ShowPDF (procedure)

Displays a page of a PDF image resource.

Syntax

showpdf( resname, pagenum, width, height )

Argument

resname

String value containing either the name of the PDF resource within the document, or the path to a PDF file .

pagenum

Integer value specifying the page number within the PDF image resource.

width, height

Measure values specifying the width/height, in inches, the PDF page occupies when it displays. Specifying a value of zero for

one but not both of the two dimensions scales the PDF page to fit the non-zero dimension. Specifying both a width and a height

scales the PDF page to the best fit possible with that width and height, while maintaining its aspect ratio. Specifying both a

width and a height of zero displays the PDF page at its default resolution.

Code Sample Example

This example displays page 5 of the PDF image resource ’new_models’, at its default resolution.

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.
