I am using Expert PDF to generate PDF from HTML.
I have to generate footer on all pages except on the first page.
I tried with:
PdfConverter pdfConverter = new PdfConverter();
AddFooter(pdfConverter);
private void AddFooter(PdfConverter pdfConverter)
{
string thisPageURL = HttpContext.Current.Request.Url.AbsoluteUri;
string headerAndFooterHtmlUrl = thisPageURL.Substring(0, thisPageURL.LastIndexOf('/')) + "/HeaderAndFooterHtml.htm";
//enable footer
pdfConverter.PdfDocumentOptions.ShowFooter = true;
// set the footer height in points
pdfConverter.PdfFooterOptions.FooterHeight = 60;
//write the page number
pdfConverter.PdfFooterOptions.TextArea = new TextArea(0, 30, "This is page &p; of &P; ",
new System.Drawing.Font(new System.Drawing.FontFamily("Times New Roman"), 10, System.Drawing.GraphicsUnit.Point));
pdfConverter.PdfFooterOptions.TextArea.EmbedTextFont = true;
pdfConverter.PdfFooterOptions.TextArea.TextAlign = HorizontalTextAlign.Right;
// set the footer HTML area
pdfConverter.PdfFooterOptions.HtmlToPdfArea = new HtmlToPdfArea(0, 0, -1, pdfConverter.PdfFooterOptions.FooterHeight,
headerAndFooterHtmlUrl, 1024, -1);
pdfConverter.PdfFooterOptions.HtmlToPdfArea.FitHeight = true;
}
but this code generate footer on all pages.
Can someone give me idea or solution for this problem?
Thanks in advance!
Add below line in your code:
pdfConverter.PdfFooterOptions.ShowOnFirstPage = false;

I have to put my list data in a table in a pdf file. My data has some Arabic words. When my pdf is generated, the Arabic words don't appear. I searched and found that I need itext7.pdfcalligraph so I installed it in my app. I found this code too https://itextpdf.com/en/blog/technical-notes/displaying-text-different-languages-single-pdf-document and tried to do something similar to allow Arabic words in my table but I couldn't figure it out.
This is a trial code before I apply it to my real list:
var path2 = global::Android.OS.Environment.ExternalStorageDirectory.AbsolutePath;
filePath = System.IO.Path.Combine(path2.ToString(), "myfile2.pdf");
stream = new FileStream(filePath, FileMode.Create);
PdfWriter writer = new PdfWriter(stream);
PdfDocument pdf2 = new iText.Kernel.Pdf.PdfDocument(writer);
Document document = new Document(pdf2, PageSize.A4);
FontSet set = new FontSet();
set.AddFont("ARIAL.TTF");
document.SetFontProvider(new FontProvider(set));
document.SetProperty(Property.FONT, "Arial");
string[] sources = new string[] { "يوم","شهر 2020" };
iText.Layout.Element.Table table = new iText.Layout.Element.Table(2, false);
foreach (string source in sources)
{
Paragraph paragraph = new Paragraph();
Bidi bidi = new Bidi(source, Bidi.DirectionDefaultLeftToRight);
if (bidi.BaseLevel != 0)
{
paragraph.SetTextAlignment(iText.Layout.Properties.TextAlignment.RIGHT);
}
paragraph.Add(source);
table.AddCell(new Cell(1, 1).SetTextAlignment(iText.Layout.Properties.TextAlignment.CENTER).Add(paragraph));
}
document.Add(table);
document.Close();
I updated my code and added the arial.ttf to my assets folder . i'm getting the following exception:
System.InvalidOperationException: 'FontProvider and FontSet are empty. Cannot resolve font family name (see ElementPropertyContainer#setFontFamily) without initialized FontProvider (see RootElement#setFontProvider).'
and I still can't figure it out. any ideas?
