Spacing Category
The Spacing category provides options for specifying line spacing for elements with a block structure. The options on the Spacing category are not available when Structure type in the Breaks category is set to Inline.
* 
Refer to Units of measurement in Arbortext Editor help for information on valid units.
The following table describes the properties on the Spacing category.
Property
Description
Default Value
Line spacing
Controls spacing between the lines in an element mapped to the Block style.
The choices are:
• <Derive> - Specifies line spacing based on system default, property set, or ancestor settings.
• Single - Sets lines to be single spaced (1.1 em).
• 1.5 lines - Sets lines to be halfway between single and double spaced (1.65 em).
• Double - Sets lines to be double spaced (2.2 em).
• Specified - Sets line spacing to the value specified in the At field.
* 
Setting the value of the At field to the em values associated with the defined types of line spacing resets line spacing to that type. For example, if you set the value of the At field to 1.65 em, the value of Line spacing is automatically set to 1.5 lines.
Arbortext Editor's display does not reflect this property.
Single
At
Sets the specific amount of space to be applied between lines when the Specified option is selected in the Line spacing field (see note after table for input options).
Spacing before
Preferred
Specifies the preferred amount of space before the element (prespace). See the note after the table for input options.
8pt
Precedence
Specifies a priority for choosing one element's prespace value over that of another element. Arbortext Editor uses the value from the element with the highest precedence. The choices are
• <Derive> - sets prespace value based on system default, property set, or ancestor settings.
• none
• low
• medium
• high
• force: this option ensures this value is always used, regardless of the precedence settings of other elements.
none
Allow space to vary (Print/PDF only)Minimum
Specifies the minimum amount of prespace that must be applied when spacing of this nature is required (see note after table for input options)
6pt
Allow space to vary (Print/PDF only)Maximum
Specifies the maximum amount of prespace that can be applied when spacing of this nature is used (see note after table for input options).
* 
If the maximum value is greater than the preferred value, the maximum value is treated as a guideline, not as an absolute maximum.
10pt
Keep space at top of column or page (Print/PDF only)
When this option is set to Keep, Arbortext Styler applies the values set in the Spacing before field when the element starts a column or page. When this option is set to Discard (the default), the print composer ignores the values when the element starts a column or page.
Discard
Spacing After
Preferred
Specifies the preferred amount of space after the element (postspace). See the note after the table for input options.
0pt
Precedence
Specifies a priority for choosing one element's postspace value over that of another element. Arbortext Editor uses the value from the element with the highest precedence. Choices are
• <Derive> - sets postspace value based on system default, property set, or ancestor settings.
• none
• low
• medium
• high
• force: this option ensures this value is always used, regardless of the precedence settings of other elements.
space before - medium
space after - high
Allow space to vary (Print/PDF only)Minimum
Specifies the minimum amount of postspace that must be applied when spacing of this nature is required (see note after table for input options)
Derive
Allow space to vary (Print/PDF only)Maximum (Print/PDF only)
Specifies the maximum amount of postspace that can be applied when spacing of this nature is used (see note after table for input options).
* 
If the maximum value is greater than the preferred value, the maximum value is treated as a guideline, not as an absolute maximum.
Derive
Spacing is fixed when the values of Minimum, Maximum, and Preferred are the same. Spacing is variable when the values of Minimum, Maximum, and Preferred are different. Variable spacing can be used to produce better looking pages, and is required for vertical justification, which is specified on the Columns tab of the Page Sets list. Vertical justification enables you to bottom-align columns.
Variable spacing is set up as a default in Arbortext Styler - see property sets such as Standard space in distributed stylesheets. To disable variable spacing, use one of the following methods as applicable:
• Do not reference the property set that is providing the variable spacing setting
• Explicitly set the Minimum and Maximum fields to the same value
• Explicitly set the Minimum and Maximum fields to Derive
* 
The At, Preferred, Minimum, Maximum fields of this tab allow you to either type an arbitrary size in the field or choose a defined size by selecting from the list of Size objects configured for your stylesheet. For the latter option, click the Select Size button The Select Size icon - 3 horizontal lines, a green double ended arrow and a green x, all bounded by vertical lines, with a black down arrow to their right next to the field for which you wish to set the measurement and select the name of the required Size object from the resulting list. Once you have selected a Size object the measurement it defines will be displayed wrapped in angle brackets (< > characters) in the relevant field. For example, the Size object InchSize defines a measurement of 1.00in:
This is an image of the Top field with the InchSize Size listed in the Size definition list activated for the measurement, and the measurement <1.00in> shown in the field
