[Bug awt/24023] New: java.awt.Image.getScaledInstance not implemented

[WBaer at gmx dot de]

Hi all,

java.awt.Image.getScaledInstance is not completely implemented. 

The following two scale flag cases are not implemented:
case SCALE_SMOOTH:
case SCALE_AREA_AVERAGING:
default:
  throw new Error("not implemented");

This is done quickly however the needed classes 
java/awt/image/ReplicateScaleFilter and
java/awt/image/AreaAveragingScaleFilter are only
stub classes.

This causes the startup error for JUMP. A simple 
workaround is to use the other scale flag types
until the classes are properly implemented:

switch (flags)
  {
    case SCALE_DEFAULT:
    case SCALE_FAST:
    case SCALE_REPLICATE:
    case SCALE_SMOOTH: 
       // FIXME Implement java/awt/image/ReplicateScaleFilter
    case SCALE_AREA_AVERAGING: 
      // FIXME Implement java/awt/image/AreaAveragingScaleFilter
      ImageProducer producer =
        new FilteredImageSource(this.getSource(),
            new ReplicateScaleFilter(width, height));
      return Toolkit.getDefaultToolkit().createImage(producer);     
    }
