How to add an image over a table with Itext?
I'm using the version 5.5.10
implementation 'com.itextpdf:itextg:5.5.10'
Edit: The image can not be inside the row / column, it must be independent to populate any position on the screen
I'm trying to add an image over the columns of a table, but the result is this:
It always lies below the rows of the column.
To add the image I'm doing so:
public void addImg (int dwb, float x, float y, float desc) {
try{
Bitmap bitmap = dwbToBitmap(context, dwb);
ByteArrayOutputStream stream3 = new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.PNG, 100, stream3);
Image image = Image.getInstance(stream3.toByteArray());
stream3.close();
image.scaleToFit(sizeImgFit, sizeImgFit);
image.setAbsolutePosition(35.6f + 10f + x, height-y-sizeImg-(height-desc));
document.add(image);
}catch (Exception e){
log("addImg", e);
}
}
I have already tried to change the order, create the first table and then add the images or vise versa, but it does not work.
Does anyone know how to put the images in position Z above all?
I create the table like this:
public void createTable(ArrayList<String> header, ArrayList<String[]> clients){
float height = 569/header.size();
sizeImg = height;
sizeImgFit = sizeImg - 2;
PdfPTable pdfPTable = new PdfPTable(header.size());
pdfPTable.setWidthPercentage(100);
PdfPCell pdfPCell;
int indexC = 0;
while(indexC < header.size()){
pdfPCell = new PdfPCell(new Phrase(header.get(indexC++), fHeaderText));
pdfPCell.setHorizontalAlignment(Element.ALIGN_CENTER);
pdfPCell.setBackgroundColor(BaseColor.GRAY);
pdfPTable.addCell(pdfPCell);
}
int i = 0;
for(String[] row : clients){
int p = 0;
for(String linha : row){
pdfPCell = new PdfPCell(new Phrase(linha, fText));
pdfPCell.setHorizontalAlignment(Element.ALIGN_CENTER);
pdfPCell.setVerticalAlignment(Element.ALIGN_CENTER);
pdfPCell.setFixedHeight(height);
pdfPTable.addCell(pdfPCell);
log("linha - coluna", i + " - " + p);
p++;
}
i++;
}
//paragraph.add(pdfPTable);
try {
document.add(pdfPTable);
}catch (Exception e){
log("paragraph", e);
}
}
These methods mentioned above are in a class:
public class TemplatePDF {
private Context context;
private File pdfFile;
private Document document;
public PdfWriter pdfWriter;
private Paragraph paragraph;
private Rotate event;
private Font fTitle = new Font(Font.FontFamily.TIMES_ROMAN, 20, Font.BOLD);
private Font fSubTitle = new Font(Font.FontFamily.TIMES_ROMAN, 18, Font.BOLD);
private Font fHeaderText = new Font(Font.FontFamily.TIMES_ROMAN, 3, Font.NORMAL, BaseColor.WHITE);
private Font fText = new Font(Font.FontFamily.TIMES_ROMAN, 3);
private Font fHText = new Font(Font.FontFamily.TIMES_ROMAN, 8);
private Font fHighText = new Font(Font.FontFamily.TIMES_ROMAN, 15, Font.BOLD, BaseColor.RED);
private float width = PageSize.A4.getWidth();
private float height = PageSize.A4.getHeight();
public float sizeImg;
public float sizeImgFit;
public TemplatePDF(Context context){
this.context = context;
}
public void openDocument(){
createFile();
try{
document = new Document(PageSize.A4);
pdfWriter = PdfWriter.getInstance(document, new FileOutputStream(pdfFile));
event = new Rotate();
document.open();
}catch (Exception e){
Log.e("erro", e.toString());
}
}
private void createFile(){
File folder = new File(Environment.getExternalStorageDirectory().toString(), "PDF");
if(!folder.exists()){
folder.mkdirs();
}
pdfFile = new File(folder, key() + ".pdf");
}
public void closeDocument(){
document.close();
}
...
}
To create PDF, I do so:
//Creating the object
TemplatePDF templatePDF = new TemplatePDF(ficha_pre.this);
templatePDF.openDocument();
templatePDF.addMetaData("Relatório", "Situs", "Woton Sampaio");
templatePDF.addTitles("Relatório", "","Data: " + getDate());
//Creating the table
ArrayList<String> header = new ArrayList<>();
for(int i = 0; i < 55; i++){
header.add(forString(i));
}
ArrayList<pdfItens> itens = arrayItens();
ArrayList<String[]> files = array();
templatePDF.createHeaderFicha(itens);
templatePDF.createTable(header, files);
//Adding image
templatePDF.addImg(R.drawable.ic_a, 0, 20, 566);
The cause for this is that an Image added to the Document is added in a virtual layer underneath that of regular text and tables. Apparently iText developers assumed that text and table elements by default are to be drawn in front of images.
But you can explicitly add the Image to a different virtual layer which is in turn above that of text and tables, in addImg you merely have to replace
document.add(image);
by
pdfWriter.getDirectContent().addImage(image);
Your image in addImg has its AbsolutePosition set. This actually is necessary for images you want to add to the DirectContent because the DirectContent has no idea about current insertion positions or page dimensions.
As an aside, there also is a DirectContentUnder for stuff that shall go even below the layer of Images added via the Document.

