You can use the ColorControlAdapter class. You'll find it at package com.sun.media.controls
JMF is poorly documented.. I've found many informations in http://jsourcery.com/output/sun/jmf/2.1.1e/com/sun/media/controls/package-summary.html
ColorControlAdapter.java:
package com.sun.media.controls;
import java.awt.Component;
import javax.media.Control;
// Referenced classes of package com.sun.media.controls:
// AtomicControlAdapter, ColorControl, NumericControl, BooleanControl
public class ColorControlAdapter extends AtomicControlAdapter
implements ColorControl
public ColorControlAdapter(NumericControl b, NumericControl c, NumericControl s, NumericControl h, BooleanControl g, Component comp, boolean def,
Control parent)
super(comp, def, parent);
brightness = b;
contrast = c;
saturation = s;
hue = h;
grayscale = g;
int n = 0;
n += b != null ? 1 : 0;
n += c != null ? 1 : 0;
n += s != null ? 1 : 0;
n += h != null ? 1 : 0;
n += g != null ? 1 : 0;
controls = new Control[n];
n = 0;
if(b != null)
controls[n++] = b;
if(c != null)
controls[n++] = c;
if(s != null)
controls[n++] = s;
if(h != null)
controls[n++] = h;
if(g != null)
controls[n++] = g;
public Control[] getControls()
return controls;
public NumericControl getBrightness()
return brightness;
public NumericControl getContrast()
return contrast;
public NumericControl getSaturation()
return saturation;
public NumericControl getHue()
return hue;
public BooleanControl getGrayscale()
return grayscale;
NumericControl brightness;
NumericControl contrast;
NumericControl saturation;
NumericControl hue;
BooleanControl grayscale;
Control controls[];
I hope that I help someone.. I spend many time until found it..
