July 13th, 2004 ivtools-1.2.1
Two crashes discovered and fixed by Michal Palczewski (mpalczew at
users.sourceforge.net). One was a crash on exit after a delete with
idraw/drawtool, the other was a crash upon delete with graphdraw.
They turned out to be long-standing bugs in the order of object
deletion, problems that hadn't appeared with other versions of gcc.
RedHat must have adopted a more aggressive recycling of freed space in
a recent release. Thanks Michal.
June 3rd, 2004 ivtools-1.2
ivtools-1.2 sets a new direction for the package, toward peer-to-peer
drawing chat. ivtools' drawserv, the editor that incorporates every ivtool
mechanism to date (multi-frame, graph-editing, integrated scripting
language) has been extended to support a unique kind of
small-granularity shared whiteboard.
This work was based on the pre-existing networked scripting capability
of ivtools' comdraw. Then the pasting of any graphic was intercepted,
and the graphic serialized into a command that could be communicated
to other drawing editors to keep them in sync.

Changes:
November 26th, 2002 ivtools-1.0.7
- fixes for compiling with gcc-3.2 using ACE (on RedHat 6.2)
- new comdraw funcs submitted by Secil Ugurel:
- migrate glyphs/text-editor to stand-alone ivtext.
- add Quit option under File menu to ivtext..
- preliminary support for SVG export. For those interested in playing
along at home, ivtools now supports export of line graphics via SVG,
with support for variable widths, colors, and dash-patterns, as well
as rectangle export with fill colors that are blends of foreground and
background (plus none fill).
- refactor OverlayPS::idraw_format to be a pair of set/get methods
where the get method overrides the internal static member value
(_idraw_format) with the value of an idraw_format flag on an
associated Command if there is one, either OvExportCmd or OvPrintCmd.
- the export dialog box now defaults to everything if nothing is selected
in the drawing editor.
- fix drawserv attribute expression propogation used for Null
Convention Logic emulation (http://www.theseus.com).
- a new version number 13 for the idraw format adds support for
executable fonts (as opposed to static fonts). Required by recent
versions of RedHat Linux.
- fix out-of-order destruction of member objects of the central
Unidraw object at program termination.
- disable use of X11 shared memory extension for MacOS X. This may
only be a problem with 10.1, or only be a problem with XFree86 4.2, so
it may be reinstated in the future.
- customize iostream include files for MacOS X Jaguar (10.2), to mask
the difference between Apple's version of gcc-3.1 libstdc++ and
everyone elses. This is untested, so let me know if it worked for you.
- apply diffs generated by Ben Hines in creating a fink package for
Jaguar (MacOS X 10.2)
August 2nd, 2002 ivtools-1.0.6
- more changes for compiling with gcc-2.96 on RedHat 7.*
August 1st, 2002 ivtools-1.0.5
- various compile time fixes for Solaris and Cygwin.
- a proper fix for handling non-idraw PostScript. An improper fix was
introduced in ivtools-1.0.3 that made all idraw format files get
filtered through pstoedit (if you had it). Pointed out by Todd Gruhn.
- changes required to compile ivtools with gcc-3.1. Most all in the area
of migrating from use of an fstream constructor that accepted a FILE*
to use of a derivative class (__gnu_cxx::stdio_filebuf<char>) that does
the same. Wrapped up the difference between 3.0.* and 3.1 by
conditionally defining a fileptr_fstream in src/include/ivstd/fstream.h
to filebuf for 3.0.* and __gnu_cxx::stdio_filebuf<char> for 3.1.
** Constant evolution of the behavior and API of filebuf has been the
single most challenging aspect of keeping ivtools compiling with gcc
and working for the past decade. I really hope things will be stable
for the next decade. **
- fixes for using ACE and ivtools with gcc-3.1
- fix up compiling with ACE using less than gcc-3.*
- disable incremental display while incrementally loading from a URL.
A placeholder raster still gets inserted before the connection is
established, and the rest of the download and display is asynchronous,
which avoids hanging on a net connection.
- compilation fixes based on feedback from Gregory Kriehn. Mostly
adding #include <string.h> where missing. Don't know why this wasn't
a problem in every environment. Should improve support for RedHat 7.*.
June 21st, 2002 ivtools-1.0.4
- give special meaning to a set of parentheses that proceed the
tuple operator ",", by adding an extra level of nesting to the
resultant list. Before the expression "(1,2),(3,4)" yielded
"{1,2,{3,4}}". Now it yields "{{1,2},{3,4}}" as one might expect.
This anomaly stemmed from the fact the tuple operator "," works
by concatenating its right-hand argument to its left-hand argument
if the left-hand argument is already a list (that's how the
interpreter concatenates a compound tuple-expression, i.e. "1,2,3,4").
- fix unitialized variable used when reading from sockets that would
cause a hang.
- add comterp commands for the value of PI (pi), converting radians to
degrees (radtodeg), and converting degrees to radians (degtorad).
- add new matrix transpose command (xpose), which takes a 2d list of numbers
(i.e. a matrix), and transposes them.
- add a matrix addition capability to the comterp "+" operator.
- add matrix multiplication to comterp "*" operator.
- extend matrix multiply to support vector inputs.
- add support for panning with cursor keys (left/right/up/down) as well
as Page Up and Page Down (PgUp/PgDn) for larger vertical moves.
- greatly improve the efficiency of rendering alpha-transparent
rasters with a TrueColor visual. Prior to this each input color was
being looked up in a table that could be as long as 2 to the 24th,
then the weighed average computed in floating point, then the result
rescaled into a TrueColor color. Now everything is done with nothing
more than 32 bit integer multiplies, adds, and shifts. Performance
has gone from a multi-second lag to adequately interactive.
- rename "Custom Tools" to "Extra Tools".
- migrate Attribute, Annotate, and GraphicLoc to "Extra Tools".
- add a :next flag to comdraw's import func. It attempts to
auto-increment the numerics in the last URL and import again.
- sync with diffs from latest Debian release (ivtools-0.9.2-6).
- add gcc-2.96 warning to INSTALL and README files
- remove installation of extraneous scripts when non-local install.
- save/restore raster alpha-transparency value in drawing documents.
- create AlphaTransparentCmd and make available under Edit/"Image Processing"
- create raster peek command for comdraw (RasterPeekFunc).
