Indirect ObjectsĪny object in a PDF file may be labelled as an indirect object.Do not alter the sections as Oracle Reports parses the uifont.ali file looking for keywords. There can be other other objects like comments which are introduced with the % sign and may contain 8-bit characters.

Streams - represents sequence of bytes which can be of unlimited length as well.

Dictionaries - collection of objects as key-value pairs.

Arrays of higher dimensions can be constructed by using arrays as nested elements

Arrays - PDF supports one dimensional arrays.

ASomewhatLongerName results in ASomewhatLongerName

Names - start with a forward / character e.g.

Strings - contains characters within parentheses.

Boolean values - representing conditional true or false.

PDF ObjectsĪ PDF file includes several different type of objects that are of following types The two preceding lines shall contain, one per line and in order, the keyword startxref and the byte offset in the decoded stream from the beginning of the file to the beginning of the xref keyword in the last cross-reference section. The last line of the file shall contain only the end-of-file marker, %%EOF. Conforming readers should read a PDF file from its end.

The trailer of a PDF file enables a conforming reader to quickly find the cross-reference table and certain special objects. (Beginning with PDF 1.5, some or all of the cross-reference information may alternatively be contained in cross-reference streams. The table shall contain a one-line entry for each indirect object, specifying the byte offset of that object within the body of the file. The cross-reference table contains information that permits random access to indirect objects within the file so that the entire file need not be read to locate any particular object. Beginning with PDF 1.5, the body can also contain object streams, each of which contains a sequence of indirect objects. The objects, as described above, represent components of the document such as fonts, pages and sampled images. The body of a PDF file consists of a sequence of indirect objects representing the contents of a document. Irrespective of the PDF version, a PDF file starts with a header containing unique identifier for PDF and the version of the format such as %PDF-1.x where x ranges from 1-7. PDF file contents are arranged in the following sequence inside the file. Once or more tokens are combined to form higher-level syntactic entities, principally objects, which are the basic data values from which a PDF document is constructed. PDF File Format SpecificationsĪ PDF file is a set of bytes that can be grouped in to tokens according to syntax rules defined by PDF specifications. It was on Jwhen PDF 2.0, known as ISO 32000-2:2017 was published which doesn’t include any non-standardized technologies. PDF 1.7, which became the ISO 32000-1, include some non-standardized proprietary technologies as well like Adobe XML Forms Architecture (XFA) and JavaScript extension for Acrobat.

The first version of PDF designated as PDF 1.0 which later went through revisions up to PDF 1.7.

But that doesn’t mean there are no software for creation or manipulation of PDF files. In most of the cases, existing documents are converted to PDF rather than creating a new PDF from scratch.

The PDF file format has full capability to contain information like text, images, hyperlinks, form-fields, rich media, digital signatures, attachments, metadata, Geospatial features and 3D objects in it that can become as part of source document. The purpose of this file format was to introduce a standard for representation of documents and other reference material in a format that is independent of application software, hardware as well as Operating System.
