TextLeafSvgNodeRenderer

public TextLeafSvgNodeRenderer()

Method Detail

createDeepCopy

public ISvgNodeRenderer createDeepCopy()

Description copied from interface: ISvgNodeRenderer

Creates a deep copy of this renderer, including it's subtree of children

Specified by:

createDeepCopy in interface ISvgNodeRenderer

Returns:

deep copy of this renderer

getTextContentLength

@Deprecated
public float getTextContentLength(float parentFontSize,
                                  PdfFont font)

Deprecated.

Description copied from interface: ISvgTextNodeRenderer

Gets text content length.

Specified by:

getTextContentLength in interface ISvgTextNodeRenderer

Parameters:

parentFontSize - parent font size

font - current font

Returns:

text content length

getRelativeTranslation

@Deprecated
public float[] getRelativeTranslation()

Deprecated.

Description copied from interface: ISvgTextNodeRenderer

This method is deprecated and will be replaced with new signature getRelativeTranslation(SvgDrawContext). This is needed because xMove/yMove can contain relative values, so SvgDrawContext is needed to resolve them.

Specified by:

getRelativeTranslation in interface ISvgTextNodeRenderer

Returns:

text relative translation

containsRelativeMove

@Deprecated
public boolean containsRelativeMove()

Deprecated.

Description copied from interface: ISvgTextNodeRenderer

This method is deprecated and will be replaced with new signature containsRelativeMove(SvgDrawContext). This is needed because xMove/yMove can contain relative values, so SvgDrawContext is needed to resolve them.

Specified by:

containsRelativeMove in interface ISvgTextNodeRenderer

Returns:

true if there is a relative move, false otherwise

containsAbsolutePositionChange

@Deprecated
public boolean containsAbsolutePositionChange()

Deprecated.

Description copied from interface: ISvgTextNodeRenderer

This method is deprecated and will be replaced with new signature containsAbsolutePositionChange(SvgDrawContext). This is needed because x/y can contain relative values, so SvgDrawContext is needed to resolve them.

Specified by:

containsAbsolutePositionChange in interface ISvgTextNodeRenderer

Returns:

true if an absolute position is specified via x/y attributes, false otherwise

getAbsolutePositionChanges

@Deprecated
public float[][] getAbsolutePositionChanges()

Deprecated.

Description copied from interface: ISvgTextNodeRenderer

This method is deprecated and will be replaced with new signature getAbsolutePositionChanges(SvgDrawContext). This is needed because x/y can contain relative values, so SvgDrawContext is needed to resolve them.

Specified by:

getAbsolutePositionChanges in interface ISvgTextNodeRenderer

Returns:

text absolute position

getTextRectangle

public TextRectangle getTextRectangle(SvgDrawContext context,
                                      Point startPoint)

Description copied from interface: ISvgTextNodeRenderer

Return the bounding rectangle of the text element.

Specified by:

getTextRectangle in interface ISvgTextNodeRenderer

Parameters:

context - current SvgDrawContext

startPoint - end point of previous text element

Returns:

created instance of TextRectangle

getObjectBoundingBox

public Rectangle getObjectBoundingBox(SvgDrawContext context)

Description copied from interface: ISvgNodeRenderer

Calculates the current object bounding box.

Specified by:

getObjectBoundingBox in interface ISvgNodeRenderer

Parameters:

context - the current context, for instance it contains current viewport and available font data

Returns:

the Rectangle representing the current object's bounding box, or null if bounding box is undefined

doDraw

protected void doDraw(SvgDrawContext context)

Description copied from class: AbstractSvgNodeRenderer

Draws this element to a canvas-like object maintained in the context.

Specified by:

doDraw in class AbstractSvgNodeRenderer

Parameters:

context - the object that knows the place to draw this element and maintains its state

canElementFill

protected boolean canElementFill()

Description copied from class: AbstractSvgNodeRenderer

Method to see if a certain renderer can use fill.

Overrides:

canElementFill in class AbstractSvgNodeRenderer

Returns:

true if the renderer can use fill

applyTransform

private void applyTransform(SvgDrawContext context)

applyGraphicsState

private void applyGraphicsState(SvgDrawContext context)

layoutText

private LineRenderer layoutText(SvgDrawContext context)
