![]() Open the result for demonstration purposes. Place the Shape into top-left corner (0 mm, 0 mm) of page. Create a new invisible Shape for the digital signature. String loadPath = savePath = "Result.pdf" ĭocumentCore dc = DocumentCore.Load(loadPath) / Load an existing document (*.docx, *.rtf, *.pdf, *.html, *.txt, *.pdf) and save it in a PDF document with the digital signature. = signaturePict Īs the result, you will get the digitally signed ![]() Visual representation of digital signature. = Placeholder where signature should be visualized. ![]() Additional information about the certificate. The reason is to prevent unauthorized the using of the certificate. Each certificate is protected by a password. PdfSaveOptions options = new PdfSaveOptions() New Size(20, 10, LengthUnit.Millimeter)) Īnd the last step is to point of a certificate (*.pfx) and its characteristics: Password of the certificate, New VerticalPosition(14.5, LengthUnit.Centimeter, VerticalPositionAnchor.Page), After as shown into the image and type in search box 'Aspose.PDF'. Aspose.PDF is a standalone API and it does not depend on any software including Adobe Acrobat. One can create, modify, compress, secure, print or save PDF to TXT, HTML, PCL, XFA, XML, XPS, EPUB, TEX, Images and more formats. Here are the steps: Right click on Solution ,find Manage NuGet Package manager and click on it. Aspose.PDF API can be used for PDF document manipulation and parsing within applications. Now the next step is to add the reference of Aspose.PDF APIs into our created MVC Project. New HorizontalPosition(4.5, LengthUnit.Centimeter, HorizontalPositionAnchor.Page), Step 2 : Add The Reference of Aspose.PDF into project. Picture signaturePict = new Picture(dc, Signature picture will be positioned: Picture which symbolizes a handwritten signature. ![]() Paragraph firstPar = dc.GetChildElements(true).OfType().FirstOrDefault() Īdd a handwritten picture for our digital signature and specify the position on the page: Find a first paragraph and insert our Shape inside it. ((FloatingLayout)signatureShape.Layout).WrappingStyle = WrappingStyle.InFrontOfText New VerticalPosition(0f, LengthUnit.Millimeter, VerticalPositionAnchor.TopMargin), new Size(1, 1))) Shape signatureShape = new Shape(dc, Layout.Floating(new HorizontalPosition(0f, LengthUnit.Millimeter, HorizontalPositionAnchor.LeftMargin), Place the Shape into top-left corner (0 mm, 0 mm) of ![]() Sign Pdf document with customized appearance of digital signature. String loadPath = a new invisible Shape for the digital signature. Analyze SignResult result to check newly created signatures if needed. Once the object of a particular signature type is created, you can use the Sign method of the PdfFileSignature class to sign the PDF and pass the particular signature object to this class. Develop & deploy on Windows, Linux, MacOS & Android platforms. In order to create a signature of a specific type, you need to create an object of the particular class like PKCS1, PKCS7 or PKCS7Detached using the certificate file and the password. Class Libraries & REST APIs for the developers to manipulate & process Files from Word, Excel, PowerPoint, Visio, PDF, CAD & several other categories in Web, Desktop or Mobile apps. Curl - X POST "" - H "accept: application/json" - H "Content-Type: application/json" - d "" - H "authorization: Bearer of all, you need to point an existing document (*.docx, *.rtf, *.pdf, *.html, *.txt, etc) which you also provides different kinds of signatures like PKCS1, PKCS7, and PKCS7Detached. ![]()
