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

Patchlevel 7 (May 3, 1993)
Changes to Patchlevel 6:

NEW FEATURES:

o Vertical and upside-down text - text with angles of 90, 180 and 270 degrees
    supported. Text between those angles will be drawn with the next
    higher angle (e.g. 130 degree text will be drawn at 180 degrees).
    from Alan Richardson ([e-mail])
o message panel uses asciiTextWidget so one may select text from it
o does not ask if it is OK to write an existing file during save if it is the
    current figure file that is being saved.  Same for export.
o accelerators to Save or Load file without popping up file menu
    (default: Meta-S to Save and Meta-L to Load)
o PRINTER environment variable is used if no resource is set for
    Fig*printer*string
o if an ellipse is scaled such that the radii become equal it is "converted"
    to a circle
o ablity to change to/from imperial and metric with popup menu by hitting
    mouse button 3 in the units box (where rulers meet)
    from Paul King ([e-mail])
o new command-line parameters -userscale (resource userscale) and -userunit
    (resource userunit) which are used in the on-screen messages which
    show the current length/diameter etc.  This provides a simple way of
    doing scale drawings, e.g. 0.25 inch = 1 ft (userscale=0.25,
    userunit="ft") or 1 cm = 1 m (userscale=1, userunit="m").  These may
    be changed via the popup menu by hitting mouse button 3 in the units
    box (where rulers meet)
o new indicator button allows text flags to be viewed/set
o compiles/runs on DEC Alpha with OSF/1 now
o text widget in the print popup to pass extra parameters to print program
    (lp or lpr as the case may be)
o indicator shows the number of figures in the batch print file in print popup
o automatic on-screen generation of preview bitmap for EPS objects if you have
    gs (ghostscript) - compile with -DGSBIT flag
    from Michael C. Grant ([e-mail])
    adapted from
    Marc Goldburg's ([e-mail]) original idea and code.
o indicator in upper-left corner (under Quit button) shows current filename
o print button changes message from "print FIGURE to printer" to "print BATCH to
    printer" if there are figures in batch file
o when drawing objects or moving/adding points the length/radius/diameter is
    displayed in the message window
o feature to shift figure on page if it is off the page has been disabled until
    it can be done with option or explicit command
o added -noscalablefonts command-line option to force scalable fonts OFF
    (usually for debugging)

BUG FIXES:

o condition for OSF/1 added to use dirent
    from Dave Hill ([e-mail])
o Floating point values allowed for BoundingBox in EPS files
o if user asks for scalable fonts but server doesn't support them, xfig auto-
    matically switches to non-scalable fonts
o when printing to batch file, incorrect filename appeared in message panel
o undo of a text move didn't redraw the text
o <unistd.h> included unnecessarily in f_util.c (X11/Xos.h includes it if
    necessary). Also, various cleanups with multiply defined cursors etc.
    From Casey Leedom ([e-mail])
o internalborderwidth resource should be integer not float
o cancel when drawing latex line left unwanted garbage on screen
o put_fmsg removed and put_msg uses varargs now so MIPS machines and others
    should all work fine now
o writing X11 bitmap still had bugs
o text wasn't being rotated around mouse point with rotate mode
o when moving end points of a (sp)line or when adding points to the end
  of a (sp)line, the angle geometry button was not available
o export directory now follows file directory when load/save figure is done
o entering centered text with odd number of characters caused double image
o fixed bug with incorrectly placing text with point positioning on when the
    text was originally created with point positioning off
o when moving centered or right-justified zoomed text grab point was shifted
o rotated ellipses panned incorrectly
o centering/flush-left options in Export menu were reversed
o flipped EPS objects weren't being flipped properly when reading in figure
o GC's weren't being freed when xfig finished
o added Titan OS (Stardent) to list of machines needing getenv() and atof()
    explicitely defined (not in /usr/include/... file )
    from Joachim Wiesel ([e-mail])
o underscores weren't showing in text line in popup edit
    from Daniel Faigin ([e-mail])
o old text outline wasn't being erased
    from Daniel Faigin ([e-mail])
o number[] array wasn't large enough for new 3-character numbers in the rulers
    from Andrew Haylett ([e-mail])
o check for X_NOT_STDC_ENV reversed in fig.h for inclusion of stdlib.h and
    defs of getenv() and atof()
    from Jonathan Kamens ([e-mail])
o SetDir() parameters added (but not used) to placate certain compilers
o point positioning resolution wasn't available with add-point-in-object
o angle geometry indicator appeared when moving/adding points but isn't used
o problem fixed with file popup and grab
    from David Brooke ([e-mail])

