Product Description
PDF–to most of the world it stands for that rather tiresome format used for documents downloaded from the web. Slow to load and slower to print, hopelessly unsearchable, and all but impossible to cut and paste from, the Portable Document Format doesn’t inspire much affection in the average user. But PDF done right is another story. Those who know the ins and outs of this format know that it can be much more than electronic paper. Flexible, compact, interactive, and even searchable, PDF is the ideal way to present content across multiple platforms.PDF Hacks unveils the true promise of Portable Document Format, going way beyond the usual PDF as paged output mechanism. PDF expert Sid Steward draws from his years of analyzing, extending, authoring, and embellishing PDF documents to present 100 clever hacks–tools, tips, quick-and-dirty or not-so-obvious solutions to common problems.

PDF Hacks will show you how to create PDF documents that are far more powerful than simple representations of paper pages. The hacks in the book cover the full range of PDF functionality, from the simple to the more complex, including generating, manipulating, annotating, and consuming PDF information. You’ll learn how to manage content in PDF, navigate it, and reuse it as necessary. Far more than another guide to Adobe Acrobat, the book covers a variety of readily available tools for generating, deploying, and editing PDF.

The little-known tips and tricks in this book are ideal for anyone who works with PDF on a regular basis, including web developers, pre-press users, forms creators, and those who generate PDF for distribution. Whether you want to fine-tune and debug your existing PDF documents or explore the full potential the format offers, PDF Hacks will turn you into a PDF power user.

About the Author
For over five years, Sid Steward has analyzed, extended, secured, cracked, authored, converted, embellished and consumed PDF. He maintained and created custom software for Thomson Financial’s Investext and then EBSCO. He then worked with SoftLock (d/b/a Digital Goods) to create their proprietary PDF security model and integrate it with their larger digital rights system. This project required pushing the envelope of Acrobat API programming. At the same time, he had been privately working on a semi-automated PDF to HTML conversion workflow. This toolset became the core of his PDF conversion service bureau: Boundless Books, Inc., d/b/a AccessPDF. He also performs PDF “finishing” which includes optimizing PDF file size and adding navigation features.

How to Sign Documents Electronically – No Ink or Paper Required

You are working hard to achieve that perfect paperless office but there are some things that still require paperwork. For instance, you just received a contract via electronic fax that you are supposed to sign and fax it back. Or there’s a PDF / Word document waiting in your email inbox that you need to print on paper, put your handwritten signatures, scan the signed copy and send it back to the client again via email.

That process is both time consuming and forces you to do something that you are trying so hard to avoid (i.e., use paper). So if you are looking to eliminate paper from the loop, here are some software tools, web services and workarounds that will help you capture your signature directly on the electronic file without requiring paper or ink.

How to Digitally Sign Documents

The first step is to create a digital image of your signature – there are multiple ways of doing that:

Option #1. If you have an iPhone, iPod Touch or any touch sensitive mobile device, use an app like “Fountain Pen” or “Sketch Pad” to draw your signature using your fingers and then transfer the image to your computer.

Option #2. If you have don’t have access to a touch phone or a scanner, put your signatures on a white piece of paper and take a photograph of that paper using your digital camera or even the camera of your mobile phone (some tips).

Option #3. Alternatively, you can use any graphics software (like MS Paint), an online image editor (like Splash Up) or even Google Docs (see video) to draw your signature with the mouse pointer. I like the Google Docs options since it creates a transparent stamp of your signature.

Option #4. Go to Live Signature, draw your signature on the screen and click the “Create Signature” button to download your signature as an image.

Now that you have the written signature in image form, the next step involves putting that e-sign image into the document.

If the contract or agreement is in Microsoft Word or any other common editable format, things are pretty easy. Open the document in any Word processing software (or Google Docs) and insert the signature image inline. Save the document as PDF and email it back to the client.

How to Sign a PDF Document

If the initial document is in Adobe PDF format, you need to follow a couple of extra steps because, unless you have a PDF editor like Adobe Acrobat, editing PDF files is not always straight-forward.

Option #1: Convert the PDF document to Word using this free web service, add the image to the Word file (as in the previous example) and export the document as PDF to prevent editing. The PDF to Word service may not always replicate the exact formatting and appearance of the original PDF file but it’s still very close especially in the case of text documents.

To password protect your signed-PDF documents, open the document inside PDF Hammer, add a password restriction and re-export it as PDF.

Option #2: If the PDF document that you have to sign is long or includes complex formatting, conversion may not be the right option for you. In that case, you have two choices:

2 a: PDF X-Change – This is awesome PDF Viewer for Windows that also includes some very useful editing features.

Import the signature image into the Stamps Palette, open the PDF file that you want to sign and use the stamps tool (under Tools -> Comment & Markup) to sign anywhere in the document. You can then export the signed document as PDF and none of the original formatting should be lost.

2 b: OpenOffice Draw – The latest version of OpenOffice 3.1 along with this free Sun Extension can be used as a PDF editor.

Once installed, click the OpenOffice icon on your desktop and open the PDF document – this will auto open in OpenOffice.org Draw. Now choose Insert -> Picture -> From File to insert the signature image anywhere in the PDF file.

The good part about OpenOffice is that it is available for Windows, Mac and Linux platform but there’s no individual install for the Draw module so you’ll have to download the full 150 installer of OpenOffice.org but choose to install only Draw at setup.

Web Apps for Electronic Signature

The options discussed above are handy if you have to sign documents but what if you are on the other side of the fence and need another party to sign your document electronically.

In that case, you should consider using web based signatures services from either EchoSign or Right Signature – they both work on similar lines. You upload a PDF or Word document that needs to signed and also specify the email addresses of people who have to sign that file. The recipients can open the document inside their web browser, add their signature (with the timestamp) and done.

You can then download the signed document on to your own computer. There’s no software to install and no sending fax messages back and forth. Both Echo Sign and Right Signature are paid services but trial users can send up to 5 documents for free.

[*] These electronic signatures should not be confused with Digital Signatures that can only be had from certification authorities such as Verisign. Electronic signatures on documents are also considered legally binding in most countries.
