Introduction to PDF Library

Designed specifically for OEMs, ISVs, system integrators, and enterprise IT developers, the PDF Library SDK contains a powerful set of functions for developing third-party solutions and processes around PDF. The PDF Library is based on the core technology of the Acrobat line of products and offers complete functionality for generating, manipulating, rendering, and printing PDF documents.

The library enables PDF functionality to be seamlessly embedded within applications. It also provides reliable, accurate and -supported implementation of the latest PDF specification.

The PDF Library and the PDF viewers

The PDF Library shares much of the same source code as the PDF viewing applications (Acrobat Professional, Acrobat Standard and Reader). There is a large degree of overlap between the functionality provided by the PDF Library Software Development Kit (SDK) and that of the Acrobat SDK. They differ in providing access to the Acrobat user interface:

1. The Acrobat SDK is meant for the plug-in environment, and allows you to control and interact with the Acrobat user interface.
2. The PDF Library SDK is intended for interaction between PDF content and other applications, such as high volume batch processing and PDF generation applications. It does not export methods for creating or managing Acrobat UI elements—that is, the AcroView (AV) layer of the core API.

If you are interested in the documentation and samples in the Acrobat Software Development Kit (SDK), see the Acrobat Developer Center.

About the PDF Library SDK

This helps you get started with development using the PDF Library SDK. It describes the contents of each directory in the SDK installation, lists available code samples, and provides platform-specific information on how to set up the development environment.

PDF Library Supported environments

PDF Library SDK and its project files are supported for the platforms, operating systems, and compilers listed in Developing Plug-ins and Applications. While it may be possible to use the library in other development environments, such use is not supported by Developer Support.

The PDF Library SDK consists of the following components:

1. CorePDF libraries that provide the functionality
2. Header files that provide access to the libraries
3. Sample applications and code snippets showing how to use the library for a variety of purposes
4. Documentation of installation and development techniques and of the PDF Library APIs

The components that are shipped with the PDF Library SDK are listed in Developing Plug-ins and Applications. These include the PDF Library, helper libraries, headers, and samples.

Installing the PDF Library SDK

The PDF Library SDK installation process differs depending on the target platform

1. Windows — Do one of the following:
2. For the standard version of the PDF Library SDK, unzip PDFLibrarySDKMinSize18.x.y.zip
3. For the speed-optimized version of the PDF Library SDK, unzip PDFLibrarySDKMaxSpeed18.x.y.zip.
4. Mac OS — Mount the dmg image, PDFLibrarySDK18.x.y.dmg, and copy the PDFLibrarySDK18.x.y folder to your local drive.
5. Linux — A gzip compressed tar file, PDFLibrarySDK18.x.y.tar.gz, is provided; developers determine where to decompress and install the SDK

Updating to PDF Library SDK

All PDF Library SDK APIs are still supported in PDF Library SDK . Other than a few minor code changes, all you should need to do is recompile your application with the new SDK headers using the recommended development environment.

Windows PDF Library

If applicable, change PDFLibrary70.lib to PDFLibrary.lib in your project settings. By default, for 18.x builds, Windows SDK version for all samples and plugins is set to 10.0.15063.0 which is included in Visual Studio 2017 version 15.1.

Mac OS PDF Library

Refer to the sample projects for information on updating. PDF Library SDK uses frameworks instead of shared libraries. For convenience, the sample applications are built to include the PDF Library frameworks. The libraries are in the Libs:Mac:PDFLibrary.framework folder. Aliases or proper paths need to be set to ensure that your applications run properly. Include PDFLibraryInitCommon.c in the Include:Headers folder to your client project. All C source files must be compiled as C++ files using the following steps: 1. In the project source pane, select the file(s) and click Get Info. 2. In the General panel, change the File Type: popup from sourcecode.c.c to sourcecode.cpp.cpp. The Needs Raise Aware flag has been turned off on Mac OS.

Linux PDF Library

Before you can build your product on a Linux platform running the CentOS 7.3 operation system, you must procure the Clang compiler. We recommend using version 3.9.1 or later, and keeping the compiler in the directory: /opt/llvm/ Update your makefile to reflect any new libraries in the libs folder. Important – For linux platform, new libraries libc++, libc++abi and libunwind are now included along with the existing libraries libgcc and libstdc++ in the packaging and makefiles for samples has been updated for the same. These libraries are released in PDFLibrarySDK18.x.y/Libs/linux_64/ folder. Note: Regular support for Linux-32 bit has been withdrawn.

