Although annoying, these issues can usually be easily remedied through replacing the problem EXE file. In some cases, the Windows registry is attempting to load a foxit updater.exe file that no longer exists, therefore we recommend running a registry scan to repair any invalid file path references.

If you've successfully replaced the file in the right location, your issues with foxit updater.exe should be resolved. We recommend running a quick test to confirm that's the case. You can then re-open Foxit Updater to see if the error message is still triggered.

Usually foxit updater.exe errors with Foxit Updater happen during startup or shutdown, while foxit updater.exe related programs are running, or rarely during the OS update sequence. It's important to note when foxit updater.exe issues happen, as it helps troubleshoot Foxit Updater problems (and report to Foxit Corporation).

Foxit PDF SDK provides high-performance libraries to help any software developer add robust PDF functionality to their enterprise, mobile and cloud applications across all platforms (includes Windows, Mac, Linux, Web, Android, iOS, and UWP), using the most popular development languages and environments.

Foxit PDF SDK for Java API ships with simple-to-use APIs that can help Java developers seamlessly integrate powerful PDF technology into their own projects on Windows and Linux platforms. It offers the most common features in PDF SDK, such as PDF viewing, bookmark navigating, text selecting/copying/searching, annotations, and signature.

Foxit PDF SDK allows users to download trial version to evaluate SDK. The trial version has no difference from a standard version except for the 10-day limitation trial period and the trail watermarks that will be generated on the PDF pages. After the evaluation period expires, customers should contact Foxit sales team and purchase licenses to continue using Foxit PDF SDK.

Developers should purchase licenses to use Foxit PDF SDK in their solutions. Licenses grant users permissions to release their applications based on PDF SDK libraries. However, users are prohibited to distribute any documents, sample codes, or source codes in the SDK released package to any third party without the permission from Foxit Software Incorporated.

This guide is intended for developers who need to integrate Foxit PDF SDK for Java into their own applications. It aims at introducing installation package structure on desktop platform with Java, and the usage of SDK.

NOTE: the highlighted rectangle in the figure is just the version of Foxit PDF SDK. Here the SDK version is 6.4, so it shows 6_4 in the package name. Other highlighted rectangles in other figures have the same meaning in this guide.

Note:If you have not installed Eclipse IDE in your machine, you can create a Java file, and then use command line to build and run it. For example, we use the test.java file created in the previous Eclipse IDE, and then follow the steps below:

In this section, we will introduce a set of major features and list some examples for each feature to show you how to integrate powerful PDF capabilities with your applications using Foxit PDF SDK Java API. You can refer to the API reference [2] to get more details about the APIs used in all of the examples.

It is necessary for applications to initialize and unlock Foxit PDF SDK license before calling any APIs. The function Library.initialize is provided to initialize Foxit PDF SDK. A license should be purchased for the application and pass unlock key and code to get proper supports. When there is no need to use Foxit PDF SDK any more, please call function Library.release to release it.

A PDF document object can be constructed with an existing PDF file from file path, memory buffer, a custom implemented ReaderCallback object and an input file stream. Then call function PDFDoc.load or PDFDoc.startLoad to load document content. A PDF document object is used for document level operation, such as opening and closing files, getting page, metadata and etc.

PDF Page is the basic and important component of PDF Document. A PDFPage object is retrieved from a PDF document by function PDFDoc.getPage. Page level APIs provide functions to parse, render, edit (includes creating, deleting and flattening) a page, retrieve PDF annotations, read and set the properties of a page, and etc. For most cases, A PDF page needs to be parsed before it is rendered or processed.

PDF rendering is realized through the Foxit renderer, a graphic engine that is used to render page to a bitmap or platform graphics device. Foxit PDF SDK provides APIs to set rendering options/flags, for example set flag to decide whether to render form fields and signature, whether to draw image anti-aliasing and path anti-aliasing. To do rendering, you can use the following APIs:

To render page and annotations, first use function Renderer.setRenderContentFlags to decide whether to render page and annotation both or not, and then use function Renderer.startRender to do the rendering. Function Renderer.startQuickRender can also be used to render page but only for thumbnail purpose.

