CHANGES IN V1.28.15
- pdftops: In pdftops identify old LaserJets more precisely
for working around PostScript interpreter bugs, older
printers need Poppler, newer models need Ghostscript
CHANGES IN V1.28.14
- pdftopdf: Correct the output when suppressing auto-rotation
(option "nopdfAutoRotate"). Depending on the situation pages
got cropped in the wrong orientation or de-centered.
- pdftopdf: Correct the output when the
"orientation-requested" or the "landscape" option is
supplied. Output could be de-centered,
portrait-oriented pages be wrongly cropped and division of
the output page into cells for N-up done in the wrong
orientation.
- rastertopdf: In PCLm output mode the filter failed to
generate PCLm if the printer has no
"pclm-source-resolution-default" IPP attribute.
CHANGES IN V1.28.13
- pdftopdf: Fix N-up printing when paper is taken
long-edge-first by the printer.
- pdftopdf: Fix cropping ("print-scaling=none" and
"print-scaling=fill") when paper is taken long-edge-first by
the printer.
- pdftops: Use Poppler for all Apple LaserWriter models.
CHANGES IN V1.28.12
- imagetoraster, imagetopdf: Fixed comparison of the image
size with the page size for print-scaling=auto. The image
size in pixels was compared with the page size in PostScript
points (1/72 inch).
- imagetoraster, imagetopdf: Fixed the "print-scaling=none"
(crop-to-fit) mode, also use crop-to-fit always when
requested, do not fall back to fit-to-page when the image
size differs significantly from the page size.
- libcupsfilters: Changed the default PPI resolution for
images as input files from 128 to 200.
- implicitclass: Do not check availability of "gs" and
"pdftops" executables, instead, check by the presence of
"gstoraster" and "pdftoraster" filters whether we have
configured cups-filters for Ghostscript and/or Poppler use.
- libcupsfilters: In the PPD generator for the driverless
utility and cups-browsed add "*cupsFilter2: ..." lines for
all supported driverless data formats (PDF, Apple/PWG
Raster, PCLm), and add lines for legacy data formats (PCL,
PostScript) only if no driverless formats available.
- libcupsfilters: Always use encryption for ipps. RFC7472
requires that 'ipps' must be used over HTTPS, but the
driverless utility does not enforce encryption.
- serial: Add a 10-msec sleep and at the end add a tcdrain().
For some unknown reason, every printing file need sleep a
little time to make sure the serial printer receive data is
right.
- libcupsfilters: Fix resolver functions for DNS-SD-based
URIs, to make resolve_uri() also work when DEVICE_URI env
variable is set and to make ippfind_based_uri_converter()
not re-direct stdin.
- pdftopdf: Set default for print-scaling to avoid "should
never happem" log messages and undefined behavior.
- pdftopdf: Fix orientation-requested = 0. Consider
this as "automatic selection and not as error.
- pdftopdf: Fixed all combinations of print-scaling and
number-up for printers with asymmetric margins (top !=
bottom or left != right) and for input files containing
pages with different sizes and/or orientations. Fixes
backported from 2.x branch.
- pdftopdf: Add 2% tolerance for input size larger than output
page when "print-scaling=auto" or "print-scaling=auto-fit"
is used and too large input pages should be scaled, fitting
documents not. This prevents a random-looking behavior if
input and output page size seem to be equal, but in reality
there are slight differences between size dimensions.
CHANGES IN V1.28.11
- libcupsfilters: Let PPD generator take default ColorModel
from printer.
- Braille: In vectortopdf check inkscape version to call
inkscape with the correct command line.
- Build system: Make missing DejaVuSans.ttf non-fatal in
./configure as the font is only needed for test programs,
not for actual use of cups-filters.
- libcupsfilters: In imagetoraster() fixed crash with SGray.
- cups-browsed: Naming of local queues is matched to CUPS'
current naming of temporary queues (no leading or trailing
underscores), to avoid duplicates in print dialogs which
support CUPS' temporary queues.
- libcupsfilters: Make cupsRasterParseIPPOptions() work correctly
with PPDs (Issue #436).
- libcupsfilters: Let colord_get_profile_for_device_id() not
return empty file name, to avoid error messages in CUPS
error_log.
- foomatic-rip: Debug message was wrongly sent to stdout and
not to log
