In 1993 the Jaws raster image processor from Global Graphics became the first shipping prepress RIP that interpreted PDF natively without conversion to another
format. The company released an upgrade to their Harlequin RIP with the same capability in 1997.
[109]
Agfa-Gevaert introduced and shipped Apogee, the first prepress workflow system based on PDF, in 1997.
Many commercial offset printers have accepted the submission of press-ready PDF files as a print source, specifically the PDF/X-1a subset and variations of the
same.
[110]
The submission of press-ready PDF files are a replacement for the problematic need for receiving collected native working files.
PDF was selected as the "native" metafile format for Mac OS X, replacing the PICT format of the earlier Mac OS. The imaging model of the Quartz graphics layer is
based on the model common to Display PostScript and PDF, leading to the nickname Display PDF. The Preview application can display PDF files, as can version 2.0 and
later of the Safari web browser. System-level support for PDF allows Mac OS X applications to create PDF documents automatically, provided they support the OS-
standard printing architecture. The files are then exported in PDF 1.3 format according to the file header. When taking a screenshot under Mac OS X versions 10.0
through 10.3, the image was also captured as a PDF; later versions save screen captures as a PNG file, though this behaviour can be set back to PDF if desired.
Some desktop printers also support direct PDF printing, which can interpret PDF data without external help. Currently, all PDF capable printers also support PostScript,
but most PostScript printers do not support direct PDF printing.
The Free Software Foundation once considered one of their high priority projects to be "developing a free, high-quality and fully functional set of libraries and programs
that implement the PDF file format and associated technologies to the ISO 32000 standard."
[111][112]
In 2011, however, the GNU PDF project was removed from the list of
"high priority projects" due to the maturation of the Poppler library,
[113]
which has enjoyed wider use in applications such as Evince with the GNOME desktop
environment. Poppler is based on Xpdf
[114][115]
code base. There are also commercial development libraries available as listed in List of PDF software.
The Apache PDFBox project of the Apache Software Foundation is an open source Java library for working with PDF documents. PDFBox is licensed under the Apache
License.
