The trailer section starts at byte offset 50291, includes 223 objects where the root element points to object 221 and the info element points to object 222. MACROSTRUCTURE The cross section of a tree can be divided into three basic parts: bark, cambium, and wood (Figure 3-3). Figure 2e,f indicated that the two cross-sections dilated with the decrease of scanning height. Figure 5.8 (right). PDF data types You don’t have to cut the tree down to see growth rings, because there is cambium in the branches as well that also allows them to grow in diameter. The cross-reference section contains one subsection that itself contains 223 objects. In the next section, we’ll take a look at the PDF structure’s basic data types.
