图像定位及缩放咨询

if (eventResize) {
imgDeck && gr.DrawImage(imgDeck, data_XY_image[1][4], data_XY_image[1][5], data_XY_image[1][6], data_XY_image[1][7], 0, 0, data_XY_image[1][6], data_XY_image[1][7]);//那个
}
请教以上代码：data_XY_image[1][4], data_XY_image[1][5], data_XY_image[1][6], data_XY_image[1][7], 0, 0, data_XY_image[1][6], data_XY_image[1][7]这些中括号里的数字是什么意思？
先谢了！！！