In Foxit PDF SDK, attachments are only referred to attachments of documents rather than file attachment annotation, which allows whole files to be encapsulated in a document, much like email attachments. PDF SDK provides applications APIs to access attachments such as loading attachments, getting attachments, inserting/removing attachments, and accessing properties of attachments.

Foxit PDF SDK provides APIs to extract, select, search and retrieve text in PDF documents. PDF text contents are stored in TextPage objects which are related to a specific page. TextPage class can be used to retrieve information about text in a PDF page, such as single character, single word, text content within specified character range or rectangle and so on. It also can be used to construct objects of other text related classes to do more operations for text contents or access specified information from text contents:

In a PDF page, some text contents that represent a hypertext link to a website or a resource on the intent, or an email address are the same with common texts. Prior to text link processing, user should first call PageTextLinks.getTextLink to get a textlink object.

XFA (XML Forms Architecture) forms are XML-based forms, wrapped inside a PDF. The XML Forms Architecture provides a template-based grammar and a set of processing rules that allow uses to build interactive forms. At its simplest, a template-based grammar defines fields in which a user provides data.

Note: Foxit PDF SDK provides two callback classes com.foxit.sdk.addon.xfa.AppProviderCallback and com.foxit.sdk.addon.xfa.DocProviderCallback to represent the callback objects as an XFA document provider and an XFA application provider respectively. All the functions in those classes are used as callback functions. Pure virtual functions should be implemented by users.

Fillable PDF forms (AcroForm) are especially convenient for preparation of various applications, such as taxes and other government forms. Form design provides APIs to add or remove form fields (Acroform) to or from a PDF file. Designing a form from scratch allows developers to create the exact content and layout of the form they want.

2) Foxit SDK supports a customized annotation type called PSI (pressure sensitive ink) annotation that is not described in PDF reference [1]. Usually, PSI is for handwriting features and Foxit SDK treats it as PSI annotation so that it can be handled by other PDF products.

Foxit PDF SDK provides APIs for conversion between PDF files and images. Applications could easily fulfill functionalities like image creation and image conversion which supports the following image formats: BMP, TIFF, PNG, JPX, JPEG, and GIF. Foxit PDF SDK can make the conversion between PDF files and the supported image formats except for GIF. It only supports converting GIF images to PDF files.

Watermark is a type of PDF annotation and is widely used in PDF document. Watermark is a visible embedded overlay on a document consisting of text, a logo, or a copyright notice. The purpose of a watermark is to identify the work and discourage its unauthorized use. Foxit PDF SDK provides APIs to work with watermark, allowing applications to create, insert, release and remove watermarks.

A barcode is an optical machine-readable representation of data relating to the object to which it is attached. Originally barcodes systematically represented data by varying the widths and spacing of parallel lines, and may be referred to as linear or one-dimensional (1D). Later they evolved into rectangles, dots, hexagons and other geometric patterns in two dimensions (2D). Although 2D systems use a variety of symbols, they are generally referred to as barcodes as well. Barcodes originally were scanned by special optical scanners called barcode readers. Later, scanners and interpretive software became available on devices including desktop printers and smartphones. Foxit SDK provides applications to generate a barcode bitmap from a given string. The barcode types that Foxit SDK supports are listed in Table 32.

Foxit PDF SDK provides a range of encryption and decryption functions to meet different levels of document security protection. Users can use regular password encryption and certificate-driven encryption or using their own security handler for custom security implementation. It also provides APIs to integrate with the third-party security mechanism (Microsoft RMS). These APIs allow developers to work with the Microsoft RMS SDK to both encrypt (protect) and decrypt (unprotect) PDF documents.

Pressure Sensitive Ink (PSI) is a technique to obtain varying electrical outputs in response to varying pressure or force applied across a layer of pressure sensitive devices. In PDF, PSI is used for hand written signatures. PSI data are collected by touching screens or handwriting on boards. PSI data contains coordinates and canvas of the operating area which can be used to generate the appearance of PSI. Foxit PDF SDK allows applications to create PSI, access properties, operate on ink and canvas, and release PSI.
