              with the  unicodeMap  command  (see  above).   This
              defaults to "Latin1".

       textEOL unix | dos | mac
              Sets  the  end-of-line  convention  to use for text
              output.  The options are:

                  unix = LF
                  dos  = CR+LF
                  mac  = CR

              (This can be overridden with the "-eol"  switch  on
              the  command  line.)  The default value is based on
              the OS where xpdf and pdftotext were built.

       textPageBreaks yes | no
              If set to "yes", text extraction will  insert  page
              breaks  (form feed characters) between pages.  This
              defaults to "yes".

       textKeepTinyChars yes | no
              If set to "yes",  text  extraction  will  keep  all
              characters.   If  set to "no", text extraction will
              discard tiny  (smaller  than  3  point)  characters
              after  the first 50000 per page, avoiding extremely
              slow run times for PDF files that use special fonts
              to  do shading or cross-hatching.  This defaults to
              "no".

                                                               ()

2 ISCELLANEOUS_SETTING

       initialZoom percentage | page | width
              Sets the initial zoom factor.  A number specifies a
              zoom percentage, where 100 means 72 dpi.   You  may
              also  specify 'page', to fit the page to the window
              size, or 'width', to fit the page width to the win-
              dow width.

       continuousView yes | no
              If set to "yes", xpdf will start in continuous view
              mode, i.e., with one vertical screoll bar  for  the
              whole document.  This defaults to "no".

       enableT1lib yes | no
              Enables  or  disables  use  of t1lib (a Type 1 font
              rasterizer).  This is only  relevant  if  the  Xpdf
              tools    were    built    with    t1lib    support.
              ("enableT1lib"  replaces  the  old   "t1libControl"
              option.)  This option defaults to "yes".

       enableFreeType yes | no
              Enables  or  disables use of FreeType (a TrueType /
              Type 1 font rasterizer).  This is only relevant  if
              the  Xpdf  tools  were built with FreeType support.
              ("enableFreeType" replaces  the  old  "freetypeCon-
              trol" option.)  This option defaults to "yes".

       antialias yes | no
              Enables  or  disables font anti-aliasing in the PDF
              rasterizer.  This option affects all font rasteriz-
              ers.   ("antialias" replaces the anti-aliasing con-
              trol  provided  by  the  old   "t1libControl"   and
              "freetypeControl" options.)  This default to "yes".

       vectorAntialias yes | no
              Enables or disables anti-aliasing of vector  graph-
              ics in the PDF rasterizer.  This defaults to "yes".

       strokeAdjust yes | no
              Enables  or  disables  stroke   adjustment.    This
              defaults to "yes".

       screenType dispersed | clustered | stochasticClustered
              Sets  the  halftone screen type, which will be used
              when generating a monochrome (1-bit)  bitmap.   The
              three  options  are  dispersed-dot dithering, clus-
              tered-dot dithering (with a round dot and 45-degree
              screen angle), and stochastic clustered-dot dither-
              ing.  By default, "stochasticClustered" is used for
              resolutions  of 300 dpi and higher, and "dispersed"
              is used for resolutions lower then 300 dpi.

       screenSize integer
              Sets the  size  of  the  (square)  halftone  screen
              threshold  matrix.   By default, this is 4 for dis-
              persed-dot dithering, 10 for clustered-dot  dither-
              ing,  and  100 for stochastic clustered-dot dither-
              ing.

       screenDotRadius integer
              Sets the halftone screen dot radius.  This is  only
              used when screenType is set to stochasticClustered,
              and it defaults to 2.  In clustered-dot  mode,  the
              dot  radius is half of the screen size.  Dispersed-
              dot dithering doesn't have a dot radius.

       screenGamma float
              Sets the halftone screen gamma  correction  parame-
              ter.   Gamma  values greater than 1 make the output
              brighter; gamma values less than 1 make it  darker.
              The default value is 1.

       screenBlackThreshold float
              When  halftoning,  all  values below this threshold
              are forced to solid black.   This  parameter  is  a
              floating  point  value  between  0  (black)  and  1
              (white).  The default value is 0.

       screenWhiteThreshold float
              When halftoning, all values  above  this  threshold
              are  forced  to  solid  white.  This parameter is a
              floating  point  value  between  0  (black)  and  1
              (white).  The default value is 1.

       urlCommand command
              Sets  the  command executed when you click on a URL
              link.  The string "%s" will be  replaced  with  the
              URL.  (See the example below.)  This has no default
              value.

       movieCommand command
              Sets the command executed when you click on a movie
              annotation.   The string "%s" will be replaced with
              the movie file name.  This has no default value.

       mapNumericCharNames yes | no
              If set to "yes", the Xpdf tools will attempt to map
              various  numeric  character names sometimes used in
              font subsets.  In some cases this leads  to  usable
              text,  and  in other cases it leads to gibberish --
              there is no way for Xpdf to tell.  This defaults to
              "yes".

       mapUnknownCharNames yes | no
              If  set to "yes", and mapNumericCharNames is set to
              "no", the Xpdf tools  will  apply  a  simple  pass-
              through  mapping  (Unicode  index = character code)
              for all unrecognized glyph names.  In  some  cases,
              this  leads  to  usable text, and in other cases it
              leads to gibberish -- there is no way for  Xpdf  to
              tell.  This defaults to "no".

       bind modifiers-key context command ...
              Add  a  key or mouse button binding.  Modifiers can
              be zero or more of:

                  shift-
                  ctrl-
                  alt-

              Key can be a regular ASCII character,  or  any  one
              of:

                  space
                  tab
                  return
                  enter
                  backspace
                  insert
                  delete
                  home
                  end
                  pgup
                  pgdn
                  left / right / up / down        (arrow keys)
                  f1 .. f35                       (function keys)
                  mousePress1 .. mousePress7      (mouse buttons)
                  mouseRelease1 .. mouseRelease7  (mouse buttons)

              Context is either "any" or a comma-separated combi-
              nation of:

                  fullScreen / window       (full screen mode on/off)
                  continuous / singlePage   (continuous mode on/off)
                  overLink / offLink        (mouse over link or not)
                  scrLockOn / scrLockOff    (scroll lock on/off)

              The context string can include  only  one  of  each
              pair in the above list.

              Command  is  an Xpdf command (see the COMMANDS sec-
              tion of the xpdf(1) man page for details).   Multi-
              ple commands are separated by whitespace.

              The bind command replaces any existing binding, but
              only if it was defined for  the  exact  same  modi-
              fiers,  key,  and  context.  All tokens (modifiers,
              key, context, commands) are case-sensitive.

              Example key bindings:

                  # bind ctrl-a in any context to the nextPage
                  # command
                  bind ctrl-a any nextPage

                  # bind uppercase B, when in continuous mode
                  # with scroll lock on, to the reload command
                  # followed by the prevPage command
                  bind B continuous,scrLockOn reload prevPage

              See the xpdf(1) man page for more examples.

       unbind modifiers-key context
              Removes a key binding  established  with  the  bind
              command.  This is most useful to remove default key
              bindings before establishing new ones (e.g., if the
              default key binding is given for "any" context, and
              you want to create new key  bindings  for  multiple
              contexts).

       printCommands yes | no
              If  set  to  "yes", drawing commands are printed as
              they're  executed  (useful  for  debugging).   This
              defaults to "no".

       errQuiet yes | no
              If  set  to  "yes",  this  suppresses all error and
              warning messages from all of the Xpdf tools.   This
              defaults to "no".

                                                               ()
