GC绘图，图像拷贝方法原型:@param image the source image@param srcX the x coordinate in the source image to copy from@param srcY the y coordinate in the source image to copy from@param srcWidth the width in pixels to copy from the source@param srcHeight the height in pixels to copy from the source@param destX the x coordinate in the destination to copy to@param destY the y coordinate in the destination to copy to@param destWidth the width in pixels of the destination rectangle@param destHeight the height in pixels of the destination rectanglepublic void drawImage(Image image, int srcX, int srcY, int srcWidth, int srcHeight, int destX, int destY, int destWidth, int destHeight) {
eg:gc.drawImage(image,0,0, rect.width, rect.height,0,0, rect.width / 2, rect.height / 2);
gc.drawImage(image, 6, 44, 162, 193, 2,2,162,193);表示从image的(6,44)位置开始拷贝162*193大小的图片区域，放到目标位置的(2,2)处162*193大小的矩形区域内若目标区域比源图片拷贝大小要小，则压缩图片，否则拉伸图片
