A font can be embedded only if it contains a setting by the font vendor that permits it to be embedded. Embedding prevents font substitution. When a font cannot be embedded because of the font vendor's settings, and someone who opens or prints a PDF does not have access to the original font.

The basic types of content in a PDF are:. The three views are i the physical view, ii the tags view, and iii the content view. Meet the people who make fonts. The characters are specified using the encoding of a selected font resource. Web Accessibility Center.

Those groupings reflect logical relationships among objects that are meaningful when editing those objects, but they are not part of the imaging model. PDF files may contain interactive elements such as annotations, form fields, video, 3D and rich media. Both formats today coexist in PDF specification: AcroForms were introduced in the PDF 1. AcroForms permit using objects e. Alongside the standard PDF action types, interactive forms AcroForms support submitting, resetting, and importing data.

The "submit" action transmits the names and values of selected interactive form fields to a specified uniform resource locator URL. AcroForms can keep form field values in external stand-alone files containing key: The Forms Data Format can be used when submitting form data to a server, receiving the response, and incorporating into the interactive form.

It can also be used to export form data to stand-alone files that can be imported back into the corresponding PDF interactive form.

In addition, XFDF does not allow the spawning, or addition, of new pages based on the given data; as can be done when using an FDF file. A "tagged" PDF see clause Technically speaking, tagged PDF is a stylized use of the format that builds on the logical structure framework introduced in PDF 1. Tagged PDF defines a set of standard structure types and attributes that allow page content text, graphics, and images to be extracted and reused for other purposes. With the introduction of PDF version, 1.

Layers, or as they are more formally known Optional Content Groups OCGs , refer to sections of content in a PDF document that can be selectively viewed or hidden by document authors or consumers. This capability is useful in CAD drawings, layered artwork, maps, multi-language documents etc. Basically, it consists of an Optional Content Properties Dictionary added to the document root.

This dictionary contains an array of Optional Content Groups OCGs , each describing a set of information and each of which may be individually displayed or suppressed, plus a set of Optional Content Configuration Dictionaries, which give the status Displayed or Suppressed of the given OCGs.

A PDF file may be encrypted for security, or digitally signed for authentication. The standard security provided by Acrobat PDF consists of two different methods and two different passwords: The user password encrypts the file, while the owner password does not, instead relying on client software to respect these restrictions. An owner password can easily be removed by software, including some free online services.

Even without removing the password, most freeware or open source PDF readers ignore the permission "protections" and allow the user to print or make copy of excerpts of the text as if the document were not limited by password protection. There are a number of commercial solutions that offer more robust means of information rights management. Not only can they restrict document access but they also reliably enforce permissions in ways that the standard security handler does not.

The signature is used to validate that the permissions have been granted by a bona fide granting authority.

For example, it can be used to allow a user: For example, Adobe Systems grants permissions to enable additional features in Adobe Reader, using public-key cryptography. Adobe Reader verifies that the signature uses a certificate from an Adobe-authorized certificate authority.

Any PDF application can use this same mechanism for its own purposes. PDF files can have file attachments which processors may access and open or save to a local filesystem. PDF files can contain two types of metadata. This is stored in the optional Info trailer of the file. A small set of fields is defined, and can be extended with additional text values if required. This method is deprecated in PDF 2. This allows metadata to be attached to any stream in the document, such as information about embedded illustrations, as well as the whole document attaching to the document catalog , using an extensible schema.

PDFs may be encrypted so that a password is needed to view or edit the contents. PDF 2. PDF files may also contain embedded DRM restrictions that provide further controls that limit copying, editing or printing. These restrictions depend on the reader software to obey them, so the security they provide is limited. PDF documents can contain display settings, including the page display layout and zoom level. Adobe Reader uses these settings to override the user's default settings when opening the document.

Anyone may create applications that can 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 wrong type of fonts in PDF

PDF files can be created specifically to be accessible for disabled people. Some software can automatically produce tagged PDFs, but this feature is not always enabled by default. Adding tags to older PDFs and those that are generated from scanned documents can present some challenges.

One of the significant challenges with PDF accessibility is that PDF documents have three distinct views, which, depending on the document's creation, can be inconsistent with each other. The three views are i the physical view, ii the tags view, and iii the content view.

The physical view is displayed and printed what most people consider a PDF document. The tags view is what screen readers and other assistive technologies use to deliver a high-quality navigation and reading experience to users with disabilities.

The content view is based on the physical order of objects within the PDF's content stream and may be displayed by software that does not fully support the tags view, such as the Reflow feature in Adobe's Reader. PDF attachments carrying viruses were first discovered in It was activated with Adobe Acrobat, but not with Acrobat Reader. From time to time, new vulnerabilities are discovered in various versions of Adobe Reader, [56] prompting the company to issue security fixes.

Other PDF readers are also susceptible. One aggravating factor is that a PDF reader can be configured to start automatically if a web page has an embedded PDF file, providing a vector for attack. If a malicious web page contains an infected PDF file that takes advantage of a vulnerability in the PDF reader, the system may be compromised even if the browser is secure.

Disabling JavaScript execution in the PDF reader can help mitigate such future exploits, although it does not protect against exploits in other parts of the PDF viewing software. Security experts say that JavaScript is not essential for a PDF reader, and that the security benefit that comes from disabling JavaScript outweighs any compatibility issues caused. On March 30, security researcher Didier Stevens reported an Adobe Reader and Foxit Reader exploit that runs a malicious executable if the user allows it to launch when asked.

A PDF file is often a combination of vector graphics , text, and bitmap graphics. The basic types of content in a PDF are:. Two PDF files that look similar on a computer screen may be of very different sizes. For example, a high resolution raster image takes more space than a low resolution one.

Typically higher resolution is needed for printing documents than for displaying them on screen. Other things that may increase the size of a file is embedding full fonts, especially for Asiatic scripts, and storing text as graphics.

PDF viewers are generally provided free of charge, and many versions are available from a variety of sources.

Adobe Acrobat is one example of proprietary software that allows the user to annotate, highlight, and add notes to already created PDF files. Freeware Qiqqa can create an annotation report that summarizes all the annotations and notes one has made across their library of PDFs. There are also web annotation systems that support annotation in pdf and other documents formats.

In cases where PDFs are expected to have all of the functionality of paper documents, ink annotation is required. Examples of PDF software as online services including Scribd for viewing and storing, Pdfvue for online editing, and Thinkfree , Zamzar for conversion.
