I'm trying to convert html to pdf using iTextSharp.dll. Although on the output pdf document, it renders the html markup without formatted text. Please tell me what am I missing.
Document pdfDoc = new Document(PageSize.A4, 50, 50, 25, 25);
var textInput = Label1.Text;
try
{
var output = new MemoryStream();
var writer = PdfWriter.GetInstance(pdfDoc, output);
pdfDoc.Open();
var logo = iTextSharp.text.Image.GetInstance(Server.MapPath("~/Image/image1.jpg"));
logo.SetAbsolutePosition(400, 750);
pdfDoc.Add(logo);
Paragraph para = new Paragraph(textInput);
para.Alignment = Element.PARAGRAPH;
pdfDoc.Add(para);
Response.ContentType = "application/pdf";
Response.AddHeader("Content-Disposition", string.Format("attachment;filename=Doc-{0}.pdf", TextBox3.Text));
Response.BinaryWrite(output.ToArray());
}
catch (DocumentException dex)
{
throw (dex);
}
catch (IOException ioex)
{
throw (ioex);
}
finally
{
pdfDoc.Close();
}
}
I would greatly appreciate any help.

I am using iTextSharp library for HTML to PDF conversion.
Could you suggest why following HTML+CSS is not converted to PDF properly? Looks like elements margins are not applied at all…Text is stuck to the left. Browser (Chrome) centers it fine.
CSS:
#sgh-mainC {
width: 100px;
margin-top: 0;
margin-bottom: 0;
margin-right: auto;
margin-left: auto;
}
HTML:
<!DOCTYPE html>
<html lang="en">
<head>
<title>PDS</title>
</head>
<body>
<div id="sgh-mainC">
text that should be centered
</div>
</body>
</html>
C#:
private void CreatePdf(string html, string css)
{
try
{
Byte[] bytes;
using (var ms = new MemoryStream())
{
using (var doc = new Document())
{
using (var writer = PdfWriter.GetInstance(doc, ms))
{
doc.Open();
var cssResolver = new StyleAttrCSSResolver();
var msCss = XMLWorkerHelper.GetCSS(new MemoryStream(System.Text.Encoding.UTF8.GetBytes(css)));
cssResolver.AddCss(msCss);
HtmlPipelineContext htmlContext = new HtmlPipelineContext(null);
htmlContext.SetTagFactory(Tags.GetHtmlTagProcessorFactory());
htmlContext.AutoBookmark(false);
var htmlStream = new MemoryStream(System.Text.Encoding.UTF8.GetBytes(html));
PdfWriterPipeline pdfPpl = new PdfWriterPipeline(doc, writer);
HtmlPipeline htmlPpl = new HtmlPipeline(htmlContext, pdfPpl);
CssResolverPipeline cssPpl = new CssResolverPipeline(cssResolver, htmlPpl);
new XMLParser(new XMLWorker(cssPpl, true)).Parse(htmlStream);
doc.Close();
}
}
bytes = ms.ToArray();
}
if (File.Exists(FilePath))
{
File.Delete(FilePath);
}
var file = File.Create(FilePath);
file.Write(bytes, 0, bytes.Count());
file.Close();
}
catch (Exception exc)
{
//TODO log errror
}
}
Thank you.

This questions is a bit old, however in case anyone else stumbles across this post...
It appears there is a very limited set of CSS that iTextSharp actually supports. You can find it at http://demo.itextsupport.com/xmlworker/itextdoc/CSS-conformance-list.htm
I'm currently searching for a library or a way to convert HTML OR DOCX files into PDF on the phone/tab, primarily I'am searching for a way on Android or iOS idk if its a PCL or platform specific approach. I could do this for every Platform independently, because our app requires iOS 8 or android kitkat, both supporting native PDF conversion but i want to do it seamless for the user, so the question is, if anyone has done this before, without loading it into a visible Webview at first or has knowledge of an open not GPL licensed API(can't publish the code), to do this with Xamarin.
