Field Detail

TEXTFLIP

protected static final com.itextpdf.kernel.geom.AffineTransform TEXTFLIP

Top level transformation to flip the y-axis results in the character glyphs being mirrored, this tf corrects for this behaviour

performRootTransformations

@Deprecated
protected boolean performRootTransformations

Deprecated.

Constructor Detail

TextSvgBranchRenderer

public TextSvgBranchRenderer()

Creates new TextSvgBranchRenderer instance.

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

addChild

public final void addChild(ISvgTextNodeRenderer child)

Adds a child to the current TextSvgBranchRenderer renderer.

Parameters:

child - ISvgTextNodeRenderer child to add

getChildren

public final List<ISvgTextNodeRenderer> getChildren()

Retrieves a list of all children of the current TextSvgBranchRenderer renderer.

Returns:

a list of ISvgTextNodeRenderer children

getTextContentLength

@Deprecated
public float getTextContentLength(float parentFontSize,
                                              com.itextpdf.kernel.font.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

getRelativeTranslation

public float[] getRelativeTranslation(SvgDrawContext context)

Gets relative translation of the current <text> or <tspan> element.

Parameters:

context - current SvgDrawContext

Returns:

float array that contains relative dx and dy translations

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

containsRelativeMove

public boolean containsRelativeMove(SvgDrawContext context)

Checks whether current <text> or <tspan> element contains relative position change.

Parameters:

context - current SvgDrawContext

Returns:

true is current element contains relative position, false otherwise

containsAbsolutePositionChange

public boolean containsAbsolutePositionChange()

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

containsAbsolutePositionChange

public boolean containsAbsolutePositionChange(SvgDrawContext context)

Checks whether current <text> or <tspan> element contains absolute position attributes.

Parameters:

context - current SvgDrawContext

Returns:

true is current element contains absolute position, false otherwise

getAbsolutePositionChanges

public float[][] getAbsolutePositionChanges()

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

getAbsolutePositionChanges

public float[][] getAbsolutePositionChanges(SvgDrawContext context)

Gets absolute position of the current <text> or <tspan> element.

Parameters:

context - current SvgDrawContext

Returns:

float array that contains absolute x and y positions as either single item arrays or null if attribute is not present

markWhiteSpaceProcessed

public void markWhiteSpaceProcessed()

Marks white-space property as processed.

getTextRectangle

public TextRectangle getTextRectangle(SvgDrawContext context,
                                      com.itextpdf.kernel.geom.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 com.itextpdf.kernel.geom.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)

Method that will set properties to be inherited by this branch renderer's children and will iterate over all children in order to draw them.

Specified by:

doDraw in class AbstractSvgNodeRenderer

Parameters:

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