OEDepict TK 2.2.5

New features

• OEImage allows users to easily rescale images without having to re-render all the drawing commands.

• OEPrepareDepictionOptions.SetDepictOrientation allows users to control the preferred orientation of the 2D coordinates. This allows optimizing 2D coordinate generation for a particular orientation: horizontal, vertical, or square. For example, OEDepictOrientation_Horizontal should be preferred when vertical space is expensive, as on web pages and spreadsheets.

• OEHighlightByStick.SetAtomExternalHighlightRatio has been added to generate better highlighting for very small images. See the image in the OEHighlightByStick.SetAtomExternalHighlightRatio documentation for an example.

• OEConfigurePrepareDepictionOptions provides a convenient way to translate command line parameters into options on a OEPrepareDepictionOptions object. All OEDepict TK examples have been updated to use these functions for building consistent command line interfaces. See the examples in the OEDepict Examples Summary section.

• OEGetCenter and OEDrawTextToCenter are convenience functions added to ensure that text is drawn vertically and horizontally in the center of an OEImageBase.

• Two new pens, OELightGreyBoxPen and OELightGreyPen, have been added.

Major bug fixes

• OEPrepareDepiction now automatically regenerates 2D coordinates when the current 2D coordinates are not in the XY plane. OEPrepareDepiction now clears coordinates when any of the following conditions are true:

  • OEPrepareDepictionOptions.GetClearCoords returns true.

  • OEMolBase.GetDimension does not return 2.

  • Any Z coordinate is not 0.0.

  This protects against corrupted coordinate states that may be caused by file formats not normally used for depiction, such as PDB.

• PNG images generated on Linux will now have properly filled objects and will no longer look different than those generated on OSX or Windows, as shown in the following images:

• The cubic and quadratic curves drawn on OSX PNG images are no longer closed and are now consistent with PNG images generated on other platforms.

• PDF files should no longer cause the following warning message when read into Adobe Acrobat:

  The font "Times" contains a bad/BBox.
  

Minor bug fixes

• A new OE2DMolDisplay.IsValid method has been added. A molecule display is considered valid only if it was initialized with a non-empty molecule with either 2D or 3D coordinates. An invalid molecule display cannot be rendered by the OERenderMolecule or the OERenderMoleculeToString functions.

• The OEHydrogenStyle_Hidden style will no longer show any hydrogen labels, even if the hydrogen has a charge, isotopic mass, or is a radical.

• The OEAnnotateDepictionProblems function now displays E/Z CIP bond labels rather than C/T in cases where double bonds are not correctly depicted according to their cis/trans stereo specifications.

Documentation changes

• All images in this documentation were automatically regenerated to reflect the changes made since the previous release.
