Constructs an ImageProducer from memory

MemoryImageSource

public MemoryImageSource(int w, int h, int[] pix, int off, int scan, Hashtable<?,?> props)

Constructs an ImageProducer from memory using the default RGB ColorModel.

Parameters: w the image width. h the image height. pix the image data. off the offset to the first pixel in the array. scan the number of array elements from a pixel on one row to the corresponding pixel on the next row. props image properties (null permitted).

MemoryImageSource

public MemoryImageSource(int w, int h, int[] pix, int off, int scan)

Constructs an ImageProducer from memory using the default RGB ColorModel.

Method Detail

addConsumer

public void addConsumer(ImageConsumer ic)

Used to register an ImageConsumer with this ImageProducer.

Parameters: ic the image consumer.

isConsumer

public boolean isConsumer(ImageConsumer ic)

Used to determine if the given ImageConsumer is already registered with this ImageProducer.

Parameters: ic the image consumer.

newPixels

public void newPixels()

Send an animation frame to the image consumers.

newPixels

public void newPixels(int x, int y, int w, int h)

Send an animation frame to the image consumers containing the specified pixels unless setFullBufferUpdates is set.

Parameters: x the x-coordinate. y the y-coordinate. w the width. h the height.

newPixels

public void newPixels(int x, int y, int w, int h, boolean framenotify)

Send an animation frame to the image consumers containing the specified pixels unless setFullBufferUpdates is set. If framenotify is set then a notification is sent when the frame is sent otherwise no status is sent.

Parameters: x the x-coordinate. y the y-coordinate. w the width. h the height. framenotify send notification?

newPixels

public void newPixels(byte[] newpix, ColorModel newmodel, int offset, int scansize)

newPixels

public void newPixels(int[] newpix, ColorModel newmodel, int offset, int scansize)

removeConsumer

public void removeConsumer(ImageConsumer ic)

Used to remove an ImageConsumer from the list of registered consumers for this ImageProducer.

Parameters: ic the image consumer.

requestTopDownLeftRightResend

public void requestTopDownLeftRightResend(ImageConsumer ic)

Used to register an ImageConsumer with this ImageProducer and then request that this producer resend the image data in the order top-down, left-right.

Parameters: ic the image consumer.

setAnimated

public void setAnimated(boolean animated)

Changes a flag to indicate whether this MemoryImageSource supports animations.

Parameters: animated A flag indicating whether this class supports animations

setFullBufferUpdates

public void setFullBufferUpdates(boolean fullbuffers)

A flag to indicate whether or not to send full buffer updates when sending animation. If this flag is set then full buffers are sent in the newPixels methods instead of just regions.

Parameters: fullbuffers a flag indicating whether to send the full buffers

startProduction

public void startProduction(ImageConsumer ic)

Used to register an ImageConsumer with this ImageProducer and then immediately start reconstruction of the image data to be delivered to all registered consumers.
