I googled "pdf convert" and found you... on the top "organic search" lineI needed to publish my resume & some of my company brochures into PDF format for a government online sales proposal. I was so baffled I finally googled "pdf convert" and found you... on the top "organic search" line! My .pdf's forwarded flawlessly through both gmail and my disposable email service. Sweet (FREE) DEAL!

[PDF Online] makes it much easier than trying to use a softwareI am very impressed with the quality of your pdf conversions. I use if for my MS Publisher newsletter for my church group. It makes it much easier than trying to use a software that everyone has. I have told many of my friends about your site.

My experience with PDFonline has been crucial to the success of my academia, career search, and business. Every PC user should use this service should they need to submit a document on a Unix system or if they do not have the full Adobe Acrobat to convert their files. I have used the conversion utility at PDFonline to obtain .pdf versions for many assignments and resumes. If I am on the road at a remote location, I can always count on PDFonline to return my documents in .pdf form for either a client, a website, or a friend. I thank PDFonline not only for helping me but for all the others that have forgotten to drop them a letter of appreciation.

Convert documents to PDF
Easily create Adobe PDF documents that preserve the formatting and integrity of the original file

PDF was invented by Adobe in 1990 and has steadily grown into the de facto standard for trusted electronic documents and forms. In the course of normal business, you probably encounter PDF documents on a daily basis — for example, whenever you need to share critical information with colleagues or clients, but you don't want to share the native file. Or whenever you need to protect a file so that others cannot change it.

With Adobe® Acrobat® 8 Professional software, you can easily convert and optimize documents, spreadsheets, e-mails, websites, technical drawings, and 3D designs into more secure Adobe PDF files.

Google Moves Toward Adobe Flex
The SearchMash Web site has a new look

adobe flex
This Web site is operated by Google. Just enter the word(s) and the search begins. Let’s do it together. Type Leonard Cohen and press Enter. It’ll bring you to a page with the relevant links to this great Canadian song writer and singer.

Click on the tab Video, and you’ll see a number of Cohen’s videos without any Web page refreshes. Move the mouse over these thumbnail images, read the tooltips and find the song “Dance me to the end of love.” Click on it, and you’ll see a YouTube player on the right (no page refreshes). Put on your head phones and enjoy. If you haven’t heard his music yet I envy you, cause I already did.

So why this new Google Web site important? You may not know, but for many years Google was a three-language company: Java, C++ and Python. The fact that they are starting to use Flex is important not because it’s more proof that Flex is a solid technology for RIA, yada, yada, yada. What’s really important is that this can serve as a signal to a myriad of small software vendors that will now be inspired to work on what will possibly become the next killer application in Flex and maybe, just maybe, will get these small vendors on Google’s radar.

About Yakov FainYakov Fain is a managing principal of Farata Systems, consulting, training and product company. He's authored several Java books, dozens of technical articles. SYS-CON Books has released his latest book, "Rich Internet Applications with Adobe Flex and Java: Secrets of the Masters" in Spring of 2007. Sun Microsystems has nominated and awarded Yakov with the title Java Champion. He leads the Princeton Java Users Group. Yakov teaches Java and Flex 2 part time at New York University. He is an Adobe Certified Flex Instructor

PDF Spam Back With a Vengeance

Because of the malware now hidden in the attachment, this round of PDF spam is significantly more malicious than the flood that hit in August.
Cara Garretson, Network World

PDF spam, the summertime nuisance that flooded inboxes in early August and then quickly disappeared, is back and worse than ever.

According to multiple threat researchers at security vendors, tens of thousands of spam messages were blasted out last week with attached PDF files, which infect the recipients' PCs when viewed. The subject lines of the new crop of PDF spam are finance-related, according to security vendors, using phrases designed to get the recipient's attention such as "your credit report." These e-mails contain no text, simply the attachment.

"When opened, the PDF file uses the CVE-2007-5020 vulnerability via Acrobat Reader and [Internet Explorer 7.0] and downloads further malware from a server in Malaysia," according to security vendor F-Secure's recent blog post. "The target of the malware seems to be to create a botnet of infected machines to be used for further malicious activity."

This summer's PDF spam raised eyebrows because of the sheer volume of the messages and the creative thinking on the part of spammers who figured out these messages could circumvent most antispam filters because they're not trained to read PDF attachments.

Because of the malware now hidden in the attachment, this round of PDF spam is significantly more malicious than August's blasts that were typically pump-and-dump stock messages.

The PDFs attached to those messages hid no malware, but attempted to persuade recipients to buy penny stocks in a little-known company so the stock price would be driven up and the spammer could sell at a profit.

