itextsharp

Is it possible to use itextsharp to convert postscript to a PDF ? If not is there another way to do it in .net ? Converting PostScript to PDF is called "distilling". iText and iTextSharp do not support distilling. Ghostscript will be your only FOSS solution. You could use Ghostscript as it's explained here: http://hi.baidu.com/lqyidxa_igfv/blog/item/df2037b394539fa0d9335a94.html 来源： https://stackoverflow.com/questions/4970511/itextsharp-postscript-to-pdf

I've looked up some documentations and examples under the http://developers.itextpdf.com/examples . I know iText is able to generate tagged pdf from scratch, but is it possible to insert alternative text to images in an existing tagged pdf (without changing anything else)? I need to implement this feature in a program without using GUI applications (such as Adobe Acrobat Pro). Thanks. Please take a look at the AddAltTags example. In this example, we take a PDF with images of a fox and a dog where the Alt keys are missing: no_alt_attribute.pdf Code can't recognize a fox or a dog, so we create a

i have a tree view in which there are certain set of document list and another grid having patient details. what i need to do is when we select docs from treeview (select multiple..checkbox enabled) and patients from grid and click on a button should create all the documents using ITEXTSHARP.that is multiple documents are created. I tried it like this, on button click foreach( TreeNode node in TreeView1.Nodes) { if (node.ChildNodes.Count>0) { for(int i=0 ;i<(node.ChildNodes.Count);i++) { if (node.ChildNodes[i].Checked==true) { string nodevalue = node.ChildNodes[i].Value.ToString(); if

Adobe Acrobat has the option to lock the PDF document after signing it. This changes the document permissions so that Acrobat does not offer signing the document again or modifying annotations or forms. This seems like a reasonable action to do after a document has been signed for review by multiple entities and finally for release by someone responsible. iTextSharp can also sign documents, and it can also add further signatures to an already signed document. iTextSharp basically also can set the document's permissions, but somehow I can't get it to set the same permissions as Acrobat X Pro

I have a problem trying to apply a css file to my pdf using the iTextSharp (5.4.3) generation library. basically the css is not being applied at all. I have the following method in my vb.net file Protected Sub btnPreview_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnPreview.Click Dim bytes As Byte() bytes = System.Text.Encoding.UTF8.GetBytes(letterRadEdit.Content) Dim tagProcessor As tool.xml.html.DefaultTagProcessorFactory() Using input As New MemoryStream(bytes, False) Dim ms As New MemoryStream() Dim document As New iTextSharp.text.Document(iTextSharp.text.PageSize

I want to make my background image in iText transparent here is my code for the image: string root = Server.MapPath("~"); string parent = Path.GetDirectoryName(root); string grandParent = Path.GetDirectoryName(parent); string imageFilePath = parent + "/Images/logo.png"; iTextSharp.text.Image jpg = iTextSharp.text.Image.GetInstance(imageFilePath); jpg.ScaleToFit(1700, 800); jpg.Alignment = iTextSharp.text.Image.UNDERLYING; jpg.SetAbsolutePosition(100, 250); jpg.ScaleAbsoluteHeight(500); jpg.ScaleAbsoluteWidth(500); Any idea? Please take a look at the BackgroundTransparant example. It is a

How would I merge several pdf pages into one with iTextSharp which also supports merging pages having form elements like textboxes , checkboxes , etc. I have tried so many by googling, but nothing has worked well. Jonathan See my answer here Merging Memory Streams . I give an example of how to merge PDFs with itextsharp. For updating form field names add this code that uses the stamper to change the form field names. /// <summary> /// Merges pdf files from a byte list /// </summary> /// <param name="files">list of files to merge</param> /// <returns>memory stream containing combined pdf<
