| public RenderedImage | createDefaultRendering()
Returns a RenderedImage instance of this image with a default
width and height in pixels. | | public RenderedImage | createRendering(RenderContext renderContext)
Creates a RenderedImage that represented a rendering of this image

height h in pixels. | | public float | getHeight()
Gets the height in user coordinate space. | | protected synchronized ImageServer | getImageServer(String serverName)

host:port
where the port number is optional and may be supplied only if
the host name is supplied. | | public float | getMinX()

Gets the minimum Y coordinate of the rendering-independent image data. | | public String | getOperationName()
Returns the operation name. | | public Object | getProperty(String name)
Gets a property from the property set of this image.
If the property name is not recognized, java.awt.Image.UndefinedProperty
will be returned.
Parameters:
name - the name of the property to get, as a String. | | public String[] | getPropertyNames()
Returns a list of names recognized by getProperty. | | public Long | getRMIID()
Returns the ID that refers to the RenderableOp on the
server. | | public String | getServerName()
Returns the name of the server on which the RenderableOp exists. | | public Vector | getSources()
Returns a vector of RenderableImages that are the sources of
image data for this RenderableImage. | | public float | getWidth()
Gets the width in user coordinate space. | | public boolean | isDynamic()
Returns true if successive renderings (that is, calls to
createRendering() or createScaledRendering()) with the same arguments
may produce different results. |
| id | | public Long id(Code) | | The ID that refers to the RenderableOp on the server.
|
| RenderableRMIServerProxy | | public RenderableRMIServerProxy(String serverName, String operationName, ParameterBlock paramBlock, Long opID)(Code) | | Creates a RenderableRMIServerProxy to access the
RenderableOp on the server identified by the
supplied opID.
|
| createDefaultRendering | | public RenderedImage createDefaultRendering() throws RemoteImagingException(Code) | | Returns a RenderedImage instance of this image with a default
width and height in pixels. The RenderContext is built
automatically with an appropriate usr2dev transform and an area
of interest of the full image. The rendering hints are
empty. createDefaultRendering may make use of a stored
rendering for speed.
a RenderedImage containing the rendered data. |
| createRendering | | public RenderedImage createRendering(RenderContext renderContext) throws RemoteImagingException(Code) | | Creates a RenderedImage that represented a rendering of this image
using a given RenderContext. This is the most general way to obtain a
rendering of a RenderableImage.
The created RenderedImage may have a property identified
by the String HINTS_OBSERVED to indicate which RenderingHints
(from the RenderContext) were used to create the image.
In addition any RenderedImages
that are obtained via the getSources() method on the created
RenderedImage may have such a property.
Parameters:
renderContext - the RenderContext to use to produce the rendering. a RenderedImage containing the rendered data. |
| createScaledRendering | | public RenderedImage createScaledRendering(int w, int h, RenderingHints hints) throws RemoteImagingException(Code) | | Creates a RenderedImage instance of this image with width w, and
height h in pixels. The RenderContext is built automatically
with an appropriate usr2dev transform and an area of interest
of the full image. All the rendering hints come from hints
passed in.
If w == 0, it will be taken to equal
Math.round(h*(getWidth()/getHeight())).
Similarly, if h == 0, it will be taken to equal
Math.round(w*(getHeight()/getWidth())). One of
w or h must be non-zero or else an IllegalArgumentException
will be thrown.
The created RenderedImage may have a property identified
by the String HINTS_OBSERVED to indicate which RenderingHints
were used to create the image. In addition any RenderedImages
that are obtained via the getSources() method on the created
RenderedImage may have such a property.
Parameters:
w - the width of rendered image in pixels, or 0.
Parameters:
h - the height of rendered image in pixels, or 0.
Parameters:
hints - a RenderingHints object containg hints. a RenderedImage containing the rendered data. |
| getHeight | | public float getHeight() throws RemoteImagingException(Code) | | Gets the height in user coordinate space. By convention, the
usual height of a RenderedImage is equal to 1.0F.
the height of the image in user coordinates. |
| getImageServer | | protected synchronized ImageServer getImageServer(String serverName)(Code) | | Construct an ImageServer on the indicated server.
The name of the server must be supplied in the form
host:port
where the port number is optional and may be supplied only if
the host name is supplied. If this parameter is null the default
is to search for the ImageServer service on the local host at the
default rmiregistry port (1099).
The result is cached in the instance variable "remoteImage".
Parameters:
serverName - The name of the server in the format described. |
| getMinX | | public float getMinX() throws RemoteImagingException(Code) | | Gets the minimum X coordinate of the rendering-independent image data.
the minimum X coordinate of the rendering-independent imagedata. |
| getMinY | | public float getMinY() throws RemoteImagingException(Code) | | Gets the minimum Y coordinate of the rendering-independent image data.
the minimum Y coordinate of the rendering-independent imagedata. |
| getOperationName | | public String getOperationName()(Code) | | Returns the operation name.
|
| getProperty | | public Object getProperty(String name) throws RemoteImagingException(Code) | | Gets a property from the property set of this image.
If the property name is not recognized, java.awt.Image.UndefinedProperty
will be returned.
Parameters:
name - the name of the property to get, as a String. a reference to the property Object, or the valuejava.awt.Image.UndefinedProperty. |
| getRMIID | | public Long getRMIID()(Code) | | Returns the ID that refers to the RenderableOp on the
server.
|
| getServerName | | public String getServerName()(Code) | | Returns the name of the server on which the RenderableOp exists.
|
| getSources | | public Vector getSources()(Code) | | Returns a vector of RenderableImages that are the sources of
image data for this RenderableImage. Note that this method may
return an empty vector, to indicate that the image has no sources,
or null, to indicate that no information is available.
a (possibly empty) Vector of RenderableImages, or null. |
| getWidth | | public float getWidth() throws RemoteImagingException(Code) | | Gets the width in user coordinate space. By convention, the
usual width of a RenderableImage is equal to the image's aspect
ratio (width divided by height).
the width of the image in user coordinates. |
| isDynamic | | public boolean isDynamic() throws RemoteImagingException(Code) | | Returns true if successive renderings (that is, calls to
createRendering() or createScaledRendering()) with the same arguments
may produce different results. This method may be used to
determine whether an existing rendering may be cached and
reused. It is always safe to return true.
true if successive renderings with thesame arguments might produce different results;false otherwise. |
