Creating and Modifying PDF Documents
Converting PDF Documents to XML Format

It is also possible to use the
addWatermarkFromText
method to create watermarks. In
this next example, the word
Confidential
is placed in the center of all the pages of the
document, and its font helps it stand out:
this.addWatermarkFromText(
"Confidential",
0,
font.Helv,
24,
color.red
);
Adding Headers and Footers
As you learned in
Adding Watermarks and Backgrounds,
you may use Acrobat JavaScript’s
watermarking functionality to add headers and footers to your documents by invoking the
doc
object’s
addWatermarkFromText
method, which can be applied as a header or
footer by specifying the placement of the text at the top or bottom of the page. The
following example places a multiline header, one inch down and one inch over from the
top right corner of all the pages within the current document:
this.addWatermarkFromText({
cText: "Confidential Document",
nTextAlign: 2,
nHorizAlign: 2,
nVertAlign: 0,
nHorizValue: -72,
nVertValue: -72
});
Converting PDF Documents to XML Format
Since XML is often the basis for information exchange within Web Services and enterprise
infrastructures, it may often be useful to convert your PDF documents into XML format.
It is a straightforward process to do this using the
doc
object’s
saveAs
method, which not
only performs the conversion to XML, but also to a number of other formats.
In order to convert your PDF document to a given format, you will need to determine the
device-independent path to which you will save your file, and the conversion ID used to
save in the desired format. A list of conversion IDs for all formats is provided in the ASN
documentation. For XML, the conversion ID is
"com.adobe.acrobat.xml-1-00".
The following code converts the current PDF file to
C:\test.xml:
this.saveAs("/c/test.xml", "com.adobe.acrobat.xml-1-00");
