bondLength Lenght of bond in pt. 28
bondLengthVisible Show (true) or hide (false) bond length labels false
bondSpacing Double bond spacing in C-C bond length units: spacing 1.54 Å = spacing * scale pixels 0.18
chargeWithCircle Charge label (plus or minus sign) is displayed circled(true) or normal(false) false
chiralitySupport When to show atom chirality (R/S). off - never, selected - if a chiral flag is set for the molecule or the atom's enhanced stereo type is absolute all - always, allPossible - show all chiral centers and highlight possible but undefined centers too off
circledChargeFont Circled charge labels font: any of the fonts installed on the machine Deprecated, will be removed by January 1st, 2016. SansSerif
