Package gov.nih.mipav.model.algorithms

Class ContourPlot.CompleteRenderer

java.lang.Object

gov.nih.mipav.model.algorithms.ContourPlot.CompleteRenderer

All Implemented Interfaces:

ContourPlot.AdaptableView, ContourPlot.PDFRenderer, ContourPlot.Renderer

Enclosing class:

ContourPlot

public class ContourPlot.CompleteRenderer
extends Object
implements ContourPlot.Renderer, ContourPlot.AdaptableView

The ContourPlot.CompleteRenderer comprises a ContourPlot.LinesRenderer, a

invalid reference

PointsRenderer

, a ContourPlot.TextRenderer and a ContourPlot.TrianglesRenderer. It thus can render the most important graphical elements for a scientific 2D visualization (hence its name).

The order in which these Renderers are processed by default is:

1. ContourPlot.Triangles
2. ContourPlot.Lines
3. invalid reference

   Curves

4. ContourPlot.Points
5. ContourPlot.Text

This implies that Lines will be drawn over Triangles, Curves over Lines, Points over Curves, and Text over Points. Using the

invalid reference

#setRenderOrder(int, int, int, int, int)

method the order of renderers can be changed.

To add ContourPlot.Renderables to this Renderer either use the public attributes triangles, lines,

invalid reference

#curves

,

invalid reference

#points

, text to directly access the desired renderer or use the addItemToRender(Renderable) method.

Constructor Details

CompleteRenderer

public CompleteRenderer()

Method Details

isEnabled

public boolean isEnabled()

Description copied from interface: ContourPlot.Renderer

Whether this renderer is enabled or not. By default a renderer is enabled and will render upon

invalid reference

#render(int, int, int, int)

or

invalid reference

#renderSVG(org.w3c.dom.Document, org.w3c.dom.Element, int, int)

. When disabled those methods return right away and will not render anything.

Specified by:

isEnabled in interface ContourPlot.Renderer

Returns:

true when active

renderFallback

public void renderFallback(Graphics2D g,
 Graphics2D p,
 int w,
 int h)

Description copied from interface: ContourPlot.Renderer

Renders this ContourPlot.Renderer's 'scene'. This is the fallback path in case OpenGL based rendering through

invalid reference

#render(int, int, int, int)

is not available.

Specified by:

renderFallback in interface ContourPlot.Renderer

Parameters:

g - main graphics object for drawing onto the framebuffer

p - graphics object for drawing onto the picking framebuffer (invisible but used for picking)

w - width of the current viewport in pixels

h - height of the current viewport in pixels

renderPDF

public void renderPDF(org.apache.pdfbox.pdmodel.PDDocument doc,
 org.apache.pdfbox.pdmodel.PDPage page,
 int x,
 int y,
 int w,
 int h)

Description copied from interface: ContourPlot.PDFRenderer

Renders this PDFRenderers contents, that is creating pdf elements and appending them to the specified page within the corresponding document.

Specified by:

renderPDF in interface ContourPlot.PDFRenderer

Parameters:

doc - the PDF document holding the page

page - page in pdf doc to which elements are to be appended

x - x coordinate of the current viewport

y - y coordinate of the current viewport

w - width of the current viewport

h - height of the current viewport

addItemToRender

public ContourPlot.CompleteRenderer addItemToRender(ContourPlot.Renderable item)

Adds the specified item to the corresponding renderer. Only instances of ContourPlot.Triangles, ContourPlot.Lines, ContourPlot.Points and ContourPlot.Text are accepted, other item types result in an IllegalArgumentException.

Parameters:

item - to add

Returns:

this for chaining

Throws:

IllegalArgumentException - when unsupported type of item is specified.

setView

public void setView(Rectangle2D rect)

Sets the view matrix for each of the renderers

Specified by:

setView in interface ContourPlot.AdaptableView

Parameters:

rect - the view rectangle (can be null)
