The pixmap

public Object getProperty(String name,
                          ImageObserver observer)

This method requests a named property for an object. The value of the property is returned. The value UndefinedProperty is returned if there is no property with the specified name. The value null is returned if the properties for the object are not yet known. In this case, the specified image observer is notified when the properties are known.

Overrides:

getProperty in interface Image

Parameters:

name - the requested property name

observer - the image observer for this object

Returns:

the named property, if available

See Also:

Image.UndefinedProperty

public ImageProducer getSource()

Returns the image producer object for this object. The producer is the object which generates pixels for this image.

Overrides:

getSource in interface Image

Returns:

the image producer for this object

public int getWidth()

Returns the width of the image, or -1 if it is unknown. If the image width is unknown, the observer object will be notified when the value is known.

Returns:

the width in pixels

See Also:

getHeight()

public int getWidth(ImageObserver observer)

Returns the width of the image, or -1 if it is unknown. If the image width is unknown, the observer object will be notified when the value is known.

Overrides:

getWidth in interface Image

Parameters:

observer - the image observer for this object

Returns:

the width in pixels

See Also:

getHeight(ImageObserver)

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.

Specified by:

imageComplete in interface ImageConsumer

Parameters:

status - the status of image production, represented by a bitwise OR of ImageConsumer flags

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.

Specified by:

setColorModel in interface ImageConsumer

Parameters:

model - the color model to be used most often by setPixels

See Also:

ColorModel

public void setDimensions(int width,
                          int height)

An ImageProducer indicates the size of the image being produced using this method.

Specified by:

setDimensions in interface ImageConsumer

Parameters:

width - the width of the image

height - the height of the image

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.

Specified by:

setHints in interface ImageConsumer

Parameters:

flags - a bit mask of hints

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.

Specified by:

setPixels in interface ImageConsumer

Parameters:

x - x coordinate of pixel block

y - y coordinate of pixel block

w - width of pixel block

h - height of pixel block

model - color model used to interpret pixel data

pixels - pixel block data

offset - offset into pixels array

scansize - width of one row in the pixel block

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.

Specified by:

setPixels in interface ImageConsumer

Parameters:

x - x coordinate of pixel block

y - y coordinate of pixel block

w - width of pixel block

h - height of pixel block

model - color model used to interpret pixel data

pixels - pixel block data

offset - offset into pixels array

scansize - width of one row in the pixel block
