public interface ImageObserver
| Modifier and Type | Field and Description | 
|---|---|
| static int | ABORTThis flag in the infoflags argument to imageUpdate indicates that
 an image which was being tracked asynchronously was aborted before
 production was complete. | 
| static int | ALLBITSThis 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. | 
| static int | ERRORThis flag in the infoflags argument to imageUpdate indicates that
 an image which was being tracked asynchronously has encountered
 an error. | 
| static int | FRAMEBITSThis flag in the infoflags argument to imageUpdate indicates that
 another complete frame of a multi-frame image which was previously
 drawn is now available to be drawn again. | 
| static int | HEIGHTThis flag in the infoflags argument to imageUpdate indicates that
 the height of the base image is now available and can be taken
 from the height argument to the imageUpdate callback method. | 
| static int | PROPERTIESThis flag in the infoflags argument to imageUpdate indicates that
 the properties of the image are now available. | 
| static int | SOMEBITSThis flag in the infoflags argument to imageUpdate indicates that
 more pixels needed for drawing a scaled variation of the image
 are available. | 
| static int | WIDTHThis flag in the infoflags argument to imageUpdate indicates that
 the width of the base image is now available and can be taken
 from the width argument to the imageUpdate callback method. |

boolean imageUpdate(Image img, int infoflags, int x, int y, int width, int height)
This method should return true if further updates are needed or false if the required information has been acquired. The image which was being tracked is passed in using the img argument. Various constants are combined to form the infoflags argument which indicates what information about the image is now available. The interpretation of the x, y, width, and height arguments depends on the contents of the infoflags argument.
 The infoflags argument should be the bitwise inclusive
 OR of the following flags: WIDTH,
 HEIGHT, PROPERTIES, SOMEBITS,
 FRAMEBITS, ALLBITS, ERROR,
 ABORT.
