Ipe 6.0 preview 16 (2004-06-05)

 * Ipetoipe was not installed.

 * Ipe could not load its own figures because of a stupid typo.

 * Fixed a bug in scissors.

--------------------------------------------------------------------

Ipe 6.0 preview 15 (2004-06-04)

 * Fixed handling of transformation matrix in Pdftoipe.  Pdftoipe
   is now actually considered supported.

 * Added option -math to pdftoipe.  With this option, all text objects 
   are turned into math formulas. 

 * Color changes in text objects (e.g. made using \textcolor) and
   quotient bars are now shown on screen.

 * Views (that is, page views) are now fully integrated in Ipe's main
   user interface. They are easier to create and maintain.

 * Views keep a record of the active layer, so that switching back to
   a view to edit it makes objects go in the right layer (usually).

 * Pressing the right mouse button in the layer list opens a context
   menu.

 * Changed handling of style-sheet stretching of text objects.  The
   width/depth/height of text objects now correctly reflects this
   stretching, and when creating a minipage object, the user drags out
   the actual desired width.  

   Unfortunately, this changes the semantics of Ipe documents!  To
   make it possible to do this change automatically, the style sheet
   tag has been renamed from <textmatrix> to <textstretch> (with
   slightly changed syntax, see the manual).  Currently, a simple
   automatic conversion is done: if the style sheet contains ANY
   textmatrix tag, the conversion factor is applied to the width of
   ALL text objects in the document.

 * Simple background shadings are now possible using <shading> in a
   style sheet.

 * Two new types of text objects defined.  They are just variants of
   label and minipage.  A new function 'Insert text object' creates
   textbox objects with fixed left and right margins (set in the style
   sheet).

 * Move-to-back function now inserts in front of anything in
   background layer.

 * Renamed the method NotifyStyle to CheckStyle.  

 * Added a simple clipping ipelet (clips only marks and line segments
   to a convex polygon - just about enough to be useful for clipping
   Voronoi diagrams).

 * Fixed bug #42 (linewidth could be null in IpeBBoxPainter).

 * Ipe remembers file format used for saving. 

 * Latex style files are now searched for both in the current
   directory and in the directory containing the Ipe document.

 * Command line option -geom WxH+X+Y (note the slight difference to
   X11, where the option is '-geometry').  Smarter zoom on opening
   documents. 

 * Simplified handling of locked layers.  A locked layer cannot be
   made the active layer now.

 * Each page stores the grid size used to create it.

 * Only one (global) media size per Ipe document.

 * Refactored Ipe program into separate model/canvas library.  
   The Ipe canvas can be reused by programs wishing to display Ipe
   data. 

 * Ipe file format conversion functionality (-topng, -topdf etc) has
   been moved into a separate program "ipetoipe".

--------------------------------------------------------------------

Ipe 6.0 preview 14 (2004-04-30)

 * Changed display of grid as requested by Sariel Har-Peled.

 * Fixed bug #40 (atan2 DOMAIN bug on zero-length segments).

 * Changed to using dynamic Borland RTL (cc3250.dll)

 * Finally libipe is compiled as a DLL on Windows as well.

 * Fixed bug #28 again, differently, and hopefully really...

 * Disabled pasting bitmaps on Windows version - Qt crashes on certain
   bitmaps (perhaps GIF format bitmaps??)

 * Fixed serious bug that stopped Ipe from opening any figure
   containing bitmaps. 

 * Fixed problem with templates not defined in current style sheet.

 * New 'templates' ipelet with simple functionality for making
   backgrounds for presentations.

 * Fixed bug #37 (Ipe now more accurately computes the bounding box
   stored in PDF output).

 * Added setting for infinite-edge length to qvoronoi ipelet, and
   fixed a crash when it is called without any sites.

 * Fixed divide by zero crash in arc drawing.

--------------------------------------------------------------------

Ipe 6.0 preview 13 (2004-04-20)

 * Official Windows Ipe distribution is now compiled with free Borland
   C++ compiler.

 * Changed license to allow linking with CGAL.

 * In preferences dialog, one can now set the initial grid visibility,
   window maximizing, default paper size, and the default style sheet.

 * Style sheets can now define LaTeX preamble pieces.

 * Command line option to add a style sheet to new document.

 * "Insert image" moved to file menu, added inserting from clipboard.
   Ctrl+V will now paste a bitmap from the clipboard.

 * Fixed bug #1 (copied text has wrong textmatrix).
 
 * Fixed display of arrows on non-solid lines.

 * Fixed bug #13 (Symbolic attributes missing in the style sheet no
   longer cause Ipe to crash).

 * XML parser slightly improved, accepts XML comments <-- XXX -->.

 * Ipe now compiles on two different compilers without warnings.

 * Invisible text objects no longer break latex run.

 * Fixed bug #28 (Ipe5toxml couldn't run).

