LabelAlignment Property

CDXML Name:LabelAlignment
CDX Constant Name:kCDXProp_LabelAlignment
CDX Constant Value:0x0705
Data Size:INT8
Property of objects:kCDXObj_Text
First written/read in:ChemDraw 4.0
Required?No

Description:

The alignment of the text with respect to the node position.

ChemDraw reads and writes this property only for multi-attached atom labels. This property stores a value that indicates what the actual label alignment for a non-multi-attached atom label would have to be to match the desired alignment of this label. Consider an atom label with Automatic alignment, positioned on the right side of a molecule. If this label becomes multi-attached, the alignment must "freeze" at its current (left-justified value), so that if the structure is modified (rotated, flipped, etc), the label alignment doesn't change. On the other hand, the original Automatic alignment must still be preserved, in case all but the first bond are deleted in the future, at which point the label should revert to being Automatic.

This is an enumerated property. Acceptible values are shown in the following list:
Value CDXML Name Description
0 Auto Label is aligned automatically
1 Left Label is left-aligned
2 Center Label is centered
3 Right Label is right-aligned
4 Above Label is stacked above
5 Below Label is stacked below
6 Best Label is created in the best alignment for the given bonds

If this property is absent:

The text is assumed to be automatically aligned.
