setRGB无法解析或不是字段

Question

尝试纠正一组＆＃34;无序像素＆＃34;，在先前使用Array插入的XML文件中列出（x assis上的列数，检测器数量失败）在TIF图像中使用插值（ x-1）和（x +失败的探测器数量）/ 2。 在输入中，我有一个Tif图像，作为单层（PAN，MS1，MS2，MS3，MS4）和数组。在输出中我想要更正新图像。 我在setRGB中遇到了问题：

  

new_img.setRGB =（（row + numOfDetectors）+（row - 1）/ 2）;

和IOException e，在：

  

} catch（IOException e）{

抱歉，我是Java语言的新手。谢谢..