thanks in advance

I have a similar situation for Turkish characters, and I've followed these
steps :
Create a folder under projects root folder which is : /wwwroot/Fonts
Add OpenSans-Regular.ttf under the Fonts folder
Path for font is => ../wwwroot/Fonts/OpenSans-Regular.ttf
Create font like below :
public static PdfFont CreateOpenSansRegularFont()
{
var path = "{Your absolute path for FONT}";
return PdfFontFactory.CreateFont(path, PdfEncodings.IDENTITY_H, true);
}
and use it like :
paragraph.Add(source)
.SetFont(FontFactory.CreateOpenSansRegularFont()); //set font in here
table.AddCell(new Cell(1, 1)
.SetTextAlignment(iText.Layout.Properties.TextAlignment.CENTER)
.Add(paragraph));
This is how I used font factory for Turkish characters ex: "ü,i,ç,ş,ö"
For Xamarin-Android, you could try
string documentsPath = Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments);
var path = Path.Combine(documentsPath, "Fonts/Arial.ttf");
Look i fixed it in java,this may help you:
String font = "your Arabic font";
//the magic is in the next 4 lines:
PdfFontFactory.register(font);
FontProgram fontProgram = FontProgramFactory.createFont(font, true);
PdfFont f = PdfFontFactory.createFont(fontProgram, PdfEncodings.IDENTITY_H);
LanguageProcessor languageProcessor = new ArabicLigaturizer();
//and look here how i used setBaseDirection and don't use TextAlignment ,it will work without it
com.itextpdf.kernel.pdf.PdfDocument tempPdfDoc = new com.itextpdf.kernel.pdf.PdfDocument(new PdfReader(pdfFile.getPath()), TempWriter);
com.itextpdf.layout.Document TempDoc = new com.itextpdf.layout.Document(tempPdfDoc);
com.itextpdf.layout.element.Paragraph paragraph0 = new com.itextpdf.layout.element.Paragraph(languageProcessor.process("الاستماره الالكترونية--الاستماره الالكترونية--الاستماره الالكترونية--الاستماره الالكترونية"))
.setFont(f).setBaseDirection(BaseDirection.RIGHT_TO_LEFT)
.setFontSize(15);
I can not find any direct Apache POI code for setting the values of header from top and footer from bottom in a word file.Please give me some suggestion for setting these values using java code.
I too have been looking for the answer to this question for quite some time and came across this answer but sadly forget where.
I hope this helps someone too.

I am trying to generate the barcode from barcode4j library(code128bean, other barcode beans) and try to add to the existing pdf. The barcode image is getting created locally using the below code.
//Create the barcode bean
Code128Bean code128Bean = new Code128Bean();
final int dpi = 150;
code128Bean.setModuleWidth(UnitConv.in2mm(1.0f / dpi)); //makes the narrow bar
//width exactly one pixel
//bean.setCodeset(2);
code128Bean.doQuietZone(false);
//Open output file
File outputFile = new File("D:/barcode4jcod128.png"); //I dont want to create it
OutputStream code128Stream = new FileOutputStream(outputFile);
try {
//Set up the canvas provider for monochrome PNG output
BitmapCanvasProvider canvas1 = new BitmapCanvasProvider(
code128Stream, "image/x-png", dpi, BufferedImage.TYPE_BYTE_BINARY, false, 0);
//Generate the barcode
code128Bean.generateBarcode(canvas1, "123456");
//Signal end of generation
canvas1.finish();
} finally {
code128Stream.close();
}
My problem is I don't want to create an image and save it locally in filesystem and then add it as image to pdf. I just want to create dynamically i mean just create the barcode image dynamically and add it to the pdf.
How do I set the pagesize (like PDPage.PAGE_SIZE_A4) to the existing PDPages which I retrieved from catalog.getAllPages() method, like (List<PDPage> pages = catalog.getAllPages();)
Can somebody help on this?
