Examples of WritableRandomIter

javax.media.jai.iterator.WritableRandomIter

An iterator that allows random read/write access to any sample within its bounding rectangle. This flexibility will generally exact a corresponding price in speed and setup overhead.

The iterator is initialized with a particular rectangle as its bounds, which it is illegal to exceed. This initialization takes place in a factory method and is not a part of the iterator interface itself.

The setSample() and setPixel() methods allow individual source samples and whole pixels to be written.

An instance of RandomIter may be obtained by means of the RandomIterFactory.createWritable() method, which returns an opaque object implementing this interface. @see RandomIter @see RandomIterFactory

            height = width;
            width = tmp;
        }
        WritableRaster writableRaster = createDoubleWritableRaster(width, height, null, null, null);


        WritableRandomIter disckRandomIter = RandomIterFactory.createWritable(writableRaster, null);
        for( int x = 0; x < width; x++ ) {
            for( int y = 0; y < height; y++ ) {
                if (matrixIsRowCol) {
                    disckRandomIter.setSample(x, y, 0, matrix[y][x]);
                } else {
                    disckRandomIter.setSample(x, y, 0, matrix[x][y]);
                }
            }
        }
        disckRandomIter.done();


        return writableRaster;
    }