How to Open PDF Files

PDF (Portable Document Format) files are widely used to create and share documents, as the PDF will keep formatting intact regardless of the viewer's operating system and software. Because it is a different kind of document file, it requires special software in order to open. Nearly every device will be able to open and view PDFs with the right software.

Windows PDF Files

Download Adobe Reader. This is a free program that can open PDF files so that you can read them. Adobe Reader can be downloaded from get.adobe.com/reader/. You cannot use it to edit or create PDF files.

To learn how to edit PDF files, you can edit PDF files online.

There are a variety of other free PDF reader programs if you don't want to install Adobe Reader. Windows 8 comes with a PDF reader installed if you don't want to use Adobe Reader.

Mac PDF Files

Double-click the PDF. OS X comes with Preview, a tool that opens a wide variety of files, including PDF files. Preview allows you to read PDF files, but not edit them. To learn how to edit PDF files.

Change the program that OS X uses to open PDFs. If you have a different PDF program and no longer want to use Preview, you can set all PDF files to open with the new program.

PDFs won't open in Safari. This is typically caused by an error with the Adobe plugin after updating Safari. You can fix it by manually deleting the plugin and restarting Safari.[2] Open /Library/Internet Plugins/ and delete AdobePDF.plugin Open /User/Username/Library/Internet Plugins/ and delete AdobePDF.plugin Restart Safari and try to open the PDF again.

"Adobe could not open PDF name because...". This error typically occurs if you save a PDF file using Safari's "Save As" or "PDF Export" option. Reopen the PDF in Safari. Click the Disk (Save) button at the top of the window or in the from the menu that appears when you move your mouse to the bottom-center of the page. Save the PDF file to your computer. Open the newly-saved file.

Android PDF Files

Download an app that supports PDF files. While Android does not have "built-in" support for reading PDF files, there are a large number of free apps that will easily open your PDF files. You may even have one of these already installed: Google Drive Quickoffice Adobe Reader Foxit MobilePDF

Find the PDF file you want to open. Typically, when you download a PDF file, you can open it from your Notification bar by tapping the completed download. If you need to open the PDF file later, you can do so from your Downloads folder.

PDF attempts to open in the wrong app. if your PDF is trying to open in an app that doesn't support PDFs, you may have the default app set wrong.

Tap the PDF that you want to open. iOS has a built-in PDF reader which can be used to open PDF attachments in emails or PDFs that you find online.

Tap the open PDF to open the menu. This will allow you to select another app to handle the PDF.

Tap "Open in..." or the Share button. If you are viewing the PDF in your Mail app, you will use the Share button. If you are viewing the PDF in Safari, you will use the "Open in..." button. This will display a list of apps that support PDF.

Select the app that you want to use. You can add your PDF files to iBooks, or open it in Adobe Reader or any other PDF application you have installed on your iOS device. The PDF will open immediately in your selected app.[4]

How to Edit a PDF Without Adobe Acrobat?

We've outlined the best PDF editor apps— and Google Drive isn't one of them. For filling in forms and editing layout, you might want to download your PDF from Drive and use one of those apps. But Google Drive can work in a pinch.

Google Drive makes it easy to convert any PDF into a Google Doc, and and the built-in optical character recognition (OCR) will even extract text from images.Here's how to get started.

Preview Any PDF in Google Drive

Open drive.google.com in your browser. You can click-and-drag the PDF from your file browser, or you can click New followed by File Upload and browse to the file you want to upload.

You can read the entire PDF from here. The downside: You can't make any edits or even fill out fillable forms. You also can't copy text that was scanned into a PDF.

Convert a PDF File to a Google Doc

Google Drive can automatically transform any PDF into a Google Doc, allowing you to edit the text as you will. Even text in images will transfer over to this document, thanks to Drive's built in OCR capability.

Google Drive will now smack your PDF with an ugly stick, removing all images and generally ruining the layout. Still, this is a very quick way to extract the text from a PDF. And the built-in OCR support means you can use this method to convert a series of scanned images into text in just a couple of clicks.

Open PDF Files Using Third-Party Readers

Google Drive doesn't offer any PDF editing, meaning you can't do things like fill out forms or change a PDF's layout. You can preview a PDF, you can convert a PDF to a Docs file, and that's about it. There are third-party apps you can connect with Google Drive for editing PDF files. To get started, open a PDF, then click Open With > Connect More Apps.