I am aware of the possibility to do this online, but I don't want to to be dependent to a online service for this.
Help and ideas are appreciated.
Android Solution:
Call the SafeHTMLToPDF(string html, string filename) via a dependency service like
DependencyService.Get<YOURINTERFACE>().SafeHTMLToPDF(htmlString, "Invoice");
public string SafeHTMLToPDF(string html, string filename)
{
var dir = new Java.IO.File(Android.OS.Environment.ExternalStorageDirectory.AbsolutePath + "/pay&go/");
var file = new Java.IO.File(dir + "/" + filename + ".pdf");
if (!dir.Exists())
dir.Mkdirs();
int x = 0;
while (file.Exists())
{
x++;
file= new Java.IO.File(dir + "/" + filename + "( " + x + " )" + ".pdf");
}
if (webpage == null)
webpage = new Android.Webkit.WebView(GetApplicationContext());
int width = 2102;
int height = 2973;
webpage.Layout(0, 0, width, height);
webpage.LoadDataWithBaseURL("",html, "text/html", "UTF-8" , null);
webpage.SetWebViewClient(new WebViewCallBack(file.ToString()));
return file.ToString();
}
class WebViewCallBack : WebViewClient
{
string fileNameWithPath = null;
public WebViewCallBack(string path)
{
this.fileNameWithPath = path;
}
public override void OnPageFinished(Android.Webkit.WebView myWebview, string url)
{
PdfDocument document = new PdfDocument();
PdfDocument.Page page = document.StartPage(new PdfDocument.PageInfo.Builder(2120 ,3000, 1).Create());
myWebview.Draw(page.Canvas);
document.FinishPage(page);
Stream filestream = new MemoryStream();
FileOutputStream fos = new Java.IO.FileOutputStream(fileNameWithPath, false); ;
try
{
document.WriteTo(filestream);
fos.Write(((MemoryStream)filestream).ToArray(), 0, (int)filestream.Length);
fos.Close();
}
catch
{
}
}
}
And the Way to do it under iOS
public string SafeHTMLToPDF(string html, string filename)
{
UIWebView webView = new UIWebView(new CGRect(0, 0, 6.5 * 72, 9 * 72));
var documents = Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments);
var file = Path.Combine(documents, "Invoice" + "_" + DateTime.Now.ToShortDateString() + "_" + DateTime.Now.ToShortTimeString() + ".pdf");
webView.Delegate = new WebViewCallBack(file);
webView.ScalesPageToFit = true;
webView.UserInteractionEnabled = false;
webView.BackgroundColor = UIColor.White;
webView.LoadHtmlString(html, null);
return file;
}
class WebViewCallBack : UIWebViewDelegate
{
string filename = null;
public WebViewCallBack(string path)
{
this.filename = path;
}
public override void LoadingFinished(UIWebView webView)
{
double height, width;
int header, sidespace;
width = 595.2;
height = 841.8;
header = 10;
sidespace = 10;
UIEdgeInsets pageMargins = new UIEdgeInsets(header, sidespace, header, sidespace);
webView.ViewPrintFormatter.ContentInsets = pageMargins;
UIPrintPageRenderer renderer = new UIPrintPageRenderer();
renderer.AddPrintFormatter(webView.ViewPrintFormatter, 0);
CGSize pageSize = new CGSize(width, height);
CGRect printableRect = new CGRect(sidespace,
header,
pageSize.Width - (sidespace * 2),
pageSize.Height - (header * 2));
CGRect paperRect = new CGRect(0, 0, width, height);
renderer.SetValueForKey(NSValue.FromObject(paperRect), (NSString)"paperRect");
renderer.SetValueForKey(NSValue.FromObject(printableRect), (NSString)"printableRect");
NSData file = PrintToPDFWithRenderer(renderer, paperRect);
File.WriteAllBytes(filename, file.ToArray());
}
private NSData PrintToPDFWithRenderer(UIPrintPageRenderer renderer, CGRect paperRect)
{
NSMutableData pdfData = new NSMutableData();
UIGraphics.BeginPDFContext(pdfData, paperRect, null);
renderer.PrepareForDrawingPages(new NSRange(0, renderer.NumberOfPages));
CGRect bounds = UIGraphics.PDFContextBounds;
for (int i = 0; i < renderer.NumberOfPages; i++)
{
UIGraphics.BeginPDFPage();
renderer.DrawPage(i, paperRect);
}
UIGraphics.EndPDFContent();
return pdfData;
}
}
Frustrated with the existing solutions, I've built some extension methods (OpenSource, MIT Licensed) that convert HTML or the content of a Xamarin.Forms.WebView to a PDF file. Sample usage for WebView to PDF:
async void ShareButton_Clicked(object sender, EventArgs e)
{
if (Forms9Patch.ToPdfService.IsAvailable)
{
if (await webView.ToPdfAsync("output.pdf") is ToFileResult pdfResult)
{
if (pdfResult.IsError)
using (Toast.Create("PDF Failure", pdfResult.Result)) { }
else
{
var collection = new Forms9Patch.MimeItemCollection();
collection.AddBytesFromFile("application/pdf", pdfResult.Result);
Forms9Patch.Sharing.Share(collection, shareButton);
}
}
}
else
using (Toast.Create(null, "PDF Export is not available on this device")) { }
}
}
For a more complete explanation of how to use it, here's a short article: https://medium.com/#ben_12456/share-xamarin-forms-webview-as-a-pdf-a877542e824a?
You can able to convert the HTML to PDF file without any third party library. I am sharing my git repo for future reference.
https://github.com/dinesh4official/XFPDF
Yes, you can convert a Word document to PDF in Xamarin with a few lines of code easily. You need to refer Syncfusion.Xamarin.DocIORenderer from nuget.org
Assembly assembly = typeof(App).GetTypeInfo().Assembly;
// Retrieves the document stream from embedded Word document
Stream inputStream = assembly.GetManifestResourceStream("WordToPDF.Assets.GettingStarted.docx");
string fileName = "GettingStarted.pdf";
// Creates new instance of WordDocument
WordDocument wordDocument = new WordDocument(inputStream,Syncfusion.DocIO.FormatType.Automatic);
inputStream.Dispose();
// Creates new instance of DocIORenderer for Word to PDF conversion
DocIORenderer render = new DocIORenderer();
// Converts Word document into PDF document
PdfDocument pdfDocument = render.ConvertToPDF(wordDocument);
// Releases all resources used by the DocIORenderer and WordDocument instance
render.Dispose();
document.Close();
// Saves the converted PDF file
MemoryStream outputStream = new MemoryStream();
pdfDocument.Save(outputStream);
// Releases all resources used by the PdfDocument instance
pdfDocument.Close();

Hello guys I am generating a Payment Invoice order in PDF from my html content and sending it by e-mail with the following code:
***//Generates PDF Payment Invoice***
StringBuilder sb = new StringBuilder();
sb.Append(#"<meta http-equiv=""Content-Type"" content=""text/html; charset=utf-8"">");
sb.Append(boletoBancario.MontaHtml());
StringReader sr = new StringReader(sb.ToString());
Document pdfDoc = new Document(PageSize.A4, 10f, 10f, 10f, 0f);
HTMLWorker htmlparser = new HTMLWorker(pdfDoc);
byte[] bytes;
memoryStream = new MemoryStream();
PdfWriter writer = PdfWriter.GetInstance(pdfDoc, memoryStream);
pdfDoc.Open();
iTextSharp.text.html.simpleparser.StyleSheet ST = new iTextSharp.text.html.simpleparser.StyleSheet();
ST.LoadTagStyle("body", "encoding", "Identity-H");
htmlparser.SetStyleSheet(ST);
htmlparser.Parse(sr);
pdfDoc.Close();
bytes = memoryStream.ToArray();
memoryStream.Close();
memoryStream = new MemoryStream(bytes);
***//Sends E-mail with PDF PAYMENT INVOICE Attached***

mensagem.Attachments.Add(att);
mensagem.Subject = "Payment Invoice";
mensagem.Body = String.Format("Your payment invoice is available.");
mensagem.IsBodyHtml = true;
smtp.UseDefaultCredentials = true;
smtp.EnableSsl = false;
smtp.Send(mensagem);
The problem is that the PDF attached to the email does not render correctly the HTML so it stills unformmated. Otherwise when i create a blank file and put the entire HTML and open it using Chrome it's pretty well formated.
