| 7 | * This extension adds bookmark support. The method to add a bookmark is:
|
---|
| 8 | *
|
---|
| 9 | * function Bookmark(string txt [, int level [, float y]])
|
---|
| 10 | *
|
---|
| 11 | * txt: the bookmark title.
|
---|
| 12 | * level: the bookmark level (0 is top level, 1 is just below, and so on).
|
---|
| 13 | * y: the y position of the bookmark destination in the current page. -1 means the current position. Default value: 0.
|
---|
| 14 | *
|
---|
| 15 | * The title must be encoded in ISO Latin-1.
