Auto leading starts with a base amount of leading, which the application calculates by
examining the ascent and descent values built into the fonts used in an auto-leaded line
and the line above it; however, the user-specified text size plays the largest part in
determining this base amount. Finally, a value specified by the user in the Auto Leading
field is added to the base amount to arrive at the total amount of leading.
To specify percentage-based auto leading, enter a value from 0% to 100% in 1% increments.
This value determines the amount of leading between two lines of text as follows: The
largest font size in the line above is multiplied by the percentage value. This outcome is
added to the base amount of auto leading between the two lines. Although the design of
certain fonts complicates the process, here is a simplified example: 10-point text styled
consistently in a "standard" font with Auto Leading set to 20% has 12 points of leading
(10 pts + [20% of 10] = 12 pts).
Use the Maintain Leading check box to control the placement of a line of text that falls
immediately below an obstruction in a column or box. If Maintain Leading is checked,
the line's baseline is placed according to its applied leading value. If Maintain Leading is
unchecked, the ascent of the line will abut the bottom of the obstruction or any applied
runaround value.
In the Lock to Grid Based On area:
Click Ascent and Descent to lock text to grid based on the ascenders and descenders of
characters.
Click Font Size (Em Box) to lock text to grid based on the size of the em boxes of the
characters.
Preferences Character
The Character pane (Administration > Preferences > Renderer > Character) includes
the following controls.
Use the Superscript fields to control the placement and scale (size) of superscript characters.
The Superscript Offset value determines how far below the baseline the application places
a superscript character. The Superscript Offset value is measured as a percentage of font
size. The default value is 33%. The Superscript VScale value determines the vertical size
of the character and is a percentage of font size. The Superscript HScale value determines
width and is a percentage of the normal character width (as specified by the font designer).
The default value for both scales is 60% (range = 0 to 100%, measurement system =
percentage, smallest increment = .1).
Use the Subscript fields to control the placement and scale (size) of subscript characters.
The Subscript Offset value determines how far above the baseline the application places
a subscript character. The Subscript Offset value is measured as a percentage of font size.
The default value is 33%. The Subscript VScale value determines the vertical size of the
character and is a percentage of font size. The Subscript HScale value determines width
and is a percentage of the normal character width (as specified by the font designer). The
default value for both scales is 100% (range = 0 to 100%, measurement system = percentage,
smallest increment = .1).
