Dear vtk users, How can I read binary image format file ? I use MetaIO file, mhd and raw files. How can I describe mhd header for binary image format file (0-1 values only) ? If 0 and 255 are used for unsigned char type, it is all right, but 0-1 image shows a only black image. Best regards, Oka -- oka <oka at bpe.es.osaka-u.ac.jp>
