问题 I'm trying to get all words and their location coordinates from a PDF file. I've succeeded using the Acrobat API on .NET . Now, I'm trying to get the same result using a free API, such as iTextSharp (the .NET version). I can get the text (line by line) with PRTokeniser , but I have no idea of how to get the coordinates of the line, let alone of each word. 回答1: My account is too new reply to Mark Storer's answer. I wasn't able to directly use the LocationTextExtracationStrategy (I think I must

Right aligning text in PdfPCell

由 和自甴很熟 提交于 2019-11-26 19:06:18
I have a C# application that generates a PDF invoice. In this invoice is a table of items and prices. This is generated using a PdfPTable and PdfPCell s. I want to be able to right-align the price column but I cannot seem to be able to - the text always comes out left-aligned in the cell. Here is my code for creating the table: PdfPTable table = new PdfPTable(2); table.TotalWidth = invoice.PageSize.Width; float[] widths = { invoice.PageSize.Width - 70f, 70f }; table.SetWidths(widths); table.AddCell(new Phrase("Item Name", tableHeadFont)); table.AddCell(new Phrase("Price", tableHeadFont));

问题 I have written an extraction tool using iTextSharp that extracts annotation information from PDF documents. For the highlight annotation, I only get a rectangle for the area on the page which is highlighted. I am aiming for extracting the text that has been highlighted. For that I use `PdfTextExtractor'. Rectangle rect = new Rectangle( pdfArray.GetAsNumber(0).FloatValue, pdfArray.GetAsNumber(1).FloatValue, pdfArray.GetAsNumber(2).FloatValue, pdfArray.GetAsNumber(3).FloatValue); RenderFilter[]

Changing text line spacing

由 我怕爱的太早我们不能终老 提交于 2019-11-26 18:22:53
问题 I'm creating a PDF document consisting of text only, where all the text is the same point size and font family but each character could potentially be a different color. Everything seems to work fine using the code snippet below, but the default space between the lines is slightly greater than I consider ideal. Is there a way to control this? (FYI, type "ColoredText" in the code below merely contains a string and its color. Also, the reason I am treating the newline character separately is

iTextSharp-generated PDFs now cause Save dialog in Adobe Reader X

由 杀马特。学长 韩版系。学妹 提交于 2019-11-26 17:58:42
I have been using iTextSharp to generate PDF documents for over a year. Unfortunately, with the release of Adobe Reader X, my PDFs now cause a "Do you want to Save?" dialog to appear when closing the PDF document. This does not happen with PDFs that are not generated with iTextSharp. It's really annoying for my users who are opening and closing PDF documents all day long. Are there any properties in iTextSharp that I can set to prevent this from happening? If it helps, I am using a PdfReader to read data from an existing PDF document (this original document does not cause the Save dialog to

问题 I'm not sure that this is possible but I figured it would be worth asking. I have figured out how to set the font of a formfield using the pdfstamper and acrofields methods but I would really like to be able to set the font of different parts of the text in the same field. Here's how I'm setting the font of the form fields currently: // Use iTextSharp PDF Reader, to get the fields and send to the //Stamper to set the fields in the document PdfReader pdfReader = new PdfReader(fileName); //
