Constructor Detail

ImageGraphicAttribute

public ImageGraphicAttribute(Image image,
                             int alignment)

Constucts an ImageGraphicAttribute from the specified Image. The origin is at (0, 0).

Parameters:

image - the Image rendered by this ImageGraphicAttribute. This object keeps a reference to image.

alignment - one of the alignments from this ImageGraphicAttribute

ImageGraphicAttribute

public ImageGraphicAttribute(Image image,
                             int alignment,
                             float originX,
                             float originY)

Constructs an ImageGraphicAttribute from the specified Image. The point (originX, originY) in the Image appears at the origin of the ImageGraphicAttribute within the text.

Parameters:

image - the Image rendered by this ImageGraphicAttribute. This object keeps a reference to image.

alignment - one of the alignments from this ImageGraphicAttribute

Method Detail

getAscent

public float getAscent()

Returns the ascent of this ImageGraphicAttribute. The ascent of an ImageGraphicAttribute is the distance from the top of the image to the origin.

Specified by:

getAscent in class GraphicAttribute

Returns:

the ascent of this ImageGraphicAttribute.

See Also:

GraphicAttribute.getBounds()

getDescent

public float getDescent()

Returns the descent of this ImageGraphicAttribute. The descent of an ImageGraphicAttribute is the distance from the origin to the bottom of the image.

Specified by:

getDescent in class GraphicAttribute

Returns:

the descent of this ImageGraphicAttribute.

See Also:

GraphicAttribute.getBounds()

getAdvance

public float getAdvance()

Returns the advance of this ImageGraphicAttribute. The advance of an ImageGraphicAttribute is the distance from the origin to the right edge of the image.

Specified by:

getAdvance in class GraphicAttribute

Returns:

the advance of this ImageGraphicAttribute.

See Also:

GraphicAttribute.getBounds()

getBounds

public Rectangle2D getBounds()

Returns a Rectangle2D that encloses all of the bits rendered by this ImageGraphicAttribute, relative to the rendering position. A graphic can be rendered beyond its origin, ascent, descent, or advance; but if it is, this method's implementation must indicate where the graphic is rendered.

Overrides:

getBounds in class GraphicAttribute

Returns:

a Rectangle2D that encloses all of the bits rendered by this ImageGraphicAttribute.

draw

public void draw(Graphics2D graphics,
                 float x,
                 float y)

Renders the graphic at the specified location.

Specified by:

draw in class GraphicAttribute

Parameters:

graphics - the Graphics2D into which to render the graphic

hashCode

public int hashCode()

Returns a hashcode for this ImageGraphicAttribute.

Overrides:

hashCode in class Object

Returns:

a hash code value for this object.

See Also:

Object.equals(java.lang.Object), Hashtable

equals

public boolean equals(Object rhs)

Compares this ImageGraphicAttribute to the specified Object.

Overrides:

equals in class Object

Parameters:

rhs - the Object to compare for equality

Returns:

true if this ImageGraphicAttribute equals rhs; false otherwise.

See Also:

Object.hashCode(), Hashtable

equals

public boolean equals(ImageGraphicAttribute rhs)

Compares this ImageGraphicAttribute to the specified ImageGraphicAttribute.

Parameters:

rhs - the ImageGraphicAttribute to compare for equality

Returns:

true if this ImageGraphicAttribute equals rhs; false otherwise.
