I am trying to use PdfSmartCopy from ItextSharp but I cannot find any relevant examples in c#. The ideea is that I have a pdf containing form fields and the fields add 700kb to the size of the pdf document. The original document without form fields was 100kb. Any other sugestions are welcome, especially o reduce the pdf size consistently. (I optimised the generated PDF with adobe acrobat, and it reduced it to 44kb. So there must be a glitch somewhere.) Is there any way to reduce the PDF size? Edit: FormFlatenning doesn't . The pdf template file contains only text, lines and tables, no images.
here's my code snippet
PdfReader reader = new PdfReader(GetTemplateBytes());
pst = new PdfStamper(reader, Response.OutputStream);
var acroFields = pst.AcroFields;
pst.FormFlattening = true;
pst.FreeTextFlattening = true;
SetFieldsInternal(acroFields);
pst.Close();
I am trying to add an image to the top of every page on an existing PDF. I have tried using PdfStamp but for some reason when I try to print the pdf from Chrome all I get is a black page. Also Adobe Reader only shows the original document. Does anyone have any ideas on how to get it working? Here is the code.
public partial class MakePdf : System.Web.UI.Page { public MemoryStream m = new MemoryStream(); protected void Page_Load(object sender, EventArgs e) { Document document = new Document(PageSize.LETTER); Response.ContentType = "application/pdf"; string RESULT = @"C:UsersmaitchisonDocumentsPdfService Report Search - 650-10-067 4114.pdf"; PdfReader reader = new PdfReader(RESULT); PdfStamper stamp = new PdfStamper(reader, m); try { // Set ContentType and create an instance of the Writer. Response.ContentType = "application/pdf"; PdfWriter writer = PdfWriter.GetInstance(document, m); writer.CloseStream = false; // Open Document document.Open(); int n = reader.NumberOfPages; int i = 1; PdfContentByte cb = writer.DirectContent; PdfContentByte over; Barcode128 barcode128 = new Barcode128();................
So I have been using the open source library iTextSharp.dll for reading and writing to a pdf file. For the most part I've been developing an extension to an application which a user can select a pdf (as a template) and then be able to print a list of the labels for each field within the PDF so we can easily create backcode for how every different form will eventually be handled.
Now I have stepped forward into another application where I will be actually creating a print button which will print a populated pdf but will not save it. This is due to the fact our forms are permanently locked and a local copy of a filled form cannot be saved for security reasons. I'm having trouble printing the pdf and I actually do not even know if it is properly populating yet but I will deal with that once I can get it to print.
This is my code, where there is a function called "FillForm()". It locates the template file and the printable file and then utilizes a in-house function called "SelectString" which will return a string value for the value of a column within the database. All I really need to know is how to print the pdf once I am done.
I have web page named DocComments.aspx in which i created one table . one td contains document options for a pdf file which will be displayed in another td.I used iframe to display the td.
Document options are Move/copy-move a pdf file or create a pdf based on page number and range. Rotate page - rotate 90,180,270 Along with this option i need to add typewriter function in the pdf file which is going to load. I have used itextsharp dll for all the document options.Also i enabled the typewriter option in pdf file.If a user uses the typewriter and add comments,then i need to save that changes.I have stored all the pdf's in db. My problem is how to read that pdf file and save the changes using itextsharp.dll
I am creating an ASP.net website where some articles can be uploaded. I need that my users can get PDF version of it by clicking on a button. For this functionality I am using itextSharp. I am considering the following two options.
1. I will create the PDF file once(on first request) and reuse it always by checking for the existence of it.
2. I will create it on the fly and delete it as soon as the PDF file is delivered to the client. The first approach will lead to faster PDF delivery where as the second approach will lead to saving space.
I am also wondering if this can be possible without saving the PDF on the server in the first place.
I am looking for code to create a itextsharp pdf file using XML and xslt in an ASP.net application.I was unable find any code from the internet whihc uses xslt transform before converting to pdf.
i am trying to generate a pdf file using itextsharp in asp.net c#.
I came across table concept in itextsharp n i am trying to use it ie my application. I am having the following problem while using tables.The pdf cell which contains Name of treasery the word treasery comes on next line. I am setting width for each cell. if i increase the width than also no changes come. The gap which is shown using arrow in below image remain as it is al the time. Why is that gap?How to remove that gap?I want a dotted line as a border to only one cell. how to do that?here is my code
PdfPTable line6table = new PdfPTable (3); float[] width = new float[] { 2.5F, 1.5F, 3.0F }; line6table.SetWidths(width);[code]....
