public void imageComplete(int status) Implements java.awt.image.ImageConsumer.imageComplete. Doc from java.awt.image.ImageConsumer.imageComplete. 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 occurred. The ImageConsumer should remove itself from the list of consumers registered with the ImageProducer at this time, unless it is interested in successive frames.

setColorModel

back to summary

public void setColorModel(ColorModel model)

Implements java.awt.image.ImageConsumer.setColorModel.

Doc from java.awt.image.ImageConsumer.setColorModel.

Sets the ColorModel object used for the majority of the pixels reported using the setPixels method calls. Note that each set of pixels delivered using setPixels contains its own ColorModel object, so no assumption should be made that this model will be the only one used in delivering pixel values. A notable case where multiple ColorModel objects may be seen is a filtered image when for each set of pixels that it filters, the filter determines whether the pixels can be sent on untouched, using the original ColorModel, or whether the pixels should be modified (filtered) and passed on using a ColorModel more convenient for the filtering process.

setDiffICM	back to summary
private native boolean setDiffICM(int x, int y, int w, int h, int[] lut, int transPix, int numLut, IndexColorModel icm, byte[] pix, int off, int scansize, ByteComponentRaster bct, int chanOff)

setDimensions

back to summary

public void setDimensions(int w, int h)

Implements java.awt.image.ImageConsumer.setDimensions.

Doc from java.awt.image.ImageConsumer.setDimensions.

The dimensions of the source image are reported using the setDimensions method call.

setHints

back to summary

public void setHints(int h)

Implements java.awt.image.ImageConsumer.setHints.

Doc from java.awt.image.ImageConsumer.setHints.

Sets the hints that the ImageConsumer uses to process the pixels delivered by the ImageProducer. The ImageProducer can deliver the pixels in any order, but the ImageConsumer may be able to scale or convert the pixels to the destination ColorModel more efficiently or with higher quality if it knows some information about how the pixels will be delivered up front. The setHints method should be called before any calls to any of the setPixels methods with a bit mask of hints about the manner in which the pixels will be delivered. If the ImageProducer does not follow the guidelines for the indicated hint, the results are undefined.

public void setPixels(int x, int y, int w, int h, ColorModel model, byte[] pix, int off, int scansize)

Implements java.awt.image.ImageConsumer.setPixels.

Doc from java.awt.image.ImageConsumer.setPixels.

Delivers the pixels of the image with one or more calls to this method. Each call specifies the location and size of the rectangle of source pixels that are contained in the array of pixels. The specified ColorModel object should be used to convert the pixels into their corresponding color and alpha components. Pixel (m,n) is stored in the pixels array at index (n * scansize + m + off). The pixels delivered using this method are all stored as bytes.
