Working with Foxit PDF Conversion SDK Node.js API It’s easy to use Foxit PDF Conversion SDK Node.js for converting PDF to Office. We can use PDF paths or PDF streams as a source of PDF input. Before using it, first look at the definition of input parameters. PDFConversionSDK.PDF2Office.StartConvertToWordWithPath(src_pdf_path, src_pdf_password, saved_word_file_path, setting_data, convert_callback); PDFConversionSDK.PDF2Office.StartConvertToPPTWithPath(src_pdf_path, src_pdf_password, saved_ppt_file_path, setting_data, convert_callback); PDFConversionSDK.PDF2Office.StartConvertToExcelWithPath(src_pdf_path, src_pdf_password, saved_excel_file_path, setting_data, convert_callback); PDFConversionSDK.PDF2Office.StartConvertToWordWithStream(src_pdf_reader,src_pdf_password, saved_word_file_stream, setting_data, convert_callback); PDFConversionSDK.PDF2Office.StartConvertToPPTWithStream(src_pdf_reader,src_pdf_password, saved_ppt_file_stream, setting_data, convert_callback); PDFConversionSDK.PDF2Office.StartConvertToExcelWithStream(src_pdf_reader,src_pdf_password, saved_excel_file_stream, setting_data, convert_callback);
This article demonstrates how you can use the select text function with Foxit PDF SDK to activate a web browser translation plugin. In this example, we will use the Chrome Saladict plugin to implement a pop-up dictionary or page translator. We use Foxit PDF SDK to do it and you can get a free 30 day trial here. Platform: Web Programming Language: JavaScript License Key Requirement: Standard SDK Version: Foxit PDF SDK 9.0 Step 1 The first step is to enable the Saladict plugin in the Chrome://extensions panel.
This article aims to demonstrate how to identify a PDF using Layout Recognition. The data structure parsed by Layout Recognition is a bit like a tree structure, the root node is class LRStructureElement. Generally, class LRStructureElement has many child nodes, including class LRGraphicsObjectElement, class LRContentElement or class LRStructureElement. LRContentElement may have a corresponding LRGraphicsObjectElement,, whereas LRGraphicsObjectElement generally does not contain child nodes.
This article will demonstrate creating a custom screenshot tool with Foxit PDF SDK for Web. You can get a free 30 day trial here. Platform: Web Programming Language: JavaScript License Key Requirement: Standard SDK Version: Foxit PDF SDK 9.0 Step 1: Create a customized screenshot image storage service to upload the snapshots. //Custom screenshot image storage service const SnapshotServer = PDFViewCtrl.SnapshotServer; const pdfui = new PDFUI({ ... viewerOptions: { snapshotServer: new SnapshotServer({ origin: location.origin, uploadSnapshotAPIPath: 'snapshot/upload', payloadFieldName: 'file', method: 'POST', render: function(resp) { return resp; } }) ... } }) var pdfviewer = await pdfui.getPDFViewer(); // Capture the picture of the specified area on the page. var imageBlob = await pdfviewer.takeSnapshot(0, 0, 0, 200, 200); // Upload images to a specified server. var uploadResult = await pdfviewer.uploadImage(imageBlob); // Capture the picture and copy it to the clipboard var copyResult = await pdfviewer.copySnapshot(uploadResult);
This article aims to demonstrate how to set annotation flags for different users with our Web SDK. Follow the two steps below to perform the function. We use Foxit PDF SDK to do it and you can get a free 30 day trial here. Platform: Web Programming Language: JavaScript License Key Requirement: Standard SDK Version: Foxit PDF SDK 8.3 Step 1: Set annotation flags to lock annotations of other users at the application level:
This article contains sample code that enables you to create a table of contents based on bookmark Information in PDFs. We use Foxit PDF SDK to do it and you can get a free 30 day trial here. Platform: Windows, Mac, Linux Programming Language: C++, Java, C#, Objective-C, C License Key requirement: StandardC++ void AddTOCToPDF(PDFDoc doc) { //Set the table of contents configuration. Int32Array intarray; int depth = doc.GetBookmarkLevelDepth(); if (depth > 0) { for (int i = 1; i <= depth; i++) { intarray.Add(i); } } WString title = L""; TableOfContentsConfig toc_config = TableOfContentsConfig(title, intarray, true, false); //Add the table of contents doc.AddTableOfContents(toc_config); }
This article demonstrates how to use JavaScript for annotations so you can get the most out of Foxit PDF SDK. Read on below for the 4 simple steps to get started. Platform: Windows, Mac, Linux Programming Language: C++, Java, C#, Objective-C, C License Key requirement: Standard SDK Version: Foxit PDF SDK 8.3 Step 1 LaunchURL: We will start by adding a link annotation to trigger the “launchURL” JavaScript to launch “https://webviewer-demo.foxit.com”
JavaScript is crucial to form workflows for companies who want to boast the latest and greatest in document technologies. The article below demonstrates how to add JavaScript to PDF forms with Foxit PDF SDK. Platform: Windows, Mac, Linux Programming Language: C++, Java, C#, Objective-C, C License Key requirement: Standard SDK Version: Foxit PDF SDK 8.3 Below we will detail six simple demos. Step 1 AFSimple_Calculate: We will add two text field whose values will be used to add together. The third text field will contain the value of the sum of the first two form fields.
Foxit’s advanced forms consist of Ultraforms that render a 2D barcode inside a PDF fillable form. It does this using JavaScript libraries which makes it unique relative to alternative 2D barcode solutions on the market. By comparison, other providers render a 2D barcode inside a PDF fillable form by using the PDF reader application to produce the 2D barcode. This means that they can only render a 2D barcode in a PDF form so long as the form user is using their product. Ultraforms will render a 2D barcode inside a PDF form using any PDF reader product, so long as it has implemented support for the JavaScript specification for PDF. Foxit PDF SDK for Web now adds a fantastic addition because it means form users don’t have to install a PDF reader on their device anymore.
How to trigger JavaScript //JsActionCallback is the implementation class of ActionCallback. JsActionCallback* action_handler = new JsActionCallback(); Library::SetActionCallback(action_handler); Form form(pdf_doc); PDFPage pdf_page = pdf_doc.GetPage(0); //Set JavaScript for the button.
