(Upstream) Version 9.06 (2012-08-08)
This is the sixth full release in the stable 9.x series.
Highlights in this release include:
* PDF/A-2 - pdfwrite now supports the creation of PDF/A-2 files. The 'PDFA'
command line switch can now take a numeric parameter:
+ 0 = not PDF/A compliant
+ 1 = PDF/A-1b compliant
+ 2 = PDF/A-2b compliant
Simply specifying "-dPDFA" continues to have the old behaviour of creating
PDF/A-1b files. For PDF/A-2 the command line should include "-dPDFA=2".
* pdfwrite "Server mode" - pdfwrite can now be run in "server mode" which
allows the device to be closed without closing the interpreter. This means
it is no longer necessary to terminate GS before starting a new PDF
conversion. This leads on to:
* pdfwrite now supports the "%d" format in the OutputFile switch. If this is
set then pdfwrite will output each page of input to an individual file.
* ps2write - recent exposure to a range of PostScript devices has thrown up
some interesting deficiencies in those devices. ps2write now emits
PostScript in slightly different ways in order to produce output on a wider
variety of devices. In some cases this also results in improved print times
but it is still important to set the resolution appropriately for the
output device, especially if the input contains transparency.
* Ghostscript can now use output intents defined in PDFs by using the
"-dUsePDFX3Profile" command line option. See ICC Color Parameters for
details.
* tiffsep/tiffsep1: support for large numbers of separations improved. The
previous implementation of those devices utilised a "compressed color
encoding" to represent the tints for all the plates in one 64 bit value. As
the number of plates increased, fewer bits were available for the tint for
each plate, ultimately resulting in an "unencodable pixels" error. These
revisions remove the reliance on the compressed color encoding, thus
ensuring that we have a consistent color bit depth, regardless of the
number of plates, and ensuring the "unencodable pixels" error will never
occur.
Also as a result of these changes, there are substantial performance
improvements in jobs with separations and transparency.
* tiffsep, psdcmyk and psdrgb now support the "downscaler" functionality.
This brings the "tiffscaled" style functionality to the DeviceN output
devices, so jobs can be rendered internally in contone and at a high
resolution, and the output optionally downsampled by a level specified by
"-dDownScaleFactor=n", and also optionally error diffused to 1bpp output.
* Third party libraries: libtiff, libpng, libjpeg , Freetype and zlib have
all be updated.
* clist storage, for rendering pages in bands, is now a run-time option:
-sBandListStorage={file|memory}.
* Plus the usual round of bug fixes, compatibility changes, and incremental
improvements.
