          Get the metadata associated with the image being read.

int getWidth(int imageIndex)
          Get the width of the input image in pixels.

void imageComplete(int status)
          The ImageProducer calls this method to indicate a single frame or the entire image is complete.

java.awt.image.BufferedImage read(int imageIndex, javax.imageio.ImageReadParam param)
          Read the given frame into a buffered image using the given read parameters.

void setColorModel(java.awt.image.ColorModel model)
          This ColorModel should indicate the model used by the majority of calls to setPixels.

void setDimensions(int w, int h)
          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 setInput(java.lang.Object input, boolean seekForwardOnly, boolean ignoreMetadata)
          Set the input source to the given object, specify whether this reader should be allowed to read input from the data stream more than once, and specify whether this reader should ignore metadata in the input stream.

void setPixels(int x, int y, int w, int h, java.awt.image.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, java.awt.image.ColorModel model, int[] pixels, int offset, int scansize)
          Deliver a subset of an ImageProducer's pixels to this ImageConsumer.

void setProperties(java.util.Hashtable props)
          An ImageProducer can set a list of properties associated with this image by using this method.

Method Detail

setDimensions

public void setDimensions(int w,
                          int h)

Description copied from interface: java.awt.image.ImageConsumer

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

Specified by:: setDimensions in interface java.awt.image.ImageConsumer

setProperties

public void setProperties(java.util.Hashtable props)

Description copied from interface: java.awt.image.ImageConsumer

An ImageProducer can set a list of properties associated with this image by using this method.

Specified by:: setProperties in interface java.awt.image.ImageConsumer

setColorModel

public void setColorModel(java.awt.image.ColorModel model)

Description copied from interface: java.awt.image.ImageConsumer

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 java.awt.image.ImageConsumer

setHints

public void setHints(int flags)

Description copied from interface: java.awt.image.ImageConsumer

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 java.awt.image.ImageConsumer

setPixels

public void setPixels(int x,
                      int y,
                      int w,

Description copied from interface: java.awt.image.ImageConsumer

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.

                      int scansize)

Description copied from interface: java.awt.image.ImageConsumer

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.
