                                                                                 double fontSize,
                                                                                 boolean bold,

Computes the font-metrics using the given properties.

This method is a implementation detail. Use it in an output target, but be aware that it may change between releases.

Parameters:

fontFamily - the font family.

fontSize - the font size.

bold - a flag indicating whether the font should be displayed in bold.

italics - a flag indicating whether the font should be displayed in italics.

encoding - a valid font encoding, can be null to use the default.

embedded - a flag indicating whether the font is intended for embedded use.

antiAliasing - a flag indicating whether the font should be rendered in aliased mode.

Returns:

the font metrics, never null.

Throws:

IllegalArgumentException - if the font family was invalid and no default family could be located.

getBaselineInfo

public ExtendedBaselineInfo getBaselineInfo(int codePoint,
                                            StyleSheet styleSheet)

Specified by:

getBaselineInfo in interface OutputProcessorMetaData

getFontMetrics

public org.pentaho.reporting.libraries.fonts.registry.FontMetrics getFontMetrics(StyleSheet styleSheet)
                                                                          throws IllegalArgumentException

Returns the font metrics for the font specified in the style sheet.

NOTE: This method will throw an IllegalArgumentException if the specified font family can not be found and the default font family can not be found

Specified by:

getFontMetrics in interface OutputProcessorMetaData

Parameters:

styleSheet - ths style sheet from which the font information will be extracted

Returns:

FontMetrics for the specified font. If the font family can not be found, the FontMetrics for the default font family will be returned

Throws:

IllegalArgumentException - indicated the font metrics could not be determined (this is thrown since methods depending upon this method can not handle a null return).

commit

public void commit()

Specified by:

commit in interface OutputProcessorMetaData

isExtraContentElement

public boolean isExtraContentElement(StyleSheet style,
                                     ReportAttributeMap attributes)

Checks whether this element provides some extra content that is not part of the visible layout structure. This can be embedded scripts, anchors etc.

Specified by:

isExtraContentElement in interface OutputProcessorMetaData

Parameters:

style -

attributes -

Returns:
