Code Sample Example

Example

showpdf('new_models', 5, 0, 0)

Elements

$element (procedure)

Executes the specified document element (object, page, resource, etc.). Note that in the case of a page, this procedure

executes both the content of the page and the paper handling properties of the page. The height and width of thecalling page

aretherefore set to the same values as those set by the called page.

Recall that every element in a document has a unique name. You cantherefore call any element in the document at any time.

For example, the first page of a medical record document may contain a headerlisting all of the patient information, while

other pagesin the document scale that same header to fit in the lower left corner ofeach page. Any modification you sub-

sequently make to the headeris automatically reflected throughout the document.
