Version 3.1
===============================================================================
Patchlevel 2 (Aug 16, 1995)
Changes from patchlevel 1:

New Features:

o JPEG (JFIF) pictures objects supported for PostScript output
o %Magnification: comment added to PostScript output showing magnification
o the points of arrow heads don't protrude past the endpoints of the object

Bugs Fixed:

o the radius of arc-box corners is limited to the half of the smaller of the
    two sides of the box to avoid PostScript errors
o pstex driver incorrectly omitted postscript text in pstex output
o set_linewidth was passed double instead of int from fdraw_arrow_head
    in genepic.c
o length of dotted line dots too small for high resolution printers
o recursion bug fixed where run-time would increase exponentially with nesting
    of compound objects
o %%BeginDocument:/EndDocument now surrounds imported EPS files
o open arrowheads on arcs were overwritten by arc lines
o bug in pattern fill code which made patterns appear solid black when
    using dvips
    Thanks to Tomas Rokicki ([e-mail]) for finding the fix
o line thickness wasn't adjusted for new resolution in epic, eepic, pic, tpic
    and pictex drivers
o dash length incorrect for Fig 3.x files in pic and pictex drivers
o -s option to fix text pointsize wasn't being honored
o documentation typo with regard to rigid text.  Rigid text means that the font
    size doesn't change when text is inside a compound object and that
    object is scaled in xfig.  Not used for fig2dev.
o certain machines don't handle atan2(y,0.0) so arcs with endpoints having the
    same x value were incorrectly calculated
o some machines don't calculate hypot(x,y) correctly so changed to sqrt(x*x+y*y)
    in arc_bound()
o bug in calculating BoundingBox for PostScript in compound objects
o cleared up confusion about -DNFSS and -DEPSF.  Here is the final word:

  Add -DNFSS to DEFINES list to use NFSS2 font selection for LaTeX texts
  Add -DEPSF to DEFINES list to use epsfig macros as distributed w/ LaTeX2e

     Hint: Users of LaTeX2e will probably want to include both of these
     options; users of LaTeX 2.09 will probably want to include neither.

o new tints added (fill values 21-40) for epic driver
     from Andre Eickler ([e-mail])
o pattern fill seg faulted for epic/eepic output (only PostScript has patterns)
o sanity check for font number
o font name "Modern" changed to more correct "Sans Serif" in documentation
o MetaFont driver only sent output to stdout
o version information (fig2dev -V) said "TransFig" instead of "fig2dev"
o getopt.c not needed for Solaris 2.x - #if (defined(...)) added in Imakefile
    for this
o removed duplicate #define of FALSE, TRUE and DEFAULT_FONT_SIZE in various
    drivers

---------------------------------------------------------------------------
Patchlevel 1 (Jan 24, 1995)
Changes from patchlevel 0:

Bugs Fixed:

o eps files with binary data (!) now handled correctly
o -f option to PostScript driver with unknown PostScript font name caused
    seg fault
o increased resolution of unitlength specifier in latex/epic drivers - was
    rounding 0.00083333 to 0.0008.
o dash length not set correctly for epic driver
o area fill values incorrectly interpreted for some drivers other than
    PostScript - this also made fig2dev outpus spurious %s%s(%d%d)}
    for epic/eepic
o linejoin set instead of linecap in postscript output
o sets linecap to ROUND for ellipses and closed splines with dotted lines
o defines showpage as null for included EPS files instead of removing the
    word "showpage" from them
o definition for XCOMM in Imakefiles for those running R4
o bug in freeing xpm image structure incompatible pointer type
o bug in fig2dev/Imakefile variable for including -ldbm explicitly
o removed -lnsl option from fig2dev/dev/Imakefile - imake files should
    automatically add this to the Makefile for Solaris (SVR4) systems
o note added to README that you must do "make" before "make install"
o bug in reading text for linux os - text size was set to 0
o bcopy changed to memcpy call in dev/readpics.c
o SVR4 condition added to transfig/transfig.h for including string.h
o variable in fig2dev/Imakefile and fig2dev/dev/Imakefile for include
    directory for xpm files if your xpm headers are not in the default X11
    include directory

---------------------------------------------------------------------------
Patchlevel 0 (Jan 9, 1995)

Changes from 3.0.0:

o NOTE:    An error in xfig version 3.0.0 incorrectly positioned objects on the
    canvas when reading older fig files.  New objects entered with 3.0 are
    correctly positioned.
    I apologize for the inconvenience.
*****    This is the only reason why the file protocol number has changed.

