我检查了com.sun.media.imageioimpl.plugins.jpeg2000.J2KRenderedImageCodecLib类，发现未设置xStep和yStep变量的值：
for (int i = 0; i < size.csize; i++) {
decoder.decodeCompParams(compParam, i);
if(i == 0) {
xStep = compParam.xstep;
yStep = compParam.ystep;
} else if(compParam.xstep != xStep || compParam.ystep != yStep) {
// All components must have same subsampling along each axis.
throw new IIOException
("All components must have the same subsampling factors!");
}
}
因为此循环未运行。我该怎么做才能运行它？
