ghostscript (9.14~dfsg-0ubuntu1) utopic; urgency=medium
* New upstream release
- Ghostscript 9.14
- pdfwrite now uses the same color management engine as Ghostscript
rendering devices (by default LCMS2). This provides much better
control over color conversion and color management generally, but
will result in some small color differences when compared to the
old system.
It is no longer necessary to specify UseCIEColor (and we very much
encourage you not to do this) or the ProcessColorModel if you want
to convert a PDF file to a specific color space, simply set the
ColorConversionStrategy appropriately.
We do not expect any major problems to arise with this new code,
but for the duration of this release a new switch -dPDFUseOldCMS
is available which will restore the old color management. See:
Color Conversion and Management
Please note that due to constraints of the PDF/A-1 specification,
the new color management does not yet apply when producing PDF/A
files.
- A new device 'eps2write' has been added which allows for the
creation of EPS files using the ps2write device instead of the old
(deprecated and removed) pswrite device. This produces
considerably better quality EPS files than the old epswrite device
which is now also deprecated and will be removed in a future
release.
- ps2write now has a feature to allow customisation of the output
for specific devices. Please see PSDocOptions and PSPageOptions
described in ps2ps2.htm Additional Distiller Params
- Ghostscript now reduces memory usage when processing PDF files
that use transparency and output is to display devices such as
Windows display or x11 (i.e. devices that are strictly full
framebuffer devices), and to high level vector devices that cannot
reproduce the PDF transparency model, such as the ps2write device
or pdfwrite when 'flattening' to PDF 1.3 or earlier
(-dCompatibilityLevel=1.3). This uses banding (clist) files to
render the transparent areas in bands to reduce memory use, and
unlike the existing page level banding, this is hidden from the
target device.
- Ghostscript can now collect information for pages in temp files
(in Ghostscript's clist format), then render and output pages for
the job in arbitrary order, including normal, reverse, odd, even,
or any order or subset of the pages. This is controlled with the
--saved-page=___ option. (Note that this only applies to rendering
devices, and not high level devices such as pdfwrite and
ps2write.) See: Deferred Page Rendering
- The Ghostscript device architecture has been extended so that,
when rendering bands into multiple threads, it is now possible to
perform post-processing in multiple threads, such as downscale,
post-render halftoning, or compression. Previously, post
processing was only possible in the single main thread. This can
improve performance significantly.
- Ghostscript has a new "pwgraster" output device for PWG Raster
output
- The CUPS device now has improved support for PPD-less printing
- Plus the usual round of bug fixes, compatibility changes, and
incremental improvements.
