21.6 java.awt.image.ImageConsumer (JDK 1.0)

This interface defines the methods necessary for a class that consumes image data to communicate with a class that produces image data. The methods defined by this interface should never be called by a program directly; instead, they are invoked by an ImageProducer to pass the image data and other information about the image to the ImageConsumer. The constants defined by this interface are values passed to the setHints() and imageComplete() methods.

Unless you want to do low-level manipulation of image data, you never need to use or implement an ImageConsumer.

public abstract interface ImageConsumer {
    // Constants
            public static final int COMPLETESCANLINES;
            public static final int IMAGEABORTED;
            public static final int IMAGEERROR;
            public static final int RANDOMPIXELORDER;
            public static final int SINGLEFRAME;
            public static final int SINGLEFRAMEDONE;
            public static final int SINGLEPASS;
            public static final int STATICIMAGEDONE;
            public static final int TOPDOWNLEFTRIGHT;
    // Public Instance Methods
            public abstract void imageComplete(int status);
            public abstract void setColorModel(ColorModel model);
            public abstract void setDimensions(int width, int height);
            public abstract void setHints(int hintflags);
            public abstract void setPixels(int x, int y, int w, int h, ColorModel model, byte[] pixels, int off, int scansize);
            public abstract void setPixels(int x, int y, int w, int h, ColorModel model, int[] pixels, int off, int scansize);
            public abstract void setProperties(Hashtable props);