I need to get this PDF correctly attached to the e-mail.
Could somebody help me?Here You can see the Rendering Problem
Finally I've found the solution to my problem!
It was necessary to use itextSharp.xmlWorker library and do some changes in the code-behind. The reason is HTMLWorker really does not resolve CSS, so I had to use XMLWorker instead and do like following:
//Geração de PDF
StringBuilder sb = new StringBuilder();
StringReader sr;
Document pdfDoc;
PdfWriter writer;
byte[] bytes;
sb.Append(boletoBancario.MontaHtml());
sr = new StringReader(sb.ToString().Replace("<br />","<b></b>").Replace("<br>","<br></br>"));
pdfDoc = new Document(PageSize.A4, 30, 30, 30, 30);
writer = PdfWriter.GetInstance(pdfDoc, memoryStream);
HtmlPipelineContext htmlContext = new HtmlPipelineContext(null);
htmlContext.SetTagFactory(Tags.GetHtmlTagProcessorFactory());
ICSSResolver cssResolver = XMLWorkerHelper.GetInstance().GetDefaultCssResolver(false);
IPipeline pipeline = new CssResolverPipeline(cssResolver, new HtmlPipeline(htmlContext, new PdfWriterPipeline(pdfDoc, writer)));
XMLWorker worker = new XMLWorker(pipeline, true);
XMLParser xmlParser = new XMLParser(worker);
pdfDoc.Open();
xmlParser.Parse(sr);
pdfDoc.Close();
bytes = memoryStream.ToArray();
memoryStream.Close();
return new MemoryStream(bytes);
Thanks you all btw!
I would like to create dynamic PDF documents using HTML and dynamic images. My code works fine with standard HTML and full paths for the images, but when I try to embed the image inline in the document I get the error
Exception Details: System.IO.IOException: The document has no pages.
Is there a way to embed the images without an HTTP call per image? I don't want that because I think it will cause scalability issues and the images are sensitive.
Here is my code that gives the IOException:

We need to write our own ImageTagProcessor to support processing of base 64 images:
public class CustomImageTagProcessor : iTextSharp.tool.xml.html.Image
{
public override IList<IElement> End(IWorkerContext ctx, Tag tag, IList<IElement> currentContent)
{
IDictionary<string, string> attributes = tag.Attributes;
string src;
if (!attributes.TryGetValue(HTML.Attribute.SRC, out src))
return new List<IElement>(1);
if (string.IsNullOrEmpty(src))
return new List<IElement>(1);
if (src.StartsWith("data:image/", StringComparison.InvariantCultureIgnoreCase))
{
// data:[<MIME-type>][;charset=<encoding>][;base64],<data>
var base64Data = src.Substring(src.IndexOf(",") + 1);
var imagedata = Convert.FromBase64String(base64Data);
var image = iTextSharp.text.Image.GetInstance(imagedata);
var list = new List<IElement>();
var htmlPipelineContext = GetHtmlPipelineContext(ctx);
list.Add(GetCssAppliers().Apply(new Chunk((iTextSharp.text.Image)GetCssAppliers().Apply(image, tag, htmlPipelineContext), 0, 0, true), tag, htmlPipelineContext));
return list;
}
else
{
return base.End(ctx, tag, currentContent);
}
}
}
Then we can inject this new processor into the HtmlPipelineContext:
using (var doc = new Document(PageSize.A4))
{

I am making a game on cocos2d-JS for facebook in which there is a requirement of sharing a screenshot of the game.
