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.

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.