While PDF spam disappeared by September as quickly as it arrived -- it went from 30% of all spam sent on Aug. 7 to less than 1% on Aug. 29 -- few security professionals are expressing surprise at its return.

Spammers will "exploit any vulnerabilities they can, which in Windows is about a quadrillion different places," says John Levine [stet], president of consulting firm Taughannock Networks and co-chair of the Internet Engineering Task Force's Anti-Spam Research Group, adding that he believes this PDF spam blast to be the latest incarnation of the Storm malware. "Using Acrobat has the added advantage that it works regardless of what mail program you use, so even people who use Eudora or Thunderbird could get bitten."

Adobe on Oct. 22 released a security update for versions 8.1 and earlier of Adobe Reader and Acrobat

pdf portable document format

pdf portable document format

From Wikipedia, the free encyclopedia

Portable Document Format (PDF)

"PDF" redirects here. For other uses, see PDF (disambiguation).

The Portable Document Format (PDF) is the file format created by Adobe Systems in 1993 for document exchange. PDF is used for representing two-dimensional documents in a device-independent and display resolution-independent fixed-layout document format. Each PDF file encapsulates a complete description of a 2-D document (and, with Acrobat 3-D, embedded 3-D documents) that includes the text, fonts, images, and 2-D vector graphics that compose the document.

PDF is an open standard, and is now being prepared for submission as an ISO standard

When the PDF first came out in the early 1990s, its general adoption was slow. At that time, the PDF-creation tools (Acrobat) and the viewing and printing software had to be bought. Early versions of PDF had no support for external hyperlinks, reducing its usefulness on the World Wide Web; the additional size of the PDF document compared to plain text meant significantly longer download times over the slower modems common at the time, and rendering the files was slow on less powerful machines. Additionally, there were competing formats such as Envoy, Common Ground Digital Paper and even Adobe's own PostScript format (.ps); in those early years, the PDF file was mainly popular in desktop publishing workflow.

Adobe soon started distribution at no cost of the Acrobat Reader (now Adobe Reader) program, and continued supporting the original PDF, which eventually became the de facto standard for printable documents.

The PDF file format has changed several times, as new versions of Adobe Acrobat have been released. There have been eight versions of PDF: 1.0 (1993), 1.1 (1994), 1.2 (1996), 1.3 (1999), 1.4 (2001), 1.5 (2003), 1.6 (2005), and 1.7 (2006), corresponding to Acrobat releases 1.0 to 8.0.

See also History of PDF Openness

Technical Foundations
Anyone may create applications that read and write PDF files without having to pay royalties to Adobe Systems; Adobe holds patents to PDF, but licenses them for royalty-free use in developing software complying with its PDF specification.

The PDF combines three technologies:

A sub-set of the PostScript page description programming language, for generating the layout and graphics.
A font-embedding/replacement system to allow fonts to travel with the documents.
A structured storage system to bundle these elements and any associated content into a single file, with data compression where appropriate.

PostScript is a page description language run in an interpreter to generate an image, a process requiring many resources. PDF is a file format, not a programming language, i.e. flow control commands such as if and loop are removed, while graphics commands such as lineto remain.

Often, the PostScript-like PDF code is generated from a source PostScript file. The graphics commands that are output by the PostScript code are collected and tokenized; any files, graphics, or fonts to which the document refers also are collected; then, everything is compressed to a single file. Therefore, the entire PostScript world (fonts, layout, measurements) remains intact.

As a document format, PDF has several advantages over PostScript:

PDF contains already tokenized and interpreted results of the PostScript source code, for direct correspondence between changes to items in the PDF page description and changes to the resulting page appearance.

PDF (from version 1.4) supports true graphic transparency, PostScript does not.
PostScript is an imperative programming language (with an implicit global state), so instructions accompanying the description of one page can affect the appearance of any following page. Therefore, all preceding pages must be processed in order to determine the correct appearance of a given page; each page in a PDF document is unaffected by the others.

Technical Overview
File Structure

A PDF file consists primarily of objects, of which there are eight types:[4]
Boolean values, representing true or false
Arrays, ordered collections of objects
Dictionaries, collections of objects indexed by Names
Streams, usually containg large amounts of data.
The null object

Objects may be either direct (embedded in another object) or indirect. Indirect objects are numbered with an object number and a generation number. An index table called the xref table gives the byte offset of each indirect object from the start of the file.[5] This design allows for efficient random access to the objects in the file, and also allows for small changes to be made without rewriting the entire file (incremental update).

