jpg图片转tif格式报异常
jpg图片转tif格式报异常，哪位大虾遇到过给帮帮忙啊源码：
PlanarImage image = JAI.create("stream",stream);
TIFFEncodeParam encodeParam = new TIFFEncodeParam();
RenderedOp ro = JAI.create("filestore", image, localPath, "TIFF", encodeParam);
ro.dispose();
异常：
java.lang.RuntimeException: - Unable to render RenderedOp for this operation.