Changes to Patchlevel 5:

NEW FEATURES:

BUG FIXES:

o typo in man pages with menu item "Textyl \special commands" in export menu
o action changed from "cancel" to "dismiss" for print menu accelerator
o bug in Intrinsics? on Sun Monochrome prevented side ruler from scrolling

NEW FEATURES:

o support for two button mouse - use META + Button 3 to simulate button 2
    from Lars Berntzon ([e-mail])
o new resource "textoutline" (class "TextOutline") and command-line argument
    "-textoutline" which will outline text in red to show the bounding box
    that the text will occupy when printed (useful for rotated text)
o print popup stays up until dismissed - can still pop up file/export menues,
    draw etc. while print popup is up.  HOWEVER, while file or export
    popups are up, the print panel is not active.
o can align all objects to canvas, not just to compound - use mouse button 2
    idea from Jon Forrest
o ellipses may now be rotated by an arbitrary angle and show their rotation
    from Janes Tough ([e-mail])
o new -iconGeometry command-line argument
o new command-line argument and resource -exportLanguage to specify default

o more cleanup with respect to procedure/variable types/casts
    from Don Sharp ([e-mail])
o fixed text bounds calculation to take into account any rotation when reading
    in figure from a file to decide whether to shift figure to keep on
    canvas
    (fig2dev 2.1.5 is also fixed so figures with rotated text near edges
    should center properly now)
o fixed bug where segments disappeared while drawing interpolated spline in any
    LaTeX drawing mode
o rearranged a-z and A-Z keys in the CompKeyDB file because some HP computers
    were apparently doing random things with capitalization
    from Anthony Shipman ([e-mail])
o fixed export of color figure to X11 bitmap format.  White -> white, all other
    colors -> black.
o removed apparently unnecessary translation from w_export, w_file and w_print
    which causes coredump on some HP machines.
    From Alfred van der Hoeven ([e-mail])

    compilers to segfault
    From Alfred van der Hoeven ([e-mail])
o new environvemt variable "XFIGTMPDIR" used for xfig temporary files directory
o when reading a figure file, if any object coordinates are negative, the figure
    is shifted to keep it on the canvas so that the upper-left corner of the
    figure is placed on the current point positioning grid
    (in 2.1.4, the upper-left corner was placed at 10,10)
o changed "char" to "unsigned char" for initialization of bitmaps by compilers
    from Teus Hagen ([e-mail])
o was passing floats to put_fmsg() instead of doubles.
o includes copy of X11/Xfuncs.h now to use correct routines for zeroing/copying

    CompKeyDB (multi-key) database file in the standard X11 library
o fixed bug introduced in 2.1.1 which incorrectly placed radius marker of
    circles created by radius
o circle is now changed to ellipse type when scaled assymetrically
o fixed various typos in xfig.man
o changed references to mouse buttons left/middle/right to say buttons 1/2/3
    respectively
o radius of ellipses-specified-by-radius was one pixel too large
o changed interpretation of 1/0 bits in EPS preview bitmaps back to original
    0=white, 1=black according to EPSF guide version 2.0.
    Brought to my attention by Vivek Khera ([e-mail])

    to $XFIGLIBDIR
    from Pete Kaiser ([e-mail])
o simple edit arrowhead feature in the popup edit for lines - can add/delete
    arrow heads.  No adjustment of arrow size yet - uses current linewidth
    from indicator panel
o Example figure files have all been converted to 2.1 file format
o if any object coordinates are negative, the whole figure is shifted to keep it
    on the canvas
o fixed major bug where the preview bitmap of EPS objects was in reverse video

    up respective menus used incorrect options
o changes to the file popup:
    o new "Home" button changes directory to $HOME
    o ~ (username) operator allowed in the current directory ascii widget
    o new label widget shows the current figure filename
    o presssing "Load", "Save" or "Merge Read" will operate on the
      filename in the "Filename" window.  If that name is empty the
      operation is done on the file specified in the "Current Filename"
      window.
    o additionally, the "Load" operation will copy the name (if any)
      from the "Filename" window to the "Current Filename" window
    o pressing return in the "list of files" window in the popup File panel
      will "Load" the file
o changes to the export popup:
    o new "Home" button changes directory to $HOME
    o ~ (username) operator allowed in the current directory ascii widget

    the screen)
o If you have Display Postscript in your server, compile xfig with -DDPS
    and you will see the full Postscript object instead of preview bitmap
    when you include EPS objects.
    !!! WARNING: this has only been tested on IBM's AIX 3.2 (X11R4) on
    an RS/6000 !!!
    from Dave Hale ([e-mail])

o unused function clear_char_string() deleted from w_canvas.c
o current depth is now in an indicator window and may be set like line
    thickness, color etc.
o added update tags to control which object components are modified/copied
    when using the update button.  Button appears in upper-right corner
    of indicator button (e.g linewidth) when in update mode.  Clicking
    on the update tag enables/disables components (e.g. linewidth) from
    being copied to/from objects when using update.
o fixed exporting of pstex_t and pstex (used to give Postscript for both)

