extends Object

java.lang.Object
com.sun.javafx.tk.FontMetrics

Imports

javafx.scene.text.Font

The metrics for a Font, including helper functions for computing string width/height and other metrics based on a specific String of text with this font.

Field Summary

Modifier and Type	Field and Description
private float	ascent The distance from the baseline to the avg max character height.
private int	baseline The baseline is the imaginary line upon which letters without descenders (for example, the lowercase letter "a") sits.
private float	descent The distance from the baseline down to the lowest avg.
private Font	font The font that was used to construct these metrics.
private float	leading The amount of space between lines of text in this font.
private float	lineHeight The maximum line height for a line of text in this font
private float	maxAscent The distance from the baseline to the max character height.
private float	maxDescent The distance from the baseline down to the absolute lowest descender.
private float	xheight The distance from the baseline to the top of the avg.

Field Detail

ascent	back to summary
private float ascent The distance from the baseline to the avg max character height. this value is always positive

baseline	back to summary
private int baseline The baseline is the imaginary line upon which letters without descenders (for example, the lowercase letter "a") sits. In terms of the font metrics, all other metrics are derived from this point. This point is implicitly defined as zero.

descent	back to summary
private float descent The distance from the baseline down to the lowest avg. descender. This value is always positive

font	back to summary
private Font font The font that was used to construct these metrics.

leading	back to summary
private float leading The amount of space between lines of text in this font. This is the amount of space between he maxDecent of one line and the maxAscent of the next. This number is included in the lineHeight.

lineHeight	back to summary
private float lineHeight The maximum line height for a line of text in this font

maxAscent	back to summary
private float maxAscent The distance from the baseline to the max character height. This value is always positive

maxDescent	back to summary
private float maxDescent The distance from the baseline down to the absolute lowest descender. this value is always positive

xheight	back to summary
private float xheight The distance from the baseline to the top of the avg. lowercase letter.

getAscent	back to summary
public final float getAscent()

getBaseline	back to summary
public final int getBaseline()

getCharWidth	back to summary
public float getCharWidth(char ch) Computes the width of the char when rendered with the font represented by this FontMetrics instance.

getDescent	back to summary
public final float getDescent()

getFont	back to summary
public final Font getFont()

getLeading	back to summary
public final float getLeading()

getLineHeight	back to summary
public final float getLineHeight()

getMaxAscent	back to summary
public final float getMaxAscent()

getMaxDescent	back to summary
public final float getMaxDescent()

getXheight	back to summary
public final float getXheight()

toString back to summary

public String toString()

Overrides java.lang.Object.toString.

Doc from java.lang.Object.toString.

Returns a string representation of the object. Satisfying this method's contract implies a non-null result must be returned.
