Language Version: | ActionScript 3.0 |
Runtime Versions: | Flash Player 10, AIR 1.5 |
Defines values for setting the
leadingModel
property
of the
TextLayoutFormat
class, composed of valid combinations of leading basis and leading direction.
Leading basis describes which baselines determine the leading (or
lineHeight
) of lines in a paragraph.
Leading direction specifies whether the
lineHeight
property refers to the distance of a line's
baseline from that of the line before it or the line after it.
public static const APPROXIMATE_TEXT_FIELD:String = "approximateTextField"
Language Version: | ActionScript 3.0 |
Runtime Versions: | Flash Player 10, AIR 1.5 |
Specifies a leading model that approximates the line spacing behavior of TextField
.
It is similar to ASCENT_DESCENT_UP
in that lineHeight
refers to the
distance of a line's ascent baseline from the previous line's descent baseline. However, baseline
positions approximate those determined by TextField
, rather than using metrics
offered by TextLine
.
public static const ASCENT_DESCENT_UP:String = "ascentDescentUp"
Language Version: | ActionScript 3.0 |
Runtime Versions: | Flash Player 10, AIR 1.5 |
Specifies that leading basis is ASCENT/DESCENT and leading direction is UP.
In other words, lineHeight
refers to the distance of a line's ascent baseline from the
previous line's descent baseline.
public static const AUTO:String = "auto"
Language Version: | ActionScript #IDEOGRAPHIC_TOP_DOWN |
Runtime Versions: | Flash Player 10, AIR 1.5 |
Specifies that leading model is chosen automatically based on the paragraph's locale
property.
For Japanese and Chinese, it is IDEOGRAPHIC_TOP_DOWN and for all others it is ROMAN_UP.
public static const IDEOGRAPHIC_CENTER_DOWN:String = "ideographicCenterDown"
Language Version: | ActionScript 3.0 |
Runtime Versions: | Flash Player 10, AIR 1.5 |
Specifies that leading basis is IDEOGRAPHIC_CENTER and leading direction is down.
In other words, lineHeight
refers to the distance of a line's ideographic center
baseline from the next line's ideographic center baseline.
public static const IDEOGRAPHIC_CENTER_UP:String = "ideographicCenterUp"
Language Version: | ActionScript 3.0 |
Runtime Versions: | Flash Player 10, AIR 1.5 |
Specifies that leading basis is IDEOGRAPHIC_CENTER and leading direction is UP.
In other words, lineHeight
refers to the distance of a line's ideographic center
baseline from the previous line's ideographic center baseline.
public static const IDEOGRAPHIC_TOP_DOWN:String = "ideographicTopDown"
Language Version: | ActionScript 3.0 |
Runtime Versions: | Flash Player 10, AIR 1.5 |
Specifies that leading basis is IDEOGRAPHIC_TOP and leading direction is DOWN.
In other words, lineHeight
refers to the distance of a line's ideographic top baseline
from the next line's ideographic top baseline.
public static const IDEOGRAPHIC_TOP_UP:String = "ideographicTopUp"
Language Version: | ActionScript 3.0 |
Runtime Versions: | Flash Player 10, AIR 1.5 |
Specifies that leading basis is IDEOGRAPHIC_TOP and leading direction is UP.
In other words, lineHeight
refers to the distance of a line's ideographic top
baseline from the previous line's ideographic top baseline.
public static const ROMAN_UP:String = "romanUp"
Language Version: | ActionScript 3.0 |
Runtime Versions: | Flash Player 10, AIR 1.5 |
Specifies that leading basis is ROMAN and leading direction is UP.
In other words, lineHeight
refers to the distance of a line's Roman baseline from the
previous line's Roman baseline.
