The update usually appends additional elements to the end of the file. An example of real numbers can be seen below: The names in PDF documents are represented by a sequence of ASCII characters in the range 0x21 0x7E. The objects in object streams are consecutive and dont need to be stored in increasing order relative to object number. You can prefix or suffix a filename with the Bates number. The examples of names can be seen in the table below: Strings in a PDF document are represented as a series of bytes surrounded by parenthesis or angle brackets, but can be a maximum of 65535 bytes long. First we need to create the PDF document so that well then try to analyze it. Choose Add To Original File Names, and enter %BATES_NUMBER_KEY% in the Insert Before or Insert After fields as desired.

The key must be the name object, whereas the value can be any object, including another dictionary. command and specifying the name of the .tex file as an argument. The simplest page tree structure can consist of a single page tree node that references all of the page objects directly (so all of the page objects are leafs). We also need to remember that all the encoded data streams were removed and replaced with three dots for clarity and brevity. Lets open that PDF in a text editor like gvim and check out the trailer section. This further implies that all of the presented objects are in fact the actual pages of the PDF document and dont contain any further children nodes. Since every indirect object has its own entry in the cross-reference table, the indirect objects may be accessed very quickly. However, when I export/save to a PDF file, the header image moves down by about 3/16 .
