To be 1.2 or 1.3

[PN...@directsourcing.com]

Here are the features that were new in PDF 1.3. So if we stick to pdf1.2 we
will not be able to have these features in fop. Now let's vote on the
features given below that are must in fop. Another thing to keep in mind is
that even if these features are present in the pdf file, it will work on
viewers supporting upto pdf 1.2 spec.


--------------------------------------------------------------
<pdfspec>
PDF 1.3 adds support for the new features of the Adobe imaging model, as
defined in PostScript 3, as well as other features. These include the
following:
* A facility for storing files converted from the World Wide Web in PDF
files. (Section 6.16, "Web Capture")

* Digital signatures. (Section 6.14.12, "Signature field")

* A facility for representing the logical structure of a document
independent of its graphic structure. (Section 6.17, "Logical Structure in
PDF")

* Alternate representations for a single image. (Section 7.13.3, "Alternate
images")

* Embedding files of any type within a PDF document. (Section 7.4.3,
"Embedded File streams")

* Support for JavaScript. (Section 6.14.13.4, "JavaScript Action")

* Enhanced page numbering. (Section 6.2.2, "PageLabel dictionaries")

* Information relating to trapping. (Section 6.6.16, "PDF Trapping")

* Support for left-to-right and right-to-left reading direction. (Section
6.2.1, "Viewer preferences")

* A facility for representing color separations. (Section 6.4.2, "Separated
PDF")

* New types of functions. (Section 7.14, "Functions")

* New colorspaces: DeviceN and ICCBased.(Section 7.12, "Color spaces")

* Smooth shading. (Section 7.18, "Smooth Shading") A section of Chapter 14
in previous editions, showing how to emulate blends with images, has been
removed from the new edition, since blends are now built in to PDF.

* Masked images. (Section 7.13.5, "Masking images by position")
