TransFig is a set of tools for creating TeX documents with graphics
which are portable, in the sense that they can be printed in a wide
variety of environments.

TransFig 3.2.4 is available from ftp://epb.lbl.gov/xfig and www.xfig.org and usually
from any CTAN (Comprehensive TeX Archive Network) site such as 
ftp://ftp.cdrom.com/pub/tex/ctan/.
See http://math.nmu.edu/Web/TeXArchives/ctansite.html for a long list of CTAN sites.

Be sure to set binary mode when transferring.

The transfig directory contains the source for the transfig command
which generates a Makefile which translates Fig code to various graphics
description languages using the fig2dev program.  In previous releases,
this command was implemented as a shell script.

The fig2dev directory contains the fig2dev program for translating from Fig code
to other graphics desciption languages.  The dev subdirectory contains a
library of output drivers used by fig2dev.

Drivers currently exist for the following graphics langauges:
AutoCad slide, BOX, (E)EPIC macros, LaTeX picture environment, 
Encapsulated Postscript (with or without ASCII or TIFF (binary) previews), GIF,
IBM-GL (HPGL), EMF (Enhanced Metafile), JPEG, MF (METAFONT), MP & MMP (MetaPost
and Multi-MetaPost), PCX, PIC, PiCTeX, PNG, PostScript, SVG (scalable vector
graphics), TeXtyl, TIFF, TK (tcl/tk), TPIC, XBM (X11 Bitmap), and XPM (X11 Pixmap).

I have taken over the maintenance of TransFig from Micah Beck so please send any
bug notices, fixes, contributions etc to me at xfig-bugs@epb1.lbl.gov.

Changes to Transfig/fig2dev for version 3.2.4:

NEW FEATURES
	o SVG (Scalable Vector Graphics) driver from Anthony Starks, modified
	  by Brian Smith and greatly enhanced by Martin Kroeker
	o ASCII and Binary (TIFF) preview bitmap options for PostScript and EPS
	  export.  The latter is useful for Microsoft products which require a
	  TIFF preview to display EPS on the screen. Use -A for ASCII preview,
	  use -C for color TIFF or -T for monochrome TIFF preview.  These all
	  require ghostscript to work.  If you don't have ghostscript, the
	  export will continue without a preview.
	o JPEG encoding (DCT) now used for EPS/PostScript output. This greatly
	  reduces the size of the generated PostScript.  Gleaned with permission
	  from jpeg2ps program written by Thomas Merz.
	  As a result of this, the jpeg library is no longer needed, although xfig
	  still needs it for JPEG support.
	o Background (-g) option for tk export honored now
	o Additional JPEG file format (EXIF) added. These usually come from
	  digital cameras.
	o -N Option to convert colors to grayscale on export.
	o -b option for CGM export to produce binary CGM using ralcgm. You must,
	  of course have ralcgm installed on your system to use this.
	o Translations of LATEX.AND.XFIG document into two popular Chinese
	  encodings (GB2312 and Big5).  These are called LATEX.AND.XFIG.zh_CN
	  and LATEX.AND.XFIG.zh_TW respectively.
	  From Mendel Chan
	o The default for multi-page output (PostScript) is to NOT overlap pages
	  now.  This is to allow multiple, independent pages of figures.
	  The -O option has been added to force page overlap, e.g. to cut and
	  paste pages together to make posters (the original use for multipage).
	o Added EMF (Enhanced MetaFile) conversion genemf.c
	  from Mike Schrick (based on the CGM driver from Philippe Bekaert
	o New grid option (-G) to draw grid on page.  Specify minor and/or major
	  tick spacing in one of several units.  For example, "-G .25:1cm" draws
	  a thin, gray line every .25 cm and a thicker gray line every 1 cm.
	  Specifying "-G 1in" draws a thin line every 1 inch.  See man pages for
	  all units.  Fractions may be used, e.g. -G 1/16:1/2in will make a thin
	  line every 1/16 (0.0625) inch and a thick line every 1/2 (0.5) inch.
	  Only implemented in PostScript, EPS, PDF, and bitmap (GIF, JPEG, etc)
	  drivers for now.
	o Perk/Tk driver from Slaven Rezic (rezic@onlineoffice.de)
	o Added options -B and -R to the EPS driver. This enables the user to
	  clip out a region for display in the EPS file. Very convenient when
	  using xfig via pstoedit as a postprocessor of ps files and one wants
	  to maintain the preview of the file in lyx. See the man for additional
	  information.  From Morten S. Nielsen <msn@ipt.dtu.dk>
	o New PostScript DSC directives to specify page size.  Doesn't select
	  tray, which is device dependent, but works better with ghostscript,
	  ghostview and other PostScript interpreters.  
	o fig2dev now includes all "special" (LaTeX) texts that don't have any
	  backslashes ("\") in them in the bounding box.
	o genepic and genpictex drivers updated for I18N (internationalization)
	  From T. Sato
	o Glyphs for Hungarian, Polish, Romanian, Slovak and Slovenian
	  are essentially the same as Czech (ISO-Latin 2) so symbolic links are
	  created for those .ps files (hu_HU.ps, pl_PL.ps, ro_RO.ps, sk_SK.ps
	  and sl_SI.ps are linked to cs_CZ.ps)
	o fig2dev prepends any path included in the .fig filename to imported
	  image file paths (only if imported image path isn't already absolute).
	o transfig now reports when it is renaming an existing makefile or TeX
	  macro file to a backup (e.g. Makefile to Makefile~)
	o now uses Thomas Merz' jpeg2ps for imported jpeg files when exporting
	  to PS/EPS.  This is much more compact than the runlength encoding
	  which is used for other bitmaps.  Many thanks to Thomas for his
	  permission to use jpeg2ps.
	o New option for binary CGM export. The ralcgm program is required for
	  this option.  See ftp://ftp.cc.rl.ac.uk/pub/graphics/ralcgm/
	o New -E option to set encoding for pictex, latex, pstex_t and epic
	  text to ISO8859-1 (the default) or ISO8859-2
	o Added "install.all" option to make to install man pages in addition to
	  executables etc.
	o If output file ends in ".fig", fig2dev prints error message to stderr
	  and exits.
	o New encoding option (-E) for ISO-8859-1 or ISO-8859-2 from Tomas Kopal
	o Exporting to tk now supports imported PPM images in addition to GIF
	  and XPM
	o Comments added to EPS and PostScript output so MetaPost can group parts of
	  figure according to depths.  From Klaus Guntermann.
	o New -F, -R and -t options for epic output (do "fig2dev -h" for info).
	  From Gabriel Zachmann.

