This flag in the infoflags argument to imageUpdate indicates that a static image which was previously drawn is now complete and can be drawn again in its final form.

Usage

From source file:org.pentaho.reporting.libraries.base.util.WaitingImageObserver.java

/**
 * Callback function used by AWT to inform that more data is available. The observer waits until either all data is
 * loaded or AWT signals that the image cannot be loaded.
 *
 * @param img       the image being observed.
 * @param infoflags the bitwise inclusive OR of the following flags:  <code>WIDTH</code>, <code>HEIGHT</code>,
 *                  <code>PROPERTIES</code>, <code>SOMEBITS</code>, <code>FRAMEBITS</code>, <code>ALLBITS</code>,
 *                  <code>ERROR</code>, <code>ABORT</code>.
 * @param x         the <i>x</i> coordinate.
 * @param y         the <i>y</i> coordinate.
 * @param width     the width./*  www . j  ava 2 s  .c  om*/
 * @param height    the height.
 * @return <code>false</code> if the infoflags indicate that the image is completely loaded; <code>true</code>
 * otherwise.
