示例1: run

import java.awt.image.ColorModel; //導入方法依賴的package包/類
/**
 * The runnable method for this class. This will produce an image using
 * the current RenderableImage and RenderContext and send it to all the
 * ImageConsumer currently registered with this class.
 */

    RenderedImage rdrdImage;
    if (rc != null) {
        rdrdImage = rdblImage.createRendering(rc);

    // And its ColorModel
    ColorModel colorModel = rdrdImage.getColorModel();

    // Get RGB pixels from the raster scanline by scanline and
    // send to consumers.

            ic.setPixels(0, j, width, 1, colorModel, pix, 0, width);
