class ShadowCanvas extends Canvas implements Runnable {

// 原始图片
Image srcImage;
// 原始图片的像素数组
int[] srcRgbImage;
// 渐变图片的像素数组

int count;

srcImage = Image.createImage("/av.png");
} catch (IOException e) {

imgWidth = srcImage.getWidth();
imgHeight = srcImage.getHeight();
// 制造原始图片的像素数组，用一个int来代表每一个像素,按位表示方式是:0xAARRGGBB
