public interface ImageConsumer
The interface for objects expressing interest in image data through the ImageProducer interfaces. When a consumer is added to an image producer, the producer delivers all of the data about the image using the method calls defined in this interface.
ImageProducer
Field Summary | |
---|---|
static int |
COMPLETESCANLINES
The pixels will be delivered in (multiples of) complete scanlines at a time. |
static int |
IMAGEABORTED
The image creation process was deliberately aborted. |
static int |
IMAGEERROR
An error was encountered while producing the image. |
static int |
RANDOMPIXELORDER
The pixels will be delivered in a random order. |
static int |
SINGLEFRAME
The image contain a single static image. |
static int |
SINGLEFRAMEDONE
One frame of the image is complete but there are more frames to be delivered. |
static int |
SINGLEPASS
The pixels will be delivered in a single pass. |
static int |
STATICIMAGEDONE
The image is complete and there are no more pixels or frames to be delivered. |
static int |
TOPDOWNLEFTRIGHT
The pixels will be delivered in top-down, left-to-right order. |
Method Summary | |
---|---|
void |
imageComplete(int status)
The imageComplete method is called when the ImageProducer is finished delivering all of the pixels that the source image contains, or when a single frame of a multi-frame animation has been completed, or when an error in loading or producing the image has occured. |
void |
setColorModel(ColorModel model)
Sets the ColorModel object used for the majority of the pixels reported using the setPixels method calls. |
void |
setDimensions(int width,
int height)
The dimensions of the source image are reported using the setDimensions method call. |
void |
setHints(int hintflags)
Sets the hints that the ImageConsumer uses to process the pixels delivered by the ImageProducer. |
void |
setPixels(int x,
int y,
int w,
int h,
ColorModel model,
byte[] pixels,
int off,
int scansize)
Delivers the pixels of the image with one or more calls to this method. |
void |
setPixels(int x,
int y,
int w,
int h,
ColorModel model,
int[] pixels,
int off,
int scansize)
The pixels of the image are delivered using one or more calls to the setPixels method. |
void |
setProperties(Hashtable<?,?> props)
Sets the extensible list of properties associated with this image. |