 * Notes on changing keyboard shortcuts (thanks to Kostas Oikonomou).

 * Fixed bug #38 (horizontal text alignment not preserved when reloading).

 * Fixed bug #26 (Ipe doesn't work with fptex).

 * Fixed compilation on Solaris and other Unixes (thanks to Kostas
   Oikonomou). 

 * Improved C++ portability (thanks to Thomas J. Kacvinsky).  Ipe
   should compile with Forte C++ now.

--------------------------------------------------------------------

Ipe 6.0 preview 12 (2003-11-18)

 * Fixed bug #24: A pdfTeX/pdfeTeX mixup that stopped Ipe from working
   with MikTeX 2.4.

 * Documentation wasn't installed correctly.

 * According to Stefan Langerman, Mac OS X 10.3 changes name
   convention for dynamic libraries.  Fixed in Ipe.

 * Fixed bug #18. The directory containing the Ipe file is now
   searched for Latex style files. (When using the -topdf etc options,
   the current directory is searched.)

 * Fixed bug #20, creation of arc/circle through three collinear
   points.

 * Added feature #22 (loading and modifying files for which pdf and
   eps versions exist).

--------------------------------------------------------------------

Ipe 6.0 preview 11 (2003-11-06)

 * Patches by Stefan Langerman for Mac OS X.

 * Ipe installation automated with "make install".

 * Fixed serious problem that caused Ipe figures to crash printer or
   previewer when circles/arcs where used.

 * Fixed stroke color appearing incorrectly on screen when using
   anti-aliased text.

 * Fixed crash when snapping to intersection on zero-length segments

 * Fixed bugs in "Goodies/Precise box"

 * "Duplicate" now unselects old objects.

 * Fixed Ctrl+E leaving Ipe.

 * Fixed undocumented operator 'h'.

 * Fixed bug that caused menu to be dimmed when creating marks and
   labels. 

 * Fixed bug #11 (Ipe closes without saving file).

 * It's no longer necessary to enter an extension when saving.  Ipe
   will now use whatever is set as the filter in the dialog.

 * Fixed bug #12 (Arrows drawn with dotted linestyle).

--------------------------------------------------------------------

Ipe 6.0 preview 10 (2003-04-14)

 * Changed calls to Freetype to be less dependant on Freetype
   version.  Ipe should now work correctly with the Freetype version
   already on the system.

 * "runlatex.bat" created with CRLF

 * Support for multi-key sequences if compiled with Qt 3.1.

 * Paragraph input dialog comes up with focus.

 * Function to move objects to current layer (in Layer menu).

   sheet).

 * Copy and paste for images fixed. 

 * Copy and paste for whole pages implemented.

 * Ipe is now usable with two-button mouse (see manual section "Mouse
   shortcuts")

 * Images will only be embedded once, even if they have been inserted
   several times from the same file.

 * Using system fontmap if available, otherwise allow installer to
   specify Ipe fontmap.  See "install.txt" for instructions.

 * Style sheet dialog.

 * Anti-aliased text.

 * Can change font of Latex source input fields.

 * Zoom spinbox buttons behave more reasonably.

 * Keyboard shortcuts for ipelets possible (and used by align ipelet)

 * Copy and paste of Unicode text works now.

 * Ipe checks for not matching header files/library version for libipe
   and libfreetype.

 * Large bitmaps are rendered at lower resolution to speed up
   redisplay.

 * Reference point of text objects can be chosen, including baseline position.

 * Edit and Ungroup now available in Edit menu.

 * Ipelet/Align supports baseline alignment.

 * Pasting text creates a text object.

 * Displaying closed paths on-screen uses line-join properly now.

 * When saving a file, Ipe runs Pdflatex only if it's necessary.

--------------------------------------------------------------------

Ipe 6.0 preview 9 (2003-03-26)

 * Compression option in Preferences is now a single checkbox.

 * Function to save current page as bitmap (can also be called from
   command line as -topng).

 * Fixed behaviour when switching between absolute and symbolic
   attributes. Introduced separate switch for grid size and angle.

 * Fixed masks for toolbar icons.

 * Finished handling of images.  They are now finally embedded
   efficiently in PDF documents (that is, not once in PDF format and
   once in XML format).

 * Text objects can now be transformed (rotated, stretched, and scaled).

 * Support for magnified text in presentations (see section on Style
   Sheets in the manual). 

 * Fixed size selection of Ipe window on start-up.

 * Goodies ipelet: Function "Create mediabox" added.

 * Support for Ipe localization added. Can also be used to change the
   keyboard shortcuts.

 * Fixed origin of stretch/scale.

 * "Select all" retains primary selection.

 * Keyboard shortcuts can be configured (see section "Customizing Ipe"
   in the manual).  

 * Width of paragraph objects can be changed (in object menu).