I'm working on dynamically filling in the fields on a pdf document using ITextSharp. I'd like to be able to determine the "export value" of the checkbox is from the codebehind in order to determine what value to send to this checkbox if it should be checked. Most of the documents I've worked with in the past had the same export value for every check box but the one I'm currently working with varies from checkbox to checkbox. I could go through all of the text boxes and make them consistent but it would save a lot of time in the future if I could just determine what the export value of these checkboxes are at runtime and set them accordingly.I tried to implement the solution below in C# and ended up with the following code:
i have use itextsharp to convert html to pdf(using asp.net C#) and its work in english characters , but when i want to convert html including arabic characters it will give me empty pdf !!
I am generating a pdf using iTextSharp. I would like to display it on the webpage and let the user save it from the online pdf viewer. dynamicpdf has a drawtoweb() method, but it is not free to use and I cannot find the same functionality using iTextSharp. How can I display the pdf?
string newFile = "Pdf Document.pdf"; Document doc = new Document(); PdfWriter writer = PdfWriter.GetInstance(doc, new FileStream(newFile, FileMode.Create)); doc.AddCreator("Myself"); doc.AddTitle("Sample PDF Document"); doc.Open(); doc.Add(new Paragraph("Hello, World!")); doc.Close();
i am using the above code for pdf generation from html text in HTMLEditor(ajax control). If i hardcode a table with each column of different width, into HTMLEditor text than while generating pdf the column get devided equally i.e all column have fixed size on pdf even if i specify some custom width for each column.
I want to generate pdf that can convert html to pdf,also divide table column with specified width. How to do it?
I want to convert my current asp.net page which will be running, to PDF when i click a button present on the page. I have buttons textboxes and text on the page. itextsharp.dll is not showing textboxs and buttons on the page its only showing plain html text.. what should i do?
I am using itextsharp-5.0.2-dll trying to create pdf from html. In that I am using HtmlParser, I dont know what should I import for this. still It getting error due to this.
I'm trying to export my gridview to pdf but the html parsing of the iTextSharp control seems to be failing. I have to create an HtmlForm like below and add the gridview to it because the code is in a custom control, so I cant pass the gridview directly. I get an error saying "gridview must be in a form tag with runat=server"
If I don't insert the test header like i do below, I get an error saying "document has no pages"
At the moment the pdf is generated but it only has the text "testing".
The htmlform html doesn't get parsed i think. Here is a small portion of what the newHtml variable below contains when I create it.
i'm genarating a pdf using itextsharp.in my gridview there are many feilds(100).i want to increase my page width. Document pdfDoc = new Document(PageSize.A1, 10f, 10f, 10f, 0f);
What I am doing is to generate a pdf booklet from database. I need go generate a content table with page numbers. E.g there are two chapters with page number like:
The text "Chapter 1 ----- " is normal paragraph. But the page number "3" has to be produced using PdfTemplate because it can only be known later. But the pdfTemplate is absolutely positioned. How can I know where to position the PdfTemplate? Am I right on this ? How could I figure this out or should I use other methods?
It is possible to create a PDF document in memory with iTextSharp that gives the user a choice to "open" or "save"?, and if it opens then it opens in a browser window.
At the moment the only I have save it to disk.
EDIT:
ok I've got it sussed. I did end up having to write the file to a folder, but it is only temporary as gets overwritten every time. Here is the solution for what it's worth:
private void GeneratePDF() { var doc1 = new Document(); string path = Server.MapPath("~/pdfs/"); string filepath = path + "Doc1.pdf"; PdfWriter.GetInstance(doc1, new FileStream(filepath, FileMode.Create));
I'm working on a project that involves exporting HTML to PDF. I was told that this can be accomplished with a a free library called ITextSharp:http://itextsharp.sourceforge.net/This looks like it's actually a JAVA-based interface. Does anyone know how to actually inistall this and reference these dlls in your ASP.Net project? Maybe there there's a different version of ITextSharp for .Net that I missed...
I am generating a pdf file in asp.net c# using itextsharp. i am not able to draw a horizontal line/verticle line/dotted line.
i tried to draw a line using the following code,i am getting no errors but the line is also not getting displayed in the pdf file
PdfContentByte cb = wri.DirectContent; cb.SetLineWidth(2.0f); // Make a bit thicker than 1.0 default cb.MoveTo(20, pdfDocument.Top - 40f); cb.LineTo(400, pdfDocument.Top - 40f); cb.Stroke();
What is the problem in the code.Is it because of the position of x y co-ordinates? I had used rough points to know approximate position in pdf,but the line never apears in the pdf file.
The output i am looking out for is as shown in image below.
