize; import com.itextpdf.text.pdf.basefont; import com.itextpdf.text.pdf.pdfcontentByte;文件中添加背景图片 ， 并指定文本在 pdf 文件中的位置 */kelas publik latar belakangImageofpdf {public static void main (string [] args) {latar belakangImageOfpdf p001 = new BackgroundImageOfPdf (); String filename = "p003.pdf"; p001.createPdf (nama file); } public void createPdf (string fileName) {// Langkah 1 Dokumen = dokumen baru (pagesize.a4.rotate (), 0,0,0,0); // Langkah 2 Coba {PDFWrITER PDFWRITER = PDFWRITER.GetInstance (Dokumen, FileOutputStream baru (fileName)); document.addtitle ("id.net"); document.addauthor ("dotuian"); document.addsubject ("Ini adalah subjek file PDF."); document.addkeywords ("Ini adalah kata kunci dari file PDF."); // langkah 3 document.open (); // Langkah 4 Image Image = Image.getInstance ("bg.jpg"); document.add (gambar); PDFContentByte PDFContentByte = PDFWriter.GetDirectContent (); pdfcontentByte.begintext (); Basefont BF = Basefont.CreateFont (Basefont.Times_Roman, Basefont.Winansi, Basefont.EMbedded); pdfcontentByte.setfontandsize (bf, 12); untuk (int i = 0; i <= 842; i = i + 50) {for (int j = 0; j <= 595; j = j + 20) {PdfContentByte.setTextMatrix (i, j); pdfcontentByte.showText ("(" + i + ":" + j + ")"); }} PDFContentByTe.endText (); } catch (FileNotFoundException e) {e.printstacktrace (); } catch (DocumentException e) {E.PrintStackTrace (); } catch (Exception e) {E.PrintStackTrace (); } akhirnya {// langkah 5 document.close (); }}}
