       SECTION 10.9                                                               Web Capture



       For example:
          / ADBE : H2PDF : 1 . 0 : HTML

       Note that all fields in the internal name are case-sensitive. The company field
       must conform to the naming guidelines described in Appendix E. The values of
       the other fields are unrestricted, except that they must not contain a colon.

       Note: It must be possible to make a deep copy of a command settings dictionary
       without explicit knowledge of the settings it may contain. To facilitate this operation,
       the directed graph of PDF objects rooted by the command settings dictionary must
       be entirely self-contained; that is, it must not contain any object referred to from
       elsewhere in the PDF file.


10.9.5 Object Attributes Related to Web Capture

       A given page object or image XObject can belong to at most one Web Capture
       content set, called its parent content set. However, the object has no direct pointer
       to its parent content set. Such a pointer might present problems for an application
       that traces all pointers from an object to determine, for example, what resources
       the object depends on. Instead, the object’s ID entry (see Table 3.27 on page 145
       and Table 4.39 on page 340) contains the digital identifier of the parent content
       set, which can be used to locate the parent content set via the IDS name tree in the
       document’s name dictionary. (If the IDS entry for the identifier contains an array
       of content sets, the parent can be found by searching the array for the content set
       whose O entry includes the child object.)

       In the course of creating PDF pages from HTML files, Web Capture frequently
       scales the contents down to fit on fixed-sized pages. The PZ (preferred zoom)
       entry in a page object (see “Page Objects” on page 144) specifies a magnification
       factor by which the page can be scaled to undo the downscaling and view the
       page at its original size. That is, when the page is viewed at the preferred magnifi-
       cation factor, one unit in default user space corresponds to one original source
       pixel.