BUGS FIXED
	o When importing multiple GIF or PCX images, fig2dev would segfault on
	  Linux.  This happened for two reasons: the GIF file was closed and
	  reopened, which would result in a different file structure being
	  closed by the calling routine, and a palette was being allocated for
	  the PCX image and never used.
	o In multi-page mode for PDF export, figure was shifted up too far.
	o The color gold was in the wrong place for LaTeX special text.
	o Various extraneous variables removed
	o In multipage mode (PostScript export), if the figure is smaller than
	  0.1 page, nothing was generated or printed.
	o When exporting to EPS, the multipage flag was not cleared after
	  reading the file (options are set before reading file).
	o Bug in the -D option (export or exclude certain depths) where it
	  wouldn't accept 0 as a depth specifier.
	o Extra "char *c" definition in fig2dev/dev/readeps.c
	o Possible data type problem with result of floor() in readeps.c - now
	  coerced with (int)
	o fig2dev would sometimes emit the "transparentimage" for JPEG images
	  (it's only for GIF with a transparent color)
	o Minor adjustment made in tk driver which fixes problem where objects
	  extend beyond the canvas, when the objects are very far away from the
	  origin (50 inches or more)
	o Line join was not explicitely set to "miter" and line cap was not set
	  to "butt" explicitely at the beginning.  This caused problems if the
	  figure was imported into another figure because settings from
	  importing document were used
	o PNGINC Imakefile variable wasn't used
	o Minimum length (MIN_LEN) for "LaTeX short lines" was calculated
	  incorrectly (was using 13 pixels instead of 13 points as per Lamport)
	  Also, actual length of line was compared instead of horizontal
	  component (or vertical component for vertical lines)
	  Fixed by Jacques Lefrere
	o The lines in three patterns: 45 degrees left, 45 degrees right and
	  45 degrees crosshatch were too close together compared to the xfig
	  (on-screen) version
	o Pagesize may have been one pixel too small when exporting to PDF
	o Text font sizes for latex, pic and tpic output were incorrectly scaled
	  for metric Fig files (their units are points, not inches or cm)
	o Added "&& !defined(__CYGWIN__) && !defined(__DARWIN__)" to declaration
	  of sys_errlist[], errno and sys_nerr.  The __DARWIN__ is for Mac OSX
	  using X.
	o Font size was incorrect for CGM output when exporting Fig 2.x files
	o Bug introduced in 3.2.3d shifted rotated imported pictures
	o Missing % from \end{picture} in generated latex code. This caused bad
	  extra spacing when the generated file is \input into a minipage or a
	  framebox, for instance.
	  Fix from Matthias Koeppe
	o Not really a bug, but the text() proc in fig2dev/dev/gengcm.c was
	  renamed to cgm_text because of a bug in IBM's compiler which turns
	  text() into a .text assembler directive
	o Options (fig2dev -h) incorrectly had "-p name" for pstex options
	  instead of pstex_t
	o Updated language options in transfig to current set in fig2dev
	o Incorrect adjustment of scale and canvas offset for tk and ptk
	  (perl/tk) export
	o In the PIC driver, the macro PICFONTMAG should return int, but was
	  returning double, which then trashed following arguments to fprintf.
	o Extraneous semi-colon (;) after closing brace } and/or empty default
	  case (no trailing semi-colon) causes HP ANSI compiler to complain
	o Moved landscape rotation of page and Y-flip scaling inside
	  %%BeginPageSetup %%EndPageSetup block according to DSC, which says
	  that page orientation code should be there.
	o ANSI style prototype for rgb2luminance did not match proc declaration
	o When a compound object included lines that have arrowheads and large
	  coordinates (>= 100000), an incorrect bounding box was produced.
	  This same bug was in xfig 3.2.3d and earlier.
	o Output file was being closed twice in CGM and PDF driver, causing
	  segfault on some systems.
	o In the eepic driver, the thickness of a line may be incorrect if it a
	  has backward arrowhead of different thickness.
