Interface ZoomRaster

All Known Implementing Classes:
ZoomRasterImpl

public interface ZoomRaster
extends Raster, RasterS

A zoomable Raster.. ZoomRaster is a subclass of Raster that implements a zoomable image. It handles translation between logical coordinates and screen coordinates.

          Special method for ZoomRasters.
 int getZoomFactor()
          Get the current zoom factor.
 void handleConfigureWidth$Height(int newWidth, int newHeight)
          Reconfigures the ZoomRaster when the window is resized.
 void increaseZoom()
          Make the raster bigger.

Method Detail

increaseZoom

public void increaseZoom()
Make the raster bigger.

decreaseZoom

public void decreaseZoom()
Make the raster smaller.

getZoomFactor

public int getZoomFactor()
Get the current zoom factor.

fillCenteredRectangleX0$Y0$X1$Y1$Color

public void fillCenteredRectangleX0$Y0$X1$Y1$Color(int x0,
                                                   int y0,
                                                   int x1,
                                                   int y1,
                                                   byte color)
Special method for ZoomRasters. Like fillRectangleX0:Y0:X1:Y1:Color: in Raster, it will fill a rectangle of given geometry and color. This method makes sure that zooming the window does not change the logical position of the rectangle in relation to the logical coordinates. In other words, if a rectangle includes point (10,10) at one zoom factors, then that same point is included for all zoom factors.

setZoomFactor

public java.lang.Object setZoomFactor(int z)
Set the zoom factor.

handleConfigureWidth$Height

public void handleConfigureWidth$Height(int newWidth,
                                        int newHeight)
Reconfigures the ZoomRaster when the window is resized.