valueCell.addElement(img);

break;
default:
valueCell.setPhrase(new Phrase(val, cellFont));
}
return valueCell;
}
I'm using this code to insert in a cell some data, when the data is an image I use a switch to insert it.
Now I'm having some problems with a standard base64 image, its a Rectangle: 4160.0x3120.0 (rot: 0 degrees) but in the PDF build by my application this image is basically rotated by 90° and I'm pretty sure that I don't apply any kind of rotation to it.
I attach the Table creation:
public static PdfPTable createTableStructure(String groupTag) {
PdfPTable table = new PdfPTable(4);
table.setWidthPercentage(100);
table.getDefaultCell().setBorder(0);
PdfPCell headerCell = new PdfPCell();
headerCell.setBackgroundColor(new BaseColor(216, 216, 216)); //dark gray
headerCell.setBorder(Rectangle.NO_BORDER);
Font headerFont = FontFactory.getFont(FontFactory.HELVETICA, 14);
headerCell.setPhrase(new Phrase(groupTag, headerFont));
headerCell.setColspan(4);
table.addCell(headerCell);
table.setSpacingAfter(20);
table.setHeaderRows(1);
table.completeRow();
return table;
}
When a cell is ready I basically make this call:
table.addCell(valueCell);
Maybe the image is rotated on the original file.
try to check the Orientation. maybe you need to Rotate the image
[question]Get Image Orientation and rotate as per orientation
byte[] bytes = Convert.FromBase64String(val);