 * Snapping functions F3 and Shift-F3 implemented.

 * In snapping functions F1 and F2, angular snapping is now off.

 * Object menu button finds near object if primary selection is far
   from mouse.

 * 'Normal size' function implemented according to Rene's suggestion.

--------------------------------------------------------------------

Ipe 6.0 preview 7 (2003-03-14)

 * Voronoi diagram ipelet

 * Invisible layers are hidden in default PDF presentation

 * Zlib no longer included in source distribution, upgraded to zlib
   1.1.4 in Windows distribution.

 * Text objects have no snapping.

 * Inserting JPEG images is now supported.

 * Inserting bitmap images compresses the bitmap (makes PDF, EPS, and
   XML files smaller).

--------------------------------------------------------------------

Ipe 6.0 preview 4 (2003-02-28)

 * First public release of Ipe 6.0

--------------------------------------------------------------------

Ipe 5.0 August 15, 1994

 * rewrote Ipe to run under the X window system, and ported to 
   HP7xx systems and Sun SparcStations.

 * the user interface is now based on Motif.

 * there are two versions of the canvas, one using gl and my
   previous code, the other using plain X calls. This version,
   however, needs to allocate a large number of color cells to
   implement an overlay plane with double buffering (which gives much
   smoother drawing).

 * added fields showing the name of the last operation and the
   keyboard shortcut.

 * the Ium interface now handles -input and -file, and is capable of
   making this persistent.

--------------------------------------------------------------------

Ipe 4.1 July 5, 1994

 * fixed bugs introduced with the transition to PLAGEO 2.0.

 * changed calling of Iums so that the same Ipe binary works under
   irix 4.0.5 and irix 5.x.

 * the windows are now redrawn while loading and saving files.

 * moved more complicated Iums out of standard Ipe distribution and
   put the documentation on my www page (the world wide Ipe home
   page), instead of in the Ipe documentation. This will make it
   easier and more convenient to update the set of Iums for non-local
   users.

 * the executable for a Ium is now required to have the file extension
   .ium.

 * the height of the bounding box shown for minipages is now computed
   through LaTeX. Only the width is part of the minipage's definition.

 * added Segments object type, to compactify Ipe files containing lots
   of strokes of the same type (which typically arise in mechanically
   created drawings).

 * fixed up manual and index.

 * added blueadj and display options for mipe.cls.

 * changed style files and documentation to conform to LaTeX2e.

 * font sizes are now defined as floats, so we can use real LaTeX font sizes.

--------------------------------------------------------------------
  
Ipe 4.0 March 8, 1994

 * the Ipe file format is now at the same time an encapsulated
   Postscript file (eps), and it can be included without any package
   support. The style file ipe.sty is now only necessary for
   scaling or other non-standard behavior.

 * Text and Mark objects can now be invisible, like any other
   object.

 * when creating a Minipage object, you first have to drag out a
   bounding rectangle.

 * when previewing a single page that does not contain any text
   object, Latex is not run anymore.

 * introduced UndoLimit configuration variable and statistics function
   (in misc menu).

 * fixed treatment of linewidth for Postscript importing.

 * made changes necessary to use PLAGEO 2.0.

 * while loading a file, the new Latex preamble is now already in
   effect. But: this is now also true when inserting a file.  After
   insertion, the preamble of the containing file is used again.  This
   may become confusing.

 * the center of the drawing is now mapped to (300bp,400bp), so that
   printing the Ipe file directly will roughly center it on a4 or
   letter style paper.

--------------------------------------------------------------------

Ipe v3.2 February 10, 1994

 * made Ipe into a ``package'' (this concerns some changes in
   our local installation.)

 * the manual is now in a reasonable shape

 * added ``Ipe user objects'', the possibility to specify an
   Ipe file as a ``user macro''.

 * added "With Prologue" button and code.

 * added arrows for splines (back). 

--------------------------------------------------------------------

Ipe 3.1 February 1, 1994

 * rewrote the spline code. Ipe now has a full spline object
   type, supports snapping to splines, and has a clearer interface.

 * the pop up bit-planes are now managed via redraw events. The
   interface is much clearer. Made colors that are used in pop up
   planes user-definable.

 * added directional snapping modes.

 * made mouse-explainer work for forms objects and with Shift and Ctrl
   keys.

 * put documentation in html document.

 * added some Ipe user macros for handling bitmaps, based on the "lug"
   graphics utilities library by Raul Rivero.

 * changed handling for calling Iums. Ipe will now redraw while
   waiting for a Ium to finish, and the ESC button can be used to
   cancel a Ium.

 * added a Ium for polygon approximation.

 * added reading and writing of raw bitmaps when communicating with
   Iums.

 * added a contour tracer for the Bitmap Ipe user macro.

 * added MakeBackups option.

