Interface ImageConsumer
- AreaAveragingScaleFilter, BufferedImageFilter, CropImageFilter, GrayFilter, ImageFilter, PixelGrabber, ReplicateScaleFilter, RGBImageFilter
An object implementing the ImageProducer
interface can
use objects implementing this interface to deliver the image data.
static int | COMPLETESCANLINES - The pixel order is in multiples of complete scanlines.
|
static int | IMAGEABORTED - Production of the image has been aborted.
|
static int | IMAGEERROR - Indicates an error occurred while producing an image.
|
static int | RANDOMPIXELORDER - The pixel order may be random.
|
static int | SINGLEFRAME - The pixels will be delivered with multiple calls to
setPixels .
|
static int | SINGLEFRAMEDONE - A single frame is complete but more will follow.
|
static int | SINGLEPASS - The pixels will be delivered in a single pass.
|
static int | STATICIMAGEDONE - The image is complete and no more pixels or frames will follow.
|
static int | TOPDOWNLEFTRIGHT - The pixel order is top-down, left-right.
|
void | imageComplete(int status) - The
ImageProducer calls this method to indicate a
single frame or the entire image is complete.
|
void | setColorModel(ColorModel model) - This
ColorModel should indicate the model used by
the majority of calls to setPixels .
|
void | setDimensions(int width, int height) - An
ImageProducer indicates the size of the image
being produced using this method.
|
void | setHints(int flags) - The
ImageProducer should call this method with a
bit mask of hints from any of RANDOMPIXELORDER ,
TOPDOWNLEFTRIGHT , COMPLETESCANLINES ,
SINGLEPASS , SINGLEFRAME .
|
void | setPixels(int x, int y, int w, int h, ColorModel model, byte[] pixels, int offset, int scansize) - Deliver a subset of an ImageProducer's pixels to this ImageConsumer.
|
void | setPixels(int x, int y, int w, int h, ColorModel model, int[] pixels, int offset, int scansize) - Deliver a subset of an ImageProducer's pixels to this ImageConsumer.
|
void | setProperties(Hashtable , ?> props) - An
ImageProducer can set a list of properties
associated with this image by using this method.
|
COMPLETESCANLINES
public static final int COMPLETESCANLINES
The pixel order is in multiples of complete scanlines.
IMAGEABORTED
public static final int IMAGEABORTED
Production of the image has been aborted.
IMAGEERROR
public static final int IMAGEERROR
Indicates an error occurred while producing an image.
RANDOMPIXELORDER
public static final int RANDOMPIXELORDER
The pixel order may be random. This should be
the default assumption of the ImageConsumer
.
SINGLEFRAME
public static final int SINGLEFRAME
The pixels will be delivered with multiple calls to
setPixels
. The image contains a single frame
which ends when imageComplete
is called with the
STATICIMAGEDONE
flag. If the image is constantly
changing such as with video then the end of each frame is
marked by a similar call to imageComplete
with the
SINGLEFRAMEDONE
flag.
SINGLEFRAMEDONE
public static final int SINGLEFRAMEDONE
A single frame is complete but more will follow.
SINGLEPASS
public static final int SINGLEPASS
The pixels will be delivered in a single pass. There is at
most one call to setPixels
for any single pixel.
STATICIMAGEDONE
public static final int STATICIMAGEDONE
The image is complete and no more pixels or frames will follow.
TOPDOWNLEFTRIGHT
public static final int TOPDOWNLEFTRIGHT
The pixel order is top-down, left-right.
imageComplete
public void imageComplete(int status)
The ImageProducer
calls this method to indicate a
single frame or the entire image is complete. The method is
also used to indicate an error in loading or producing the
image.
status
- the status of image production, represented by a
bitwise OR of ImageConsumer flags
setColorModel
public void setColorModel(ColorModel model)
This ColorModel
should indicate the model used by
the majority of calls to setPixels
. Each call to
setPixels
could however indicate a different
ColorModel
.
model
- the color model to be used most often by setPixels
setDimensions
public void setDimensions(int width,
int height)
An ImageProducer
indicates the size of the image
being produced using this method.
width
- the width of the imageheight
- the height of the image
setHints
public void setHints(int flags)
The ImageProducer
should call this method with a
bit mask of hints from any of RANDOMPIXELORDER
,
TOPDOWNLEFTRIGHT
, COMPLETESCANLINES
,
SINGLEPASS
, SINGLEFRAME
.
flags
- a bit mask of hints
setPixels
public void setPixels(int x,
int y,
int w,
int h,
ColorModel model,
byte[] pixels,
int offset,
int scansize)
Deliver a subset of an ImageProducer's pixels to this ImageConsumer.
Each element of the pixels array represents one pixel. The
pixel data is formatted according to the color model model.
The x and y parameters are the coordinates of the block of
pixels being delivered to this ImageConsumer. They are
specified relative to the top left corner of the image being
produced. Likewise, w and h are the pixel block's dimensions.
x
- x coordinate of pixel blocky
- y coordinate of pixel blockw
- width of pixel blockh
- height of pixel blockmodel
- color model used to interpret pixel datapixels
- pixel block dataoffset
- offset into pixels arrayscansize
- width of one row in the pixel block
setPixels
public void setPixels(int x,
int y,
int w,
int h,
ColorModel model,
int[] pixels,
int offset,
int scansize)
Deliver a subset of an ImageProducer's pixels to this ImageConsumer.
Each element of the pixels array represents one pixel. The
pixel data is formatted according to the color model model.
The x and y parameters are the coordinates of the rectangular
region of pixels being delivered to this ImageConsumer,
specified relative to the top left corner of the image being
produced. Likewise, w and h are the pixel region's dimensions.
x
- x coordinate of pixel blocky
- y coordinate of pixel blockw
- width of pixel blockh
- height of pixel blockmodel
- color model used to interpret pixel datapixels
- pixel block dataoffset
- offset into pixels arrayscansize
- width of one row in the pixel block
setProperties
public void setProperties(Hashtable ,
?> props)
An ImageProducer
can set a list of properties
associated with this image by using this method.
props
- the list of properties associated with this image
