Changes since previous package:
Chemtool-1.6.12 (June 7, 2009)
This release contains another round of fixes for label positioning
and clipping of bonds around labels. The pen color button has been
replaced by a drop-down menu, and a "white" pen for drawing on
colored backgrounds has been added. Chemtool now automatically
resizes its main window on small (netbook) screens, and it can also
be used in an non-interactive mode to create postscript (etc.) output
from previously created chemtool structure files. The Polish
translation has been updated, and a new Bulgarian translation
has been added.
Chemtool-1.6.11 (August 26, 2007)
This release contains numerous fixes for label positioning and
sub/superscript kerning. Bond length and zoom factor are now
stored with the drawing, bond clipping of multiple bonds was
improved and new special key sequences for circled plus and
minus symbols were added. The configuration dialog now lists
gtklp among the supported print commands. Source layout and
build system were reorganized to make addition of translations
easier, and a Portuguese localization file was added.
Chemtool-1.6.10 (April 8th, 2007)
This release adds PNG export, round brackets, text output in
east-european locales and some new templates. Several bugs
related to special character handling in GTK2, screen display
of labels and exporting to EPS and SVG have been fixed. The
configuration dialog has been redone and now includes support
for kprinter, and the labeling shortcuts no longer interfere
with GTK's menu accelerators.
PKGLOCALEDIR and which install their locale files directly under
${PREFIX}/${PKGLOCALEDIR} and sort the PLIST file entries. From now
on, pkgsrc/mk/plist/plist-locale.awk will automatically handle
transforming the PLIST to refer to the correct locale directory.
This release fixes a bug i(crash on startup) that was exposed by gcc 4.
It also adds detection of the recently released OpenBabel 2.0 and the ability
to use Openbabel for exporting to foreign file formats. Subscript encoding in
the SVG export was tweaked again to work around current limitations in the SVG
support of Firefox 1.5 and Konqueror 3.x.
- Fixed several serious bugs related to label rendering and printing
that occured when chemtool was built with GTK 2 instead of GTK 1.2
(see ChangeLog for details)
- SVG export now adds a namespace header as required by current builds
of the firefox browser
- SVG export now uses color values instead of color names for better
SVGT compatibility
- The separation between the lines of multiple bonds is configurable
- The keys of the numeric keypad now create two dots instead of a line
for free electron pairs when the Shift key is pressed
- Two new bond types for drawing filled and unfilled p orbital lobes
- chemtool now checks for fig2sxd (sourceforge.net) and offers to export
to OpenOffice Draw format when it is present.
- rpm packages did not install the dutch locale file.
Chnges 1.6.6:
- Fixed bug in molfile preview that caused an immediate crash in 1.6.5
- Made drawing of wiggly bonds work again
New features in chemtool 1.6
- universal import mode based on BABEL (both openbabel and babel supported)
- Formula weight calculator now handles all main group elements and the first
row of transition elements, and accepts greek phi as phenyl substituent.
- Movable hexagonal or square grid backdrop
- Improved SVG export, optional preview bitmaps in EPS export, optional EMF
export
- Cursor key support for pixel-precise drawing and moving
- The cleanup function now corrects bonds that deviate from ideal
horizontal or vertical orientation by a single pixel
- Color support (bonds and text can be red,green,blue,cyan,magenta or yellow).
- Default bond length now configurable, additional grid positions at two and
three times this length added
- Added a brief help text to accompany the 'About' window in the 'Help' menu.
- Added alternate text font (Times Roman)
- An attachment site can be marked before saving a molecule or fragment,
which act as reference point for adding this fragment to other molecules
(previously, this had to be the first atom in a file). Attachment sites are
marked in the preview window by a small x.
- Background color can now be chosen for screen display and EPS export, and
drawing whiteout boxes under labels is now an option ( off by default !).
- Text at 8,10,12,14,17,20 and 24pt can now coexist in a drawing.
- Increased allowed label length to 100.
- Improved rendering of dashed wedge and dotted lines
- Improved text kerning in xfig-based print and export.
- It is now possible to place an auto-incrementing counter at the cursor
position for numbering sites.
- Changed double bond drawing code to no longer switch sides depending
on drawing (or rotation) angle. (As a result of this, some older drawings
will need fixing)
- Rescaling a molecule now also scales its labels. Downscaling beyond
zero size (causing strange inversions) is no longer possible.
- Renamed the "Orbitals" template menu to "Symbols" and added "plus",
"minus" and a rearrangement arrow to it.
- Added two new bond types, a triple bond with all three lines equal,
and a quadruple bond.
