Indirect objects are numbered with an object number and a generation number and defined between the obj and endobj keywords. An index table, also called the cross-reference table and marked with the xref keyword, follows the main body and gives the byte offset of each indirect object from the start of the file. Beginning with PDF version 1.
This technique reduces the size of files that have large numbers of small indirect objects and is especially useful for Tagged PDF. At the end of a PDF file is a trailer introduced with the trailer keyword.
It contains. There are two layouts to the PDF files: Non-linear PDF files consume less disk space than their linear counterparts, though they are slower to access because portions of the data required to assemble pages of the document are scattered throughout the PDF file. Linear PDF files also called "optimized" or "web optimized" PDF files are constructed in a manner that enables them to be read in a Web browser plugin without waiting for the entire file to download, since they are written to disk in a linear as in page order fashion.
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. 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. Paths can be stroked, filled, 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 be 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. There are seven types of shading pattern of which the simplest are the axial shade Type 2 and radial shade Type 3. The dictionary describes 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. 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.
Text in PDF is represented by text elements in page content streams. A text element specifies that characters 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: Fourteen typefaces, known as the standard 14 fonts , have a special significance in PDF documents:.
These fonts are sometimes called the base fourteen fonts. 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 predefined encodings, including WinAnsi , MacRoman , and a large number of encodings for East Asian languages, and a font can have its own built-in encoding.
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. PDF can specify a predefined encoding to use, the font's built-in encoding or provide a lookup table of differences to a predefined or built-in encoding not recommended with TrueType fonts.
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. In PDF 1. 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. 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 be viewed incorrectly 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. They have since been published. The concept of a transparency group in PDF specification is independent of existing notions of "group" or "layer" in applications such as Adobe Illustrator.
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.
