// 3.2.9 Indirect Objects
|
|
|

// Any object in a PDF file may be labeled as an indirect object. This gives the object
|
|
|
1128 |
// a unique object identifier by which other objects can refer to it (for example, as an
|
|
|
1129 |
// element of an array or as the value of a dictionary entry). The object identifier
|
|
|
1130 |
// consists of two parts:
|
|
|
1131 |
// * A positive integer object number. Indirect objects are often numbered sequentially
|
|
|
1132 |
// within a PDF file, but this is not required; object numbers may be
|
|
|
1133 |
// assigned in any arbitrary order.
|
|
|
1134 |
// * A non-negative integer generation number. In a newly created file, all indirect
|
|
|
1135 |
// objects have generation numbers of 0. Nonzero generation numbers may be introduced
|
|
|
1136 |
// when the file is later updated; see Sections 3.4.3, “Cross-Reference
|
|
|
1137 |
// Table,” and 3.4.5, “Incremental Updates.”
|
|
|
1138 |
// Together, the combination of an object number and a generation number uniquely
|
|
|
1139 |
// identifies an indirect object. The object retains the same object number and
|
|
|
1140 |
// generation number throughout its existence, even if its value is modified.