Thank you so much for your help Tilman. Here is what i did
public static BufferedImage geBufferedImageForCode128Bean(String barcodeString) {
Code128Bean code128Bean = new Code128Bean();
final int dpi = 150;
code128Bean.setModuleWidth(UnitConv.in2mm(1.0f / dpi)); //makes the narrow bar
code128Bean.doQuietZone(false);
BitmapCanvasProvider canvas1 = new BitmapCanvasProvider(
dpi, BufferedImage.TYPE_BYTE_BINARY, false, 0
);
//Generate the barcode
code128Bean.generateBarcode(canvas1, barcodeString);
return canvas1.getBufferedImage();
}
// main code
PDDocument finalDoc = new PDDocument();
BufferedImage bufferedImage = geBufferedImageForCode128Bean("12345");
PDXObjectImage pdImage = new PDPixelMap(doc, bufferedImage);
PDPageContentStream contentStream = new PDPageContentStream(
finalDoc, pdPage, true, true, true
);
contentStream.drawXObject(pdImage, 100, 600, 50, 20);
contentStream.close();
finalDoc.addPage(pdPage);
finalDoc.save(new File("D:/Test75.pdf"));
The barcode is getting created the but it is created in vertical manner. i would like to see in horizontal manner. Thanks again for your help.
1) add an image to an existing page while keeping the content:
BitmapCanvasProvider canvas1 = new BitmapCanvasProvider(
dpi, BufferedImage.TYPE_BYTE_BINARY, false, 0
);
code128Bean.generateBarcode(canvas1, "123456");
canvas1.finish();
BufferedImage bim = canvas1.getBufferedImage();
PDXObjectImage img = new PDPixelMap(doc, bim);
PDPageContentStream contents = new PDPageContentStream(doc, page, true, true, true);
contents.drawXObject(img, 100, 600, bim.getWidth(), bim.getHeight());
contents.close();
2) set the media box to A4 on an existing page:
page.setMediaBox(PDPage.PAGE_SIZE_A4);
I deal with dynamic input text, so the pages should be dynamically created. If page 1 is already full, it should write to a new page, so it means I can have page 2, page 3 and so on depending on the data processed.
Currently, my text is truncated. Only writes Page 1, the rest of data are not written.
My current code below:
//add page 1
theDoc.Page = theDoc.AddPage();
theDoc.AddImageHtml(html, true, 826, true);
//continue adding page if needed
while (theDoc.GetInfo(theID, "Truncated") == "1")
{
theDoc.Page = theDoc.AddPage();
theDoc.AddImageHtml(html, true, 826, true);
}
//save file
String pdfFilePath = WebConfigurationManager.AppSettings["pdfFilePath"];
Guid fileName = Guid.NewGuid();
pdfLink = pdfFilePath + fileName.ToString() + ".pdf";
theDoc.Save(pdfLink);
theDoc.Clear();
variable html contains all the data(webpage), I'm probably missing something in my while loop. Any help is appreciated! Thanks
Found it, Use Chainable and then Flatten()
theDoc.Page = theDoc.AddPage();
int theID;
theID = theDoc.AddImageUrl("http://www.yahoo.com/");
while (true) {
theDoc.FrameRect(); // add a black border
if (!theDoc.Chainable(theID))
break;
theDoc.Page = theDoc.AddPage();
theID = theDoc.AddImageToChain(theID);
}
for (int i = 1; i <= theDoc.PageCount; i++) {
theDoc.PageNumber = i;
theDoc.Flatten();
}
I am using an sdk from pdftron,which reads a single page at a time. My code would be:
PDFDoc doc = new PDFDoc(input_path);
doc.InitSecurityHandler();
PageIterator itr = doc.GetPage(1);
for (line = txt.GetFirstLine(); line.IsValid(); line = line.GetNextLine()){
for (word = line.GetFirstWord(); word.IsValid(); word = word.GetNextWord()){
Console.WriteLine(word.GetString());
}
}
I want to read each and every page, I had posted my same problem in PDFTRON forums.But couldn't get the solution for this.
Is it possible to read each and every pages?
Yes,you can read each and every pages of pdf at a time.You need to do just s slight change initializing page iterator.
I have modified the code,and it works fine.
PDFDoc doc = new PDFDoc(input_path);
doc.InitSecurityHandler();
PageIterator itr = doc.GetPageIterator();
for (; itr.HasNext(); itr.Next()) // Read every page
{
for (line = txt.GetFirstLine(); line.IsValid(); line = line.GetNextLine())
{
for (word = line.GetFirstWord(); word.IsValid(); word = word.GetNextWord())
{
Console.WriteLine(word.GetString());
}
}
}
Hope this will help you.
