Class SVGTextElem

java.lang.Object
  com.tinyline.svg.SVGNode
      com.tinyline.svg.SVGTextElem

public class SVGTextElem
extends SVGNode

The SVGTextElem class implements the 'text' element.

The 'text' element defines a graphics element consisting of text. The character data within the 'text' element, along with relevant attributes and properties and character-to-glyph mapping tables within the font itself, define the glyphs to be rendered.

Version:

2.2

Field Summary

TinyString	str The character data within the 'text' element
int	x The x-axis coordinate of the current text position for rendering the glyphs that correspond to the first character within this element or any of its descendants.
int	y The y-axis coordinate of the current text position for rendering the glyphs that correspond to the first character within this element or any of its descendants.

Constructor Detail

SVGTextElem

public SVGTextElem(SVGTextElem src)

Constructs a copy of the given SVGTextElem node. (It DOES NOT copy the outline!).

Method Detail

copyNode

public SVGNode copyNode()

Constructs a copy of the given node.

Specified by:

copyNode in class SVGNode

createOutline

public int createOutline()

Creates the outline for this node.

Specified by:

createOutline in class SVGNode

getAttribute

public java.lang.Object getAttribute(int hattr)

Returns the value object for the given attribute, or null object otherwise.

Overrides:

getAttribute in class SVGNode

Parameters:

hattr - The attribute handle.

Returns:

The value of the attribute or null.

getBounds

public TinyRect getBounds()

Returns the user bounding box for this SVGNode. COORDINATES ARE IN USER SPACE. If this SVGNode doesnt have its own geometry, the getBounds() returns null.

Overrides:

getBounds in class SVGNode

getDevBounds

public TinyRect getDevBounds(SVGRaster renderer)

Returns the device bounding box for this SVGNode. COORDINATES ARE IN DEVICE SPACE. If this SVGNode doesnt have its own geometry, the getDevBounds() returns null.

Overrides:

getDevBounds in class SVGNode

Parameters:

renderer - The SVGRaster object.

getText

public TinyString getText()

Returns the text of this SVGNode as a char array.

nodeHitAt

public SVGNode nodeHitAt(SVGRaster renderer,
                         TinyPoint p)

Returns the SVGNode node containing TinyPoint p.

Overrides:

nodeHitAt in class SVGNode

Parameters:

renderer - The SVGRaster object

p - the specified TinyPoint in DEVICE SPACE 12/26/2008 6:41AM

paint

public void paint(SVGRaster renderer)

Draws this node.

Specified by:

paint in class SVGNode

Parameters:

renderer - Handle to the SVGRaster object that does the drawing.

setAttribute

public int setAttribute(int hattr,
                        java.lang.Object value)
                 throws java.lang.Exception

Assigns or modifies the value of the specified attribute.

Overrides:

setAttribute in class SVGNode

Parameters:

hattr - The attribute handle.

value - The value of the attribute.

Returns:

The error code that could be one of the following: SVG.ERR_OK, SVG.ERR_NUMBER_FORMAT, SVG.ERR_INVALID_ARG, SVG.ERR_NOT_FOUND, SVG.ERR_NOT_SUPPORTED, SVG.ERR_HIERARCHY_REQUEST

Throws:

java.lang.Exception - if the value type doesn not match to the attribute handle.

setText

public int setText(char[] value,
                   int offset,
                   int count)

Sets the new text of this SVGNode as a char array.

Parameters:

value - array that is the source of characters.

offset - the initial offset.

count - the length.