I have this code which creates a combobox in a PDF file. There are two problems with it.
Special characters (like ö) are displayed properly when the combobox is opened but then are not displayable when the combobox is closed.
When I open the PDF in Acrobat, change the value and save the PDF, the combobox is somehow gone. When I open the PDF again it is not displayed anymore.
Did I mess up something with the PDFBox classes or what may be the problem?
Here is a picture in the opened state:
and here is one in the closed state:
public class ComboTest {
public static void main(String[] args) {
PDFont font = PDType1Font.HELVETICA;
Color color = Color.BLACK;
float fontSize = 12;
PDDocument document = new PDDocument();
PDPage page = new PDPage(PDRectangle.A4);
document.addPage(page);
PDAcroForm acroForm = new PDAcroForm(document);
PDComboBox comboBox = new PDComboBox(acroForm);
comboBox.setPartialName("test");
String defaultAppearanceString = "/" + font.getName() + " " + fontSize + " Tf "
+ 0 + " " + 0 + " " + 0 + " rg";
comboBox.setDefaultAppearance(defaultAppearanceString);
PDAnnotationWidget widget = new PDAnnotationWidget();
widget.setRectangle(new PDRectangle(200, 200, 100, 20));
widget.setAnnotationFlags(4);
widget.setPage(page);
widget.setParent(comboBox);
List<String> exportValues = new ArrayList<>();
List<String> displayValues = new ArrayList<>();
displayValues.add("öne");
displayValues.add("two");
displayValues.add("thrée");
exportValues.add("1");
exportValues.add("2");
exportValues.add("3");
comboBox.setOptions(exportValues, displayValues);
List<PDAnnotationWidget> widgets = new ArrayList<>();
widgets.add(widget);
try {
page.getAnnotations().add(widget);
} catch (IOException e) {
e.printStackTrace();
}
comboBox.setWidgets(widgets);
try {
FileOutputStream output = new FileOutputStream("test.pdf");
document.save(output);
} catch (IOException e) {
e.printStackTrace();
}
}
}
Near the end of your code, add this:
acroForm.getFields().add(comboBox);
document.getDocumentCatalog().setAcroForm(acroForm);
this makes sure that your acroform and its field is known to the PDF.
Re the special character, replace the name of the Helvetica font with "Helv", which is a standard name for Adobe.
Better, cleaner solution: set up the default resources.
PDResources dr = new PDResources();
dr.put(COSName.getPDFName("Helv"), font);
acroForm.setDefaultResources(dr);
Instead of "Helv" you can also use COSName.getPDFName(font.getName()), but it has to be the same in your default appearance string.
So the full code is now:
public class ComboTest
{
public static void main(String[] args)
{
PDFont font = PDType1Font.HELVETICA;
Color color = Color.BLACK;
float fontSize = 12;
PDDocument document = new PDDocument();
PDPage page = new PDPage(PDRectangle.A4);
document.addPage(page);
PDAcroForm acroForm = new PDAcroForm(document);
PDComboBox comboBox = new PDComboBox(acroForm);
comboBox.setPartialName("test");
// Helv instead of Helvetica
String defaultAppearanceString = "/Helv " + fontSize + " Tf "
+ 0 + " " + 0 + " " + 0 + " rg";
comboBox.setDefaultAppearance(defaultAppearanceString);
PDAnnotationWidget widget = new PDAnnotationWidget();
widget.setRectangle(new PDRectangle(200, 200, 100, 20));
widget.setAnnotationFlags(4);
widget.setPage(page);
widget.setParent(comboBox);
List<String> exportValues = new ArrayList<>();
List<String> displayValues = new ArrayList<>();
displayValues.add("öne");
displayValues.add("two");
displayValues.add("thrée");
exportValues.add("1");
exportValues.add("2");
exportValues.add("3");
comboBox.setOptions(exportValues, displayValues);
List<PDAnnotationWidget> widgets = new ArrayList<>();
widgets.add(widget);
try
{
page.getAnnotations().add(widget);
}
catch (IOException e)
{
e.printStackTrace();
}
comboBox.setWidgets(widgets);
// new
acroForm.getFields().add(comboBox);
document.getDocumentCatalog().setAcroForm(acroForm);
PDResources dr = new PDResources();
dr.put(COSName.getPDFName("Helv"), font);
acroForm.setDefaultResources(dr);
try
{
FileOutputStream output = new FileOutputStream("test.pdf");
document.save(output);
}
catch (IOException e)
{
e.printStackTrace();
}
}

i am using following code to generate pdf file, everything is fine and working but i need to add watermark with the pdf file also alternate color to rows generated in pdf table.
response.setHeader("Content-disposition", "attachment; filename=\"" + reportName + ".pdf\"");
response.setContentType("application/pdf");
PdfWriter.getInstance(document,response.getOutputStream());
try {
document.open();
addTitlePage(document, reportName,path);
/* Image image = Image.getInstance(path+"images/abi.png");
image.setAbsolutePosition(40f, 770f);
image.scaleAbsolute(70f, 50f);
document.add(image);*/

int iterator = 1;
while (iterator <= headerMap.size()) {
if(iterator==1){
colsWidth.add(1.5f);
}else{

