Summary
Returns all text string objects whose BarCode Y Margin property complies with the Query.
Syntax
BarCodeYMargin : Number
Number will follow the measurement units currently employed for the document – either Imperial (mil; 1mil = 0.001inch) or Metric (mm; 1mm = 0.001meter).
A specific option for the measurement unit can be specified – overriding the default units specified at the document level – through use of an additional measurement unit-based keyword:
AsMils(BarCodeYMargin) : Number– to specify a margin in mil.AsMM(BarCodeYMargin) : Number– to specify a margin in mm.
Example Usage
BarCodeYMargin = 20
Returns all text string objects that have a BarCode Y Margin property which is equal to 20 current measurement units.
BarCodeYMargin >= 50
Returns all text string objects that have a BarCode Y Margin property which is greater than or equal to 50 current measurement units.
AsMils(BarCodeYMargin) > 40
Returns all text string objects that have a BarCode Y Margin property which is greater than 40mil.
AsMM(BarCodeYMargin) Between 0.5 And 0.89
Returns all text string objects that have a BarCode Y Margin property which is greater than or equal to 0.5mm and less than or equal to 0.89mm.
BarCodeYMargin <> 20
Returns all text string objects that have a BarCode Y Margin property which is not equal to 20 current measurement units.
AsMils(BarCodeYMargin) <= 15
Returns all text string objects that have a BarCode Y Margin property which is less than or equal to 15mil.
AsMM(BarCodeYMargin) < 1.23
Returns all text string objects that have a BarCode Y Margin property which is less than 1.23mm.
Tips
- The BarCode Y Margin property is only defined for text string objects.
- Use of this keyword will also return the text string child primitive objects of group design objects (component, coordinate, dimension, drill table, and layer stack table objects), whose BarCode Y Margin property complies with the Query. Should you wish to target solely text string objects that have been configured as barcode text, use an additional keyword prefix to target those objects. An example query expression would be IsBarCodeText And (
BarCodeYMargin = 20).
