Fixes and enhancements in chemtool 1.6.9 - Fixed placement of right-justified labels containing sub- and/or superscripts on screen and in all XFig-based export modes. - Worked around a bug in fig2dev that prevented creation of EMF files - Improved spacing of sub/superscripted labels in GTK2 builds - Corrected line spacing of triple and quadruple bonds. Fixes and enhancements in chemtool 1.6.8 - Fixed an ugly bug that could crash the program on startup, especially if it was compiled with gcc 4.0.x - Chemtool now recognizes OpenBabel 2.0 - Added a new Export function for exporting through openbabel - Modified sub/superscript text in SVG export to work around limitations in the current vesions of firefox and konqueror. Fixes and enhancements in chemtool 1.6.7 - 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. Fixes and enhancements in chemtool 1.6.6 - Fixed bug in molfile preview that caused an immediate crash in 1.6.5 - Made drawing of wiggly bonds work again Fixes and enhancements in chemtool 1.6.5 - Added a Dutch translation (Myckel Habets) - Added import ability of V3000 molfiles - Added SDF file browsing/import support and molfile preview - Fixed atom name justification in the builtin MDL molfile export function and added proper translations for XH_3, XH_2, XH labels. - Fixed the builtin molfile import function to tolerate optional property blocks - Made building without locale (national language) support work again - Made building with the old, menuless user interface work again - Fixed non-portable syntax in the configure script Fixes and enhancements in chemtool 1.6.4 - Aminoacid sidechain and backbone templates. - Arrowheads of curved arrows no longer grow out of proportion. - Improved positioning of sub- and superscripts to match the screen display - xfig compound and optional whiteout box now cover sub- and superscripts - Corrected placement of non-subscripted left-justified labels - Latex symbol translations for degree, plusminus and copyright sign. - Cleaned up X11 font dependencies to be either 75 or 100dpi, not both. - Added KDE directory install targets to the Makefile to allow installation to a temporary directory (Debian-like installations mainly). - chemtool now compiles with GTK 2.x if it is available (this offers the potential for non-western localisations). Fixes and enhancements in chemtool 1.6.3 - Chemtool should now build and run cleanly on 64 bit systems and OS X - Sum formula/molecular weight program now handles the second and third row of transition elements. Fixes and enhancements in chemtool 1.6.2 - Right justified labels are no longer offset by one character position when the drawing is exported. - It is now possible to move bonds by dragging them in 'Move' mode without first having to mark them as a fragment. - configure now searches for KDE in /opt/kde3 and /opt/kde2 as well. Fixes and enhancements in chemtool 1.6.1 - chemtool should now work equally well with either the 75dpi or 100dpi XFree86 raster fonts (1.6 absolutely required the 75dpi fonts) - improvements to bond pruning underneath labels - better positioning of right-justified labels, better clipping limits around labels - better formatting of labels containing parentheses - syntax fixes (missing $s) for greek/special characters, and proper escaping of isolated percent and dollar characters in Latex export. - various improvements in the SVG export - support for direct entering of labels in the bond drawing modes, and improved updating of label properties - translated messages were truncated in some cases in 1.6 - portability fix (undo memory handling) for some SGI Irix variants - Updated French and Brazilian translations - Updated documentation 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.
