解決方案提供有：

TIFFEncodeParam tep = new TIFFEncodeParam(); 

// Create {X,Y}Resolution fields. 
TIFFField fieldXRes = new TIFFField(0x11A, TIFFField.TIFF_RATIONAL, 
           1, new long[][] {{DPI_X, 1}}); 
TIFFField fieldYRes = new TIFFField(0x11B, TIFFField.TIFF_RATIONAL, 
           1, new long[][] {{DPI_Y, 1}}); 
tep.setExtraFields(new TIFFField[] {fieldXRes, fieldYRes});
