FontShearSpan
public final class FontShearSpan extends MetricAffectingSpan
| java.lang.Object | |||
| ↳ | android.text.style.CharacterStyle | ||
| ↳ | android.text.style.MetricAffectingSpan | ||
| ↳ | androidx.text.vertical.FontShearSpan | ||
A span that applies a shear (skew) transformation to the vertical writing text.
This span inherits from MetricAffectingSpan, but it is specifically designed for use within a VerticalTextLayout and will not have an effect in other contexts.
It is used to achieve an italic-like effect for vertical text layout, where traditional italic fonts may not render correctly.
The shear value represents the horizontal skew factor for rotated or tate-chu-yoko text. For upright text, this value is used as the vertical skew factor.
See DEFAULT_FONT_SHEAR for the default value.
Note: This span only works with VerticalTextLayout.