I am able to take the screenshot but now I am unable to upload it in the Parse.com server because it requires base64 format or byte array. I am unable to find any solution of converting Sprite in to this format.. Here's my code so result when I do addchild its coming proper .. I have also added my commented code so that it will help to understand that I have tried lot of things but couldnt achieve the same.
shareToSocialNetworking: function () {
cc.director.setNextDeltaTimeZero(true);
var newsize = cc.director.getVisibleSize();
var renderText = new cc.RenderTexture(newsize.width,newsize.height);
renderText.begin();
cc.director.getRunningScene().visit();
renderText.end();
var result = cc.Sprite.create(renderText.getSprite().getTexture());
result.flippedY = true;
this._mainViewNode.addChild(result,6000);
//renderText.saveToFile("screenshot.jpg",cc.IMAGE_FORMAT_PNG);
//var based = renderText.getSprite().getTexture().getStringForFormat().toString();
//var data = based.getData();
var file = new Parse.File("screen.jpg", { base64: this.getBase64(result) });
//var file = new Parse.File("screen.jpg", data, "image/png");
var self = this;
file.save().then(function() {
// The file has been saved to Parse.
alert(file.url);
this.onSharePictureInfoLink(file.url());
}, function(error) {
// The file either could not be read, or could not be saved to Parse.
});
//
//var ccImage = renderText.newCCImage();
//
//var str = ccImage.getData();
},
is there any workaround that can be done
there is a private variable called _cacheCanvas, which is the instance of the offscreen canvas
you can simply do renderText._cacheCanvas.toDataURL()
Here's how you can take the screnshot from cocos2d-JS
screenshot: function (fileName) {
var tex = new cc.RenderTexture(winSize.width, winSize.height, cc.Texture2D.PIXEL_FORMAT_RGBA8888);
tex.setPosition(cc.p(winSize.width / 2, winSize.height / 2));
tex.begin();
cc.director.getRunningScene().visit();
tex.end();
var imgPath = jsb.fileUtils.getWritablePath();
if (imgPath.length == 0) {
return;
}
var result = tex.saveToFile(fileName, cc.IMAGE_FORMAT_JPEG);
if (result) {
imgPath += fileName;
cc.log("save image:" + imgPath);
return imgPath;
}
return "";
}
then make a Java call from Javascript
public static void ScreenShot()
{
Bitmap imageBitmap = BitmapFactory.decodeFile(Cocos2dxHelper.getCocos2dxWritablePath() + "/" + "screenshot.png");
String fileHolder = "SampleFolder";
File filepathData = new File("/sdcard/" + fileHolder);
//~~~Create Dir
try {
if (!filepathData.exists())
{
filepathData.mkdirs();
filepathData.createNewFile();
FileWriter fw = new FileWriter(filepathData + fileHolder);
BufferedWriter out = new BufferedWriter(fw);
String toSave = String.valueOf(0);
out.write(toSave);
out.close();
}
}
catch (IOException e1) {
}
//~~~Create Image
File file = new File("/sdcard/" + "Your filename");
try
{
file.createNewFile();
FileOutputStream ostream = new FileOutputStream(file);
imageBitmap.compress(CompressFormat.PNG, 100, ostream);
ostream.close();
}
catch (Exception e) {}
Uri phototUri = Uri.fromFile(file);
Intent shareIntent = new Intent();
shareIntent.setAction(Intent.ACTION_SEND);
shareIntent.putExtra(Intent.EXTRA_STREAM, phototUri);
//~~~Add Code Below
}
Do not forget to add permission for external storage