Changes to Patchlevel 2:

o pressing carriage return in value part of popup indicator buttons that take
    integer or float (e.g. line width) now sets the value and pops down
o added foreground colors to Text*, Menu* and List* widgets in default Fig-color.ad
    this fixes problem of white-on-white text when using inverse video

    from David Elliot ([e-mail])

------------------------------------------------------------------------------
Patchlevel 2
Changes to Patchlevel 1:

o the font flag (LaTeX, PostScript) wasn't being changed correctly in the
    UPDATE text object operation when switching from LaTeX to PostScript
    or vice versa.

o the textstep value may now be entered in floating point in the popup menu

o the eps-bitmap icon was renamed to eps-object because it can be any
    eps object that is imported.  If it has a preview bitmap
    that will be displayed.  Several filenames/program variables
    were also changed to reflect this.

o there is now a more general glue mechanism for compounding objects

o text pasting into canvas now possible with F18 function key or any translation
    desired by user.  F18 is hardwired default in program; F20 also
    programmed in Fig.ad to paste text.
    Brian Boyter (pyrdc!bimbo![e-mail])

o DEFAULT fill_style caused core dump
    from Jeffry R. Abramson ([e-mail])

o made the mouse-tracking markers hollow so as not to be visually obtrusive
    as suggested by Stephen Gildea ([e-mail])

o cleaned up gcc compiler warnings about type mismatches etc.

o compound objects may be rotated by arbitrary angles if there are no boxes,
    arc-boxes, ellipses or circles contained within.

o text rotation support is improved - markers are now shown rotated and
    the angle attribute is set by the relevant rotate operations.

o both ps and eps modes now supported in export menu.

o new directory browsing facilities integrated with File and Export popups.
    Allows selection of file by clicking on the filename.  Has mask to list
    only those files of interest.  See the man pages for further details.

o Default font for Postscript fonts may now be selected and objects that
    have default font may be edited

o FASTSERVER flag removed; now always uses smart redrawing when available
    Additionally, smart redrawing is available more often

o fixed bug in regular polygon where some vertices were off by one pixel

o added "Use orig. size" button for eps objects to set object to original
    size in popup edit
    from Peter Scott ([e-mail])

o international characters supported (umlauts, accents, cedilla etc) using
    compose (meta) key
    from Herve Soulard ([e-mail])

o much improved color support
    from Henning Spruth ([e-mail])

o additional pan and zoom mode with <Ctrl>Key and left/middle/right button
    from Henning Spruth ([e-mail])

o removed reference to FONTLIBDIR in Imakefile (no longer required)

o added a smart-links feature for the MOVE and COPY commands.
    With smart links turned on, when a BOX-like object is moved
    so are the lines which join up to it (its links).
    Two modes are supported: one which moves just the endpoint,
    the other slides the endlink so that it's angle doesn't change.
    In the second mode horizontal/vertical lines remain that way.

o added the ability to save figure during quit if it is modified

o added support for scalable fonts under R5

o additional command line flags supported
    -latexfonts flag (resource .latexfonts) to start xfig with the LaTeX
    fonts as the default instead of PostScript fonts
    -specialtext flag (resource .specialtext) to start xfig with special
    text as the default

o bug fixed where number of objects count in file popup was sometimes clipped

------------------------------------------------------------------------------
Patchlevel 1
Changes to Patchlevel 0:

o xfig now reads text size, height and length as floats and rounds to ints
    this is done because certain programs generate floats for these

o compound object was rounded to next larger grid even if objects inside were
    already on the grid

o Examples/logo.fig included Logo.eps instead of logo.eps

o cancellation of line drawing left single dot on screen

o filename in File popup menu didn't get set until first popup - file save
    shortcut would save to unnamed.fig even if xfig was started with file name

o bug fixed in not being able to delete points from certain objects

o typo in FORMAT2.1 file (and all previous) stating that text angle is int when
    it is really float

o can now change corners of compound object with edit popup
    also shows number of objects inside compound

o file menu now shows number of objects in figure

o some bugs fixed in calculating bounding boxes after scaling ellipses and
    compounds

o "#ifdefined SYSV" now reads "#if defined(SYSV) || defined(SVR4)" because X11R5
    doesn't define SYSV if SVR4 is defined
    David Elliott ([e-mail])

o object depths < 0 are converted to depth = 0

o typo in Adobe font name (was "-abode-new century schoolbook-medium-r-*--*")
    Jan Lindheim ([e-mail])

o radius field for non-arcbox line objects now set to -1
    Jan Nusteling ([e-mail])

o bug fixed in not trying to load an eps bitmap file called <empty>
    and not trying to reload an eps bitmap during a copy.

o bug fixed which caused crash after editing 0-width or 0-height ellipses

o bug fixed which caused incorrect mode after cancelling draw (int)spline

o bug fixed which caused incorrect minimum number of points for (int)spline

o bug fixed which caused erroneous large values to occur after box scale of
    0-width or 0-height objects.  You can no longer box scale such objects

------------------------------------------------------------------------------
Patchlevel 0
Changes to Version 2.0 Patchlevel 10:
Implemented by Paul King ([e-mail]) and
Brian Smith ([e-mail]) with help from
Micah Beck ([e-mail]) and
Brian Boyter (pyrdc!bimbo![e-mail]) (EPS code).

USER INTERFACE
--------------

o The buttons are now grouped into three panels:

    COMMAND panel:
        Quit, Delete all, Undo, Redraw, Paste, File popup, Export popup and
        Print popup buttons.  See man pages for details.
        (see "Drawing Modes", below for description of Cut)
    MODE panel:
    Allow the user to select the current drawing or editing mode.
    INDICATOR panel:
    By default shows indicator buttons relevant to the current mode.
    Each indicator button displays current setting of some quantity
    (e.g. line width, area-fill) and allows it to be changed:
        left button gives popup menu to select setting,
        middle/right buttons provide a shortcut to inc/decrement settings.

o Pan figure by using left/middle/right button in the rulers in addition to
    the previously supported arrow keys.  Also a pan to origin operation
    is available by clicking in the units window (or using HOME key).

o May now print figure that hasn't been saved (i.e. print what is on the
    canvas, not the file)

o Zoom up or down with zoom button.

o Mouse function window shows function of active buttons

o New resources/command-line switches which affect the user interface:
    -showallbuttons        (show all indicator buttons all the time)
    -internalBW n        (use lines of width n between buttons/panels)

DRAWING MODES
-------------

o Regular polygon drawing button - select number of sized from bottom panel.
        Object created is normal xfig polygon.

o Inclusion of Encapsulated Postscript files (bitmap image in EPS file is
    displayed).

o Rubberbanding of ellipses/circles.

o Filled splines show areafill on screen now
        also dashed/dotted line type shows on screen

o Dot-gap and dash-length can be changed in the line-style indicator popup.

EDITING MODES
-------------

o Cut to buffer operation is now part of Copy object mode & Delete object mode.

o Update button to either update objects to current settings, or update
        indicator settings from an object.

o Rotation of certain objects by any angle (30, 45, 60, 90, 120 degrees can
    be selected using the mouse middle/right shortcut buttons).

o Alignment horizontally and/or vertically of objects to compound object edge(s)

o Objects can be scaled (not just compounds).

o Point move or object copy/move constrainable to horizontal or vertical
    movement (middle mouse button)

o Compound bounding corners shrink to fit enclosed objects and have markers
    that appear the same as other objects.

o Shift-click selection should work on all editing operations.

o Only the objects relevant to a particular editing operation will
    have their markers shown.

OVERALL OPERATION
-----------------

o Smarter redrawing (if compiled with -DFASTSERVER).
    Only the relevant objects are redrawn after an expose or after
    an edit operation (not all operations support this yet).

o Undo should work for all commands.

o Operations can now be cancelled (using the right button when appropriate).

o Point positioning to three resolutions:
    magnet (1/16inch), small grid or large grid

o TransFig 2.1 features: LaTex fonts, hidden text, scalable text, "special" text
        see TransFig man pages for description
        scalable text sizes with resizing of figure

o Attempts to save figure if signal detected (segmentation violation, etc)

o Resizing the xfig window should now be a bit smarter.

o The philosophy behind button usage has changed. This was necessary to
    provide a consistent (as possible) philosophy which supports the
    use of several buttons per mode.  Now the same button used to start
    an edit/draw operation is used to continue to the normal next step
    in the operation.  The right button can be used to cancel an operation.
    Watch the mouse function window until you get the hang of it.
