问题 I want to resize a pdf to a specific size, but when I use scaling it loses accuracy because a float rounds the value. Is there a way that I can resize a pdf with a given width and height? This is what I've tried so far: public void PDFScalingTest11(string FileIn, string FileOut) { // The following code opens a pdf and place it 20 times on a new pdf page // I want to resize the pdf before adding it int iQuantity = 20; int iCol = 3; int iRow = 0; float fTileSpacing = 0; float fPrintWidth =

How to avoid bcprov-jdk16-1.45.jar while running the application through POM entry

由 只愿长相守 提交于 2021-01-28 10:58:36
问题 I have a Java 8 application running in Weblogic 12.1.3. The application uses iText 5.5.9 and minimum version of BC required is 1.49 . The application is deploying as a WAR file in Weblogic . I could see the war file is having the proper version of BC . But during run time its taking from WebLogic maven plugin path and using BC 1.45. Is there any way we can avoid this by editing POM entry or by editing WebLogic.xml . If i remove BC 1.45 jar from my local server its running successfully. But i

iText7: How to get the real width of a Paragraph

由 为君一笑 提交于 2021-01-28 09:13:57
问题 I need to know the width (in point) of a Paragraph before add to the document. I searched here and found Alexey answer about Paragraph's height. So I made it with width, but it doesn't work. Always return the Rectangle's width no matter how long the Paragraph. I tried this code: private float getRealParagraphWidth(Document doc, Paragraph paragraph) { // Create renderer tree IRenderer paragraphRenderer = paragraph.createRendererSubTree(); // Do not forget setParent(). Set the dimensions of the

问题 I try to sign a pdf file using my smartcard (USB token) but encounter "Document has been altered or corrupted since it was signed" error when I open the signed pdf file in Adobe. The error is not so descriptive and I'm not sure where to look at because the code seems good to me but apparently it's not.. The code that I use is: var signer = smartCardManager.getSigner("myTokenPassword"); var toBeSignedHash = GetHashOfPdf(File.ReadAllBytes(@"xxx\pdf.pdf"), cert.asX509Certificate2().RawData, "dsa

iText 7 - HTML to PDF write to MemoryStream instead of file

由 风流意气都作罢 提交于 2021-01-24 09:26:12
问题 I'm using iText 7, specifically the HtmlConverter.ConvertToDocument method, to convert HTML to PDF. The problem is, I would really rather not create a PDF file on my server, I'd rather do everything in memory and just send it to the users browser so they can download it. Could anyone show me an example of how to use this library but instead of writing to file write to a MemoryStream so I can send it directly to the browser? I've been looking for examples and all I can seem to find are those

在linux环境下使用itext生成pdf