}
iterator++;
}
float[] floatArray = ArrayUtils.toPrimitive(colsWidth.toArray(new Float[0]), 0.0F);
PdfPTable table = new PdfPTable(floatArray);
table.setWidthPercentage(98);
table.setHorizontalAlignment(Element.ALIGN_CENTER);
PdfPCell c1 = new PdfPCell();
for (Iterator it = headerMap.keySet().iterator(); it.hasNext();) {

}
and this the method i use to create pdftable.(rows)
public PdfPTable creadPDFTable(String query,PdfPTable table){
int numberOfColumns=0,sno=1;
Connection connection = getConnection();
if (connection != null) {
try {
PreparedStatement reportTablePS = connection.prepareStatement(query);

ResultSetMetaData reportTable_rsmd = reportTable_rst.getMetaData();
numberOfColumns = reportTable_rsmd.getColumnCount();
while (reportTable_rst.next()) {
table.addCell(new PdfPCell(new Paragraph(String.valueOf(sno), textFont)));
for (int columnIterator = 1; columnIterator <= numberOfColumns; columnIterator++) {
String column = reportTable_rst.getString(columnIterator);
table.addCell(new PdfPCell(new Paragraph(column, textFont)));
}
sno++;
}
} catch (Exception ex) {
ex.printStackTrace();
}finally {
try {
closeConnection(connection, null, null);
} catch (Exception ex) {
ex.printStackTrace();
}
}
}
return table;
}
my main concern is to add watermark also adding alternate color to rows.
Please help to resolve this as i am unable to fix this for long time.
Regards
If you want add an watermark as a image u can use the code below. An other way to add a text watermark is to use annotations.
PdfReader pdfReader = null;
Stream outputStream = null;
PdfStamper pdfStamper = null;
try
{
pdfReader = GetPdfReaderObject();
outputStream = new FileStream(filePathDestination, FileMode.Create, FileAccess.Write, FileShare.None);
pdfStamper = new PdfStamper(pdfReader, outputStream);
PdfLayer layer = new PdfLayer("watermark", pdfStamper.Writer);
for (int pageIndex = 1; pageIndex <= pdfReader.NumberOfPages; pageIndex++) {
pdfStamper.FormFlattening = false;
iTextSharp.text.Rectangle pageRectangle = pdfReader.GetPageSizeWithRotation(pageIndex);
PdfContentByte pdfData = pdfStamper.GetOverContent(pageIndex);
pdfData.BeginLayer(layer);
PdfGState graphicsState = new PdfGState();
graphicsState.FillOpacity = 0.5F;
pdfData.SetGState(graphicsState);
pdfData.BeginText();
iTextSharp.text.Image watermarkImage = iTextSharp.text.Image.GetInstance(System.Drawing.Image.FromFile(watermarkImagePath), ImageFormat.Png);
float width = pageRectangle.Width;
float height = pageRectangle.Height;
watermarkImage.SetAbsolutePosition(width / 2 - watermarkImage.Width / 2, height / 2 - watermarkImage.Height / 2);
pdfData.AddImage(watermarkImage);
pdfData.EndText();
pdfData.EndLayer();
}
}
pdfStamper.Close();
outputStream.Close();
outputStream.Dispose();
pdfReader.Close();
pdfReader.Dispose();
} catch (Exception e) {
....
}
}
And not forget to remove the watermark if you want to add an other watermark.

when i use the following i get the following exception 'getoutputstream() has already called for this response'
i wanted to use this for inserting image.
Image image = Image.getInstance(path+"images/abi.png");
image.setAbsolutePosition(40f, 770f);
image.scaleAbsolute(70f, 50f);
document.add(image);
so how to go about doing this?
UPDATE :
i want to create a pdf file like this i just want to add image on the top and rows with alternate color like this.

You can use XSLFO and Apache FOP. It worked for me. For adding a image I done changes in XSL.
