LineMetrics

public LineMetrics()

Method Detail

getNumChars

public abstract int getNumChars()

Returns the number of characters in the Font.

Returns:: the number of characters in the Font.

getAscent

public abstract float getAscent()

Returns the ascent of the Font. The ascent of a Font is the distance from the baseline to the ascender line. The ascent usually represents the the height of the capital letters of the Font.

Returns:: the ascent of the Font.

getDescent

public abstract float getDescent()

Returns the descent of the Font. The descent of a Font is the distance from the baseline to the descender line. The characters of the Font usually do not extend below the descender line.

Returns:: the descent of the Font.

getLeading

public abstract float getLeading()

Returns the leading of the Font. The leading of a Font is the recommended distance from the bottom of the descender line to the top of next line.

Returns:: the leading of the Font.

getHeight

public abstract float getHeight()

Returns the height of the Font. The height is equal to the sum of the ascent, the descent and the leading.

Returns:: the height of the Font.

getBaselineIndex

public abstract int getBaselineIndex()

Returns the current baseline index used for laying out the text of the Font.

Returns:: the baseline index of the Font.

getBaselineOffsets

public abstract float[] getBaselineOffsets()

Returns the baseline offsets as defined in the Font, relative to y=0.

Returns:: the baseline offsets of the Font.

getStrikethroughOffset

public abstract float getStrikethroughOffset()

Returns the position of the strike through line relative to the baseline.

Returns:: the position of the strike through.

getStrikethroughThickness

public abstract float getStrikethroughThickness()

Returns the thickness of the strike through line.

Returns:: the thickness of the strike through line.

getUnderlineOffset

public abstract float getUnderlineOffset()

Returns the position of the underline relative to the descender.

Returns:: the position of the underline.

getUnderlineThickness

public abstract float getUnderlineThickness()

Returns the thickness of the underline.

Returns:: the thickness of the underline.