Bugs Fixed:

o error when figure was larger or partially off the page and user did not
    select multipage option (-M)
o newline() declared twice (inconsistently) in dev/gentpic.c
o errors in read.c for linux machines - caused font size 0
o Linux machines need LOCAL_LDFLAGS = -ldbm in fig2dev/Imakefile
o sys/types.h needed in dev/readpics.c for BSD machines

Version 3.0
===============================================================================
Transfig version 3.0.0 (Dec 22, 1994)

Changes from 2.1.8:

New Features:

o MetaFont driver added (from fig2mf)
    from Anthony Starks ([e-mail])
o "-n name" option to specify filename for PostScript Title (e.g. when using
    stdin)
o -x <offset> and -y <offset> options for PostScript output to shift figure on
    page.
o fig2dev/dev/Imakefile settings to:
     1. Use LaTeX2e commands for setting fonts. As LaTeX2e will become the
    official release by spring this year (we redefined the start of
    spring to be the date the LaTeX is released). This is a subtle
    problem in the outcome of transfig, but some old font changing
    commands behave differnet now.
     2. To use the \epsfig-package distributed with LaTeX2e instead
    of \special{psfile... for included PS-figures.
   They use two new defines in the dev/Imakefile: -DNFSS for 1., -DEPSF for 2.
   From Hendrik G. Seliger ([e-mail])
o arrow heads are pointed now for PostScript (they were blunt before)
o EPS Objects have been generalized to Picture Objects. Currently EPS, XBM
    XPM (X11 color pixmap) and GIF formats are recognized.
    Compressed (.Z) and gzipped (.z or .gz) files are also handled.
o new command-line option '-z' for PostScript output used to select a paper
    size from the list of A4, B5, Letter, Legal.
    from Jon Roma ([e-mail])
o change to the pstex driver so that when it sees text with a LaTeX font it
    handles it using the LaTeX text object routine, but not treating it
    as "special" text. This allows the pstex driver to take the "hint"
    the since the user is using LaTeX font specifiers, those should be
    used. The only people who could be adversely affected by the change
    would be those using LaTeX font names as convenient synonyms for
    PS font names who would now get LaTeX fonts instead. Probably not
    a problem.
    from Micah Beck ([e-mail])
o fig2ps2tex.sh for systems which don't have csh or dc.  Uses bc and awk.
    from Dave Raymond ([e-mail])


o changes to the file format (protocol).  See *xfig* Doc/FORMAT3.0 for details.
    Transfig will still read older Fig file formats.
Here are the features involving change to the protocol:
   o portrait/landscape, justification (center or flush left) and metric/inches
    indicators saved with figure file so is not necessary to supply the
    command-line args to specify them.  However they will override the file
    specification if given.
   o separate border and fill colors.
   o resolution is increased from 80 ppi to 1200 ppi.  This decreases jaggies.
    A side effect is that fig2dev can now read Fig files of any resolution.
   o there are now 32 colors - new ones are: gold, three shades each of blue,
    green, cyan, red, magenta, brown and pink.
   o in addition, there are now user-definable colors which are stored in the
    figure file as pseudo-objects of type 0 which define the rgb values
    in hexadecimal.  The color numbers range from 32 to 543 for a maximum
    of 512 user-defined colors.
   o more fill options - colors transition from black to full saturation
    (shades) and on to full white (tints, i.e. pastels).
    Or you can use one of 16 fill patterns - diagonal lines, bricks,
    shingles, crosshatch etc.
   o three line-join styles: miter (current style), round and bevel (see
    PostScript or Xlib reference for description)
   o three line-cap styles: butt (current style), round and projecting (see
    PostScript or Xlib reference for description)

Bugs fixed:

o circles/ellipses paths weren't being closed in postscript output - gap closed
o "%%Page: 1 1" added for single-page output for Document Structuring Compliancy
    (previously, Page: comment only appeared in multi-page figures)
o coord_system was declared extern in fig2dev/fig2dev.h.  This was incorrect.
o even/odd rule fill now used for filled objects as per xfig (PostScript)
o typo in fig2dev/dev/Imakefile said include -DA4d instead of -DA4 for A4 paper
o all orientations of rotated/flipped EPS objects correctly done now
o man pages for transfig claims to be able to read postscript files - this was
    never finished so it has been removed from the man pages.
o dotted lines with very small length caused SIGFPE
o typo in error message about unknown option
o added check for #if defined(SVR4) in addition to defined(SYSV)
o misplaced ';' in fig2dev.c gendev_null() proc
o added static declarations in genlatex.c genpictex.c and gentextyl.c
o better bounding box calculation
    from Uwe Bonnes ([e-mail])
o Tpic TeX font position 5 was "sl" (slanted) which doesn't exist
    from Edward Wang ([e-mail])

