Method Detail

render

public void render(javax.media.opengl.GL gl,
                   javax.media.opengl.glu.GLU glu)

Description copied from interface: IImageViewport

Renders the picture into the window, according to the viewport settings. If the picture is bigger than the viewport, it is simply centered in it, otherwise, it is scaled in order to fit into the viewport.

Specified by:

render in interface IImageViewport

setImage

public void setImage(Image image,
                     int width,
                     int height)

Set the Image that will be displayed by the layer.

Parameters:

image -

setImage

public void setImage(Image image,
                     int width,
                     int height,
                     ByteBuffer buffer)

setImage

public void setImage(Image image)

getImage

public Image getImage()

Return the image rendered by the AWTImageViewport

getMinimumSize

public Dimension getMinimumSize()

Return the minimum size for this graphic.

Specified by:

getMinimumSize in interface IImageViewport

getPreferedSize

public Dimension getPreferedSize()

Return the prefered size for this graphic.

Specified by:

getPreferedSize in interface IImageViewport

setViewPort

public void setViewPort(int width,
                        int height)

Set the view port (size of the renderer).

Parameters:

width - the width of the target window.

height - the height of the target window.

getMode

public ViewportMode getMode()

setViewportMode

public void setViewportMode(ViewportMode mode)

setViewPort

public void setViewPort(int width,
                        int height,
                        float left,
                        float right)

Set the view port (size of the renderer).

Parameters:

width - the width of the target window.

height - the height of the target window.

left - the width's ratio where this subscreen starts in the target window.

right - the width's ratio where this subscreen stops in the target window.

Throws:

an - IllegalArgumentException if right is not greater than left.

setViewPort

public void setViewPort(ViewportConfiguration viewport)

getLastViewPort

public ViewportConfiguration getLastViewPort()

applyViewport

protected ViewportConfiguration applyViewport(javax.media.opengl.GL gl,
                                              javax.media.opengl.glu.GLU glu)

Build and return a ViewportConfiguration. Uses gl to

• apply viewport
• optionnaly to render the viewport debug grid

Parameters:

gl -

glu -

getRectangle

public Rectangle getRectangle()

Returns the (x,y) offset that was applied to make this AbstractViewportManager stand in the appropriate canvas part. and the actual width and height of the viewport. Only relevant after a call to applyViewPort.

setScreenGridDisplayed

public void setScreenGridDisplayed(boolean status)

Set the status of the screen grid.

Parameters:

status - the grid is displayed if status is set to true
