Updated: xpdf-3.02-1: An open source viewer for Portable Document Format (PDF) files

Tue Apr 8 07:51:00 GMT 2008

Hi

A new version of 'xpdf' has been uploaded to a server near you.

DESCRIPTION:
============
Xpdf is an open source viewer for Portable Document Format (PDF)
files. (These are also sometimes also called 'Acrobat' files, from the 
name of Adobe's PDF software.) The Xpdf project also includes a PDF text 
extractor, PDF-to-PostScript converter, and various other utilities. Xpdf 
runs under the X Window System on UNIX, VMS, and OS/2. The non-X components 
(pdftops, pdftotext, etc.) also run on Win32 systems and should run on pretty 
much any system with a decent C++ compiler. Xpdf is designed to be small and 
efficient. It can use Type 1 or TrueType fonts.

Cygwin NEWS:
============

 o Update to latest upstream release
 o Incorporated latest security patches from the xpdf homepage
 o Changed to cygport build framework
 o Language support packages included

xpdf NEWS:
===============

Added anti-aliasing for vector graphics; added the vectorAntialias
  xpdfrc option; added the "-aaVector" switch to xpdf and pdftoppm.
Implemented stroke adjustment (always enabled by default, ignoring the
  SA parameter, to match Adobe's behavior), and added the strokeAdjust
  xpdfrc command.
Support PDF 1.6 and PDF 1.7.
Added support for AES decryption.
Added support for OpenType fonts (only tested with 8-bit CFF data so
  far).
Added user-configurable key/mouse bindings - the bind/unbind xpdfrc
  commands.
Cleaned up the full-screen mode code and added the ability to toggle
  it on the fly (the default key binding is alt-f).
Pdfimages with the -j option now writes JPEG files for 1-component
  (grayscale) DCT images, in addition to 3-component (RGB) images.
Fixed bugs in handling sampled (type 0) functions with 32-bit
  samples.
Fixed some things to support DeviceN color spaces with up to 32
  colorants.
Pdftops now constructs the %%Creator and %%Title DSC comments from the
  relevant information in the PDF Info dictionary.
Tweak the TrueType font encoding deciphering algorithm.
Added the "mapUnkownCharNames" xpdfrc option.
Fix a bug (that only showed up with certain window managers) in the
  intermediate resize event optimization.  [Thanks to Michael Rogers.]
Check for a broken/missing embedded font (this was causing xpdf to
  crash).
Added support for transfer functions in PostScript output.
Be a bit more tolerant of Link destinations that contain null values
  for positioning parameters.
Use ordered dot dithering instead of clustered dot dithering at 
  resolutions below 300 dpi (for monochrome output).
Fixed security holes (bounds checking issues) in several places.
Don't bother creating a SplashFont (allocating memory) for fonts that
  are only used for hidden text - this avoids problems with fonts of
  unreasonably large sizes.
Clipping in TextOutputDev was off for characters on the left edge of
  the page.
The scn and SCN operators weren't correctly handling colors with more
  than four components.
FoFiType1::writeEncoded wasn't always correctly finding the end of the
  encoding.
Use the ColorTransform parameter in the DCTDecode stream dictionary.
Type 3 fonts are allowed to have a bbox of [0 0 0 0], which means
  "unspecified" -- don't issue error messages in that case.
Perform the transform (to device space) in Splash instead of in
  SplashOutputDev -- this is needed to correctly handle round joins
  and caps on stroked paths.
PSOutputDev now rasterizes any pages that use transparency.
Limit the crop, bleed, trim, and art boxes to the edges of the media
  box (per the PDF spec).
Change GString to increase the allocation increment by powers of two.
Handle whitespace in hex strings in CMap files/streams.
Use strings instead of names for separation colorant names in
  PSOutputDev.
For explicitly masked images where the mask is higher resolution than
  the image, use the soft mask code.
Avoid problems with very large x-steps in the PostScript output for
  tiling pattern fills.
Avoid a divide-by-zero in stitching functions which have a subfunction
  with empty bounds.
Honor the "Hidden", "NoView", and "Print" flags on annotations.
Rewrote the pixel rendering code in Splash to use a single set of
  pixel pipeline functions.
Added support for transparency groups and soft masks.
Fixed the transparency blend functions to match the addendum published
  by Adobe.
Changed Splash/SplashBitmap to store alpha in a separate plane.
Setting the color space now selects the correct default color for that
  color space.
Remove the mutex lock from GlobalParams::getErrQuiet() to avoid a
  deadlock when parseCIDToUnicode() or parseUnicodeToUnicode() calls
  it from inside a locked section.
Added error checking (on the argument count) in the sc/SC/scn/SCN
  operators.
Skip over notdef glyphs in TrueType fonts (which sometimes get drawn
  as little boxes), to match Adobe's behavior.
Painting operations in a Separation color space with the "None"
  colorant or a DeviceN color space with all colorants set to "None"
  never mark the page.
Fixed an obscure bug in the JPX decoder - it wasn't reading the extra
  stuffing byte in the case where the last byte of a packet header was
  0xff.
Change the TrueType font parser (FoFiTrueType) to change the glyph
  count rather than report an error if the 'loca' table is too small.
Fixed a couple of bugs in the JBIG2 decoder.
Added stochastic clustered dot dithering.
Added the screenType, screenSize, screenDotRadius, screenGamma,
  screenBlackThreshold, and screenWhiteThreshold xpdfrc settings.
PSOutputDev now correctly handles invalid Type 3 charprocs which don't
  start with a d0 or d1 operator
FreeType 2.2.x support - get rid of the FT_INTERNAL_OBJECTS_H include,
  and add some 'const' declarations.
Handle PDFDocEncoding in Info dictionary strings.
Tweak the xref repair code - ignore whitespace at the start of lines
  when looking for objects.
Added the "-exec" switch to xpdf.
Removed the xpdf.viKeys X resource.
Changed the color key / explicit masked image code in PSOutputDev to
  generate better PS code, including a Level 3 option.
Tweaked the DEBUG_MEM code for performance.
Move the JBIG2 global stream reading code into reset() instead of the
  constructor - this way, pdftotext doesn't end up reading the global
  stream.
Added the "-preload" option to pdftops and the psPreload xpdfrc
  command.
Added the "zoom to selection" command (on the popup menu).
Fix a bug (in xpdf/pdftoppm/pdftops) with tiling patterns whose bbox
  size is different from their xStep/yStep.
Implemented stroke with pattern color spaces.
Following a link to a page whose CropBox was different from the
  MediaBox was resulting in an incorrect scroll position.
Parse truncated date strings from the Info dictionary correctly.
Change FoFiType1 to handle Type 1 fonts with two /Encoding keys.
Extend the PSOutputDev shaded fill code to handle DeviceCMYK shaded
  fills in level2sep and level3sep modes.
Detect infinite loops in the Page tree.
Optimized the ASCII85Encoder code.
Tweaked the text extractor to do a better job of lining up rows of
  text.
Leave images compressed (or re-compress them with RLE) in PostScript
  output when setting up images for forms and Type 3 fonts (or with
  -preload).
Extend FoFiType1 to handle Type 1 fonts with octal character codes in
  their encodings.
Use a custom string formatter to avoid problems with locale-based decimal
  formatting (commas instead of periods) in PS output.
Allow comments in PostScript-type functions.
Change the TrueType font parser (FoFiTrueType) to delete glyf table
  entries that are too short.