Version 2.1
===============================================================================

Transfig version 2.1.8 (Oct 1, 1993)
Changes from 2.1.7:

New Features:

Bugs fixed:

o thick line threshold increased from 1 to 2 for latex lines
o save/restore wraps EPS objects now
o specifing nonexistant font with -f caused coredump
    from Gordon W. Ross ([e-mail])
o newpath command given before EPS object for PostScript output
o moved definition of SetFigFont to better place
    from Bernd Raichle ([e-mail])
o #included sys/types for BSD4_3 systems in genps.c
o bug in eepic output - SetFigFont was being defined inside a \put
    from Vivek Khera ([e-mail])
o BoundingBox for EPS objects can be floating values
o shortened file name (fig2dev/dev/)def_setfigfont.c to setfigfont.c
o distribution version of fig2dev/dev/Makefile had (def_)setfigfont.c
    instead of (def_)setfigfont.o in LIBOBJS definition
o SUBDIR fig2dev/dev was missing from top-level Imakefile caused problems
    where make would say something like "No rule to make target
    dev/libtransfig.a"

---------------------------------------------------------------------------
Transfig version 2.1.7
Changes from 2.1.6:

o no longer writes over input file if there is an error in the command line
o added "%%Orientation: Landscape" comment for PostScript output in landscape
    orientation
o moved definition of SetFigFont from transfig into genpstex.c so that there
    is no need to run transfig for pstex output
o script pic2tpic was generating \ss instead of \sf for \fH
    from Mark Roth ([e-mail])
o changed header for Encapsulated postscript files from "%!PS-Adobe-2.0 EPSF"
    to "%!PS-Adobe-2.0 EPSF-2.0" which allows FrameMaker and ghostview to
    read them properly.
    from Vivek Khera ([e-mail])
o check for #ifdef SYSV to include string.h instead of strings.h in
    fig2dev/dev/genibmgl.c
o changed EXTRA_LIBRARIES to SYS_LIBRARIES in fig2dev/Imakefile so wouldn't
    clobber system-dependent flags in EXTRA_LIBRARIES
o fprintf and 'else' missing from genepic which caused incorrect information
    to be generated when drawing arcs using epic output
o removed dependencies on the X libraries (Imakefiles and Makefiles)
o SGI machines had trouble with hypot() which caused arrow heads to mess up
    from Malcolm Davis ([e-mail])
o Flipped EPS objects were incorrectly flipped on output
    from Brian Boyter ([e-mail])
o POLYLINES were being drawn in sections (10 points per section) which
    resulted in incorrect dashed line lengths and only one section
    filled if area fill was on
    from Peter Egelberg ([e-mail])
o added Sequent machines and Suns with SunOs < 4.1 to list of machines that
    don't have strstr()
    from Scott Erikson ([e-mail])
o removed PATCHLEVEL from patchlevel.h file - version number is complete with
    three parts (e.g. 2.1.6)
o removed "extern coord_system" from fig2dev.h (wasn't used by fig2dev)
o SPECIAL_CHAR split into three strings for systems which can't handle one
o -P flag dissappeared from eepic output language - reinstated

---------------------------------------------------------------------------
Version 2.1.6
Changes from 2.1.5:

o Courier-BoldItalic changed to Courier-BoldOblique for PostScript fonts
o "if" statement replaces copysign() call since some machines don't have it
o some backslashes ('\') corrected in printf statements in transfig/mkfile.c and
    fig2dev/iso2tex.c
o changed header for postscript files from "%!" to "%!PS-Adobe-2.0" when using
    -P (showpage) option and "%!PS-Adobe-2.0 EPSF" otherwise (Encapsulated)
o corrupt transfig/Imakefile and typo (SCRS instead of SRCS)
o some variables (cur_thickness and coord_system) were multiply defined in
    various drivers in fig2dev/dev - made those static