Beginning with PDF version 1.5, indirect objects may also be located in special streams known as object streams. This technique reduces the size of files that have large numbers of small indirect objects and is especially useful for Tagged PDF.

Imaging Model
The basic design of how graphics are represented in PDF is very similar to that of PostScript, except for the use of transparency, which was added in PDF 1.4.
PDF graphics use a device independent Cartesian coordinate system to describe the surface of a page. A PDF page description can use a matrix to scale, rotate, or skew graphical elements. A key concept in PDF is that of the graphics state, which is a collection of graphical parameters that may be changed, saved, and restored by a page description. PDF has (as of version 1.6) 24 graphics state properties, of which some of the most important are:

The current transformation matrix (CTM) which determines the coordinate system
The clipping path
The color space
The alpha constant which is a key component of transparency

Vector Graphics
Vector graphics in PDF, as in PostScript, are constructed with paths. Paths are usually made from of lines and cubic Bezier curves, but can also be constructed from the outlines of text. Unlike PostScript, PDF does not allow a single path to mix text outlines with lines and curves. Paths can be stroked, filled, or used for clipping. Strokes and fills can use any color set in the graphics state, including patterns.

PDF supports several types of patterns. The simplest is the tiling pattern in which a piece of artwork is specified to be drawn repeatedly. This may a colored tiling pattern, with the colors specified in the pattern object, or an uncolored tiling pattern, which defers color specification to the time the pattern is drawn. Beginning with PDF 1.4 there is also a shading pattern which draws continuously varying colors. There are seven types of shading pattern of which the simplest are the radial shade (Type 2) and axial shade (Type 3).

Raster Images
Raster images in PDF (called Image XObjects) are represented by dictionaries with an associated stream. The dictionary described properties of the image, and the stream contains the image data. (Less commonly, a raster image may be embedded directly in a page description as an inline image.) Images are typically filtered for compression purposes. Image filters supported in PDF include the general purpose filters

ASCII85Decode a deprecated filter used to put the stream into 7-bit ASCII
ASCIIHexDecode similar to ASCII85Decode but less compact
FlateDecode a commonly used filter based on the DEFLATE or Zip algorithm
LZWDecode a deprecated filter based on LZW Compression
RunLengthDecode a simple compression method for streams with repetitive data using the Run-length encoding algorithm
and the image-specific filters

Normally all image content in a PDF is embedded in the file. But PDF allows image data to be stored in external files by the use of external streams or Alternate Images. Standardized subsets of PDF, including PDF/A and PDF/X, prohibit these techniques.

Text in PDF is represented by text elements in page content streams. A text element specifies that characters in should be drawn at certain positions. The characters are specified using the encoding of a selected font resource.

A font object in PDF is a description of a digital typeface. It may either describe the characteristics of a typeface, or it may include an embedded font file. The latter case is called an embedded font while the former is called an unembedded font. The font files that may be embedded are based on widely used standard digital font formats: Type 1 (and its compressed variant CFF), TrueType, and (beginning with PDF 1.6) OpenType. Additionally PDF supports the Type 3 variant in which the components of the font are described by PDF graphic operators.

Within text strings characters are shown using character codes (integers) that map to glyphs in the current font using an encoding. There are a number of built-in encodings, including WinAnsi, MacRoman, and a large number of encodings for East Asian languages. (Although the WinAnsi and MacRoman encodings are derived from the historical properties of the Windows and Macintosh operating systems, fonts using these encodings work equally well on any platform.) The encoding mechanisms in PDF were designed for Type 1 fonts, and the rules for applying them to TrueType fonts are complex.
For large fonts or fonts with non-standard glyphs, the special encodings Identity-H (for horizontal writing) and Identity-V (for vertical) are used. With such fonts it is necessary to provide a ToUnicode table if semantic information about the characters is to be preserved.

The original imaging model of PDF was, like PostScript's, opaque: each object drawn on the page completely replaced anything previously marked in the same location. In PDF 1.4 the imaging model was extended to allow transparency. When transparency is used, new objects interact with previously marked objects to produce blending effects. The addition of transparency to PDF was done by means of new extensions that were designed to be ignored in products written to the PDF 1.3 and earlier specifications. As a result, files that use a small amount of transparency might view acceptably in older viewers, but files making extensive use of transparency could view completely wrong in an older viewer without warning.
The transparency extensions are based on the key concepts of transparency groups, blending modes, shape, and alpha. The model is closely aligned with the features of Adobe Illustrator version 9. The blend modes were based on those used by Adobe Photoshop at the time. When the PDF 1.4 specification was published the formulas for calculating blend modes were kept secret by Adobe. They have since been published.[6]
