Method Detail

render

public void render(IPainter painter)

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

Parameters:

painter - TODO

renderImage

protected void renderImage(IPainter painter,
                           ByteBuffer imageBuffer,
                           int imageWidth,
                           int imageHeight,
                           int screenWidth,
                           int screenHeight,
                           float z)

updatePixelScale

protected void updatePixelScale(Coord2d pixelScale)

Update internal pixel scale knowledge. Called by render loop and provided by painter's view. May be overrided to update the image.

setImage

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

Set the Image that will be displayed by the layer.

                     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:
