ImageGraphicAttribute
public ImageGraphicAttribute(Image image, int alignment)
Constucts anImageGraphicAttribute
from the specifiedImage
. The origin is at (0, 0).- Parameters:
image
- theImage
rendered by thisImageGraphicAttribute
. This object keeps a reference toimage
.alignment
- one of the alignments from thisImageGraphicAttribute
-
ImageGraphicAttribute
public ImageGraphicAttribute(Image image, int alignment, float originX, float originY)
Constructs anImageGraphicAttribute
from the specifiedImage
. The point (originX
,originY
) in theImage
appears at the origin of theImageGraphicAttribute
within the text.- Parameters:
image
- theImage
rendered by thisImageGraphicAttribute
. This object keeps a reference toimage
.alignment
- one of the alignments from thisImageGraphicAttribute
originX
- the X coordinate of the point within theImage

getAscent
public float getAscent()
Returns the ascent of thisImageGraphicAttribute
. The ascent of anImageGraphicAttribute
is the distance from the top of the image to the origin.- Specified by:
getAscent
in classGraphicAttribute
- Returns:
- the ascent of this
ImageGraphicAttribute
. - See Also:
GraphicAttribute.getBounds()
-
getDescent
public float getDescent()
Returns the descent of thisImageGraphicAttribute
. The descent of anImageGraphicAttribute
is the distance from the origin to the bottom of the image.- Specified by:
getDescent
in classGraphicAttribute
- Returns:
- the descent of this
ImageGraphicAttribute
. - See Also:
GraphicAttribute.getBounds()
-
getAdvance
public float getAdvance()
Returns the advance of thisImageGraphicAttribute
. The advance of anImageGraphicAttribute
is the distance from the origin to the right edge of the image.- Specified by:
getAdvance
in classGraphicAttribute
- Returns:
- the advance of this
ImageGraphicAttribute
. - See Also:
GraphicAttribute.getBounds()
-
getBounds
public Rectangle2D getBounds()
Returns aRectangle2D
that encloses all of the bits rendered by thisImageGraphicAttribute
, 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 classGraphicAttribute
- Returns:
- a
Rectangle2D
that encloses all of the bits rendered by thisImageGraphicAttribute
.
-
draw
public void draw(Graphics2D graphics, float x, float y)
Renders thisGraphicAttribute
at the specified location.- Specified by:
draw
in classGraphicAttribute
- Parameters:
graphics
- theGraphics2D
into which to render the graphicx
- the user-space X coordinate where the graphic is renderedy
- the user-space Y coordinate where the graphic is rendered
-
hashCode
public int hashCode()
Returns a hashcode for thisImageGraphicAttribute
.- Overrides:
hashCode
in classObject
- Returns:
- a hash code value for this object.
- See Also:
Object.equals(java.lang.Object)
,System.identityHashCode(java.lang.Object)
-

public boolean equals(Object rhs)
Compares thisImageGraphicAttribute
to the specifiedObject
.- Overrides:
equals
in classObject
- Parameters:
rhs
- theObject
to compare for equality- Returns:
true
if thisImageGraphicAttribute
equalsrhs
;false
otherwise.- See Also:
Object.hashCode()
,HashMap
-
equals
public boolean equals(ImageGraphicAttribute rhs)
Compares thisImageGraphicAttribute
to the specifiedImageGraphicAttribute
.- Parameters:
rhs
- theImageGraphicAttribute
to compare for equality- Returns:
true
if thisImageGraphicAttribute
equalsrhs
;false
otherwise.
