                            boolean useMaxLineHeight,
                            boolean imageResolutionMapping)

Method Detail

createTextSizeCalculator

public SizeCalculator createTextSizeCalculator(FontDefinition font)
                                        throws SizeCalculatorException

Creates a size calculator for the current state of the output target. The calculator is used to calculate the string width and line height and later maybe more...

Specified by:

createTextSizeCalculator in interface LayoutSupport

Parameters:

font - the font.

Returns:

the size calculator.

Throws:

SizeCalculatorException - if there is a problem with the output target.

getVerticalAlignmentBorder

public float getVerticalAlignmentBorder()

Returns the element alignment. Elements will be layouted aligned to this border, so that mod(X, horizontalAlignment) == 0 and mod(Y, verticalAlignment) == 0. Returning 0 will disable the alignment.

Specified by:

getVerticalAlignmentBorder in interface LayoutSupport

Returns:

the vertical alignment grid boundry

getHorizontalAlignmentBorder

public float getHorizontalAlignmentBorder()

Returns the element alignment. Elements will be layouted aligned to this border, so that mod(X, horizontalAlignment) == 0 and mod(Y, verticalAlignment) == 0. Returning 0 will disable the alignment.

Specified by:

getHorizontalAlignmentBorder in interface LayoutSupport

Returns:

the vertical alignment grid boundry

getInternalHorizontalAlignmentBorder

public long getInternalHorizontalAlignmentBorder()

Returns the element alignment. Elements will be layouted aligned to this border, so that mod(X, horizontalAlignment) == 0 and mod(Y, verticalAlignment) == 0. Returning 0 will disable the alignment.

Q&D Hack: Save some cycles of processor time by computing that thing only once.

Specified by:

getInternalHorizontalAlignmentBorder in interface LayoutSupport

Returns:

the vertical alignment grid boundry

getInternalVerticalAlignmentBorder

public long getInternalVerticalAlignmentBorder()

Returns the element alignment. Elements will be layouted aligned to this border, so that mod(X, horizontalAlignment) == 0 and mod(Y, verticalAlignment) == 0. Returning 0 will disable the alignment.

Specified by:

getInternalVerticalAlignmentBorder in interface LayoutSupport

Returns:

the vertical alignment grid boundry

getContentFactory

public ContentFactory getContentFactory()

RetFixurns the assigned content factory for the target.

Specified by:

getContentFactory in interface LayoutSupport

Returns:

the content factory.

getCache

public LayoutManagerCache getCache()

Specified by:

getCache in interface LayoutSupport

isImageResolutionMappingActive

public boolean isImageResolutionMappingActive()