 * when Ipe is killed and the drawing is not saved, Ipe will now
   save it in #unsaved.ipe#.

 * added Iums to call imged, imgworks, and xpaint.

 * "preview page" and "preview all" now use different temporary files,
   so they will not collide any more.

--------------------------------------------------------------------

Ipe v3.0 January 1, 1994

 * fixed bug in Postscript prologue that made coexistence of ipe.sty and
   epsf.sty in same LaTeX-file difficult

 * Now Ipe does not crash anymore when the Ghostscript window is
   deleted from the window manager. The next time that preview is
   called, a new Ghostscript window is created.

 * revised the handling of keyboard and menu events. They are now
   table-driven, and controlled by a single subroutine.

 * reintroduced the Zoom & Pan mode for synchronizing the Ghostscript
   window. It is much more convenient than the fully dynamic mode.

 * added a documented .iperc file format. Ipe will no longer start up
   without such a configuration file (but you can specify a different
   one using the -n flag).

 * Line widths, font sizes, grid sizes and the like are now all
   defined in the configuration file. There is no new line style
   function anymore, and no save configuration option.  All counters
   are replaced by choice objects.

 * added type-driven selection mode. If the Ctrl key is pressed when
   selecting objects with the right mouse button, only objects of the
   currently active type are considered. The same works for M-C-a.

 * added interface to Ipe user macros, and moved several rarely used
   functions and the import functions into Iums.

 * export Idraw has disappeared for the time being. I have never
   actually used this feature yet, and it's a mess, since all
   interesting pictures have some elements that Idraw doesn't
   understand.

 * wrote several pretty simple Iums based on existing plageo or leda
   code. Currently available are convex hulls, Voronoi diagrams, and
   clipping of polygonal objects.

 * revised the snapping concept, introduced priorities, and made
   peaceful coexistence of angular and boundary snapping possible.

 * Rotate, Scale, and Stretch are now available using a modifier key
   and the mouse. Their buttons have disappeared, since these
   operations are not actually object types, and there should not be
   such an ``object type.''

 * added delete function, that deletes objects without placing them in
   the cut buffer.

 * added keys C-d and r for the polygonal objects edit mode, and key
   C-d for line entry.

 * there is now a panning function. This was necessary because of the
   multi-page mode, were the template has to remain aligned with
   respect to all pages.

 * the snap to intersection point function now recognizes self
   intersections of polygonal chains. Also added a button to control
   snapping to object itself during editing and entry of polygonal
   objects.

 * added Fifi, a little marker that accompanies the cursor and shows
   the current snapping.

 * Ipe now does not crash anymore when the background Latex process
   for finding bounding boxes wants to read another file.

 * added bitmap object type, and a Ium to read in Silicon Graphics
   .rgb format files as bitmaps.

--------------------------------------------------------------------

Ipe 2.4 December 3, 1993

 * fixed bug in text yank that made Ipe crash

 * added multi-page mode

 * when undo is turned off in the configuration panel, the storage
   currently used by the undo buffer is released

 * the saved properties now do not contain a description of the data.
   If you use the edit properties function, you are supposed to what
   you are doing.

 * changed keyboard shortcuts to cohere to IES (International Emacs
   Standard)

 * changed layout of configuration form to fit better with main form

 * added configuration option to disable drawing of filled
   splines. This is much faster than the default behavior.

 * Zoom now has a logarithmic scale, and different interface.

--------------------------------------------------------------------

Ipe 2.3 August 11, 1993

 * scale and rotate now use center of object by default.

 * fixed bug in precise scale

 * added second input mode for arcs, using center of circle

 * added arrows on arcs

 * made Latex preamble for previewing and printing user-definable

 * bounding box for text objects is now computed by Latex

 * fixed two severe bugs that caused Ipe to eat up memory

 * put help information into a Texinfo file

 * made Control-middle button shortcut for scale/stretch

 * added Ghostscript previewer that runs in background

 * added importing Postscript files

 * changed all fixed limits to rerays, to make sure that arbitrary
   Postscript files that can be read won't make Ipe crash

 * allow filled non-simple polygons

 * added snapping to intersection points

--------------------------------------------------------------------

Ipe 2.2 August 1, 1993

 * added circular arc object type

 * added minipage version of text objects

 * added support for splines.

 * circles now behave properly when stretched and become ellipses

 * more color buttons, click with left and right mouse for fill and
   stroke

--------------------------------------------------------------------

Ipe 2.1 July 28, 1993

 * snapping to other objects

 * viewing and editing object properties

 * parameter form to change the configuration

 * changed layout of form

 * added icons for object type buttons

 * added field showing arrow/line style choice

--------------------------------------------------------------------

Ipe 2.0 July 14, 1993

 * This is the first version of Ipe. It is version 2.0 to distinguish
   the Ipe file format from the format generated by "ipefy".

--------------------------------------------------------------------
