| void* _imFile::line_buffer |
used for line conversion, contains all components if packed, or only one if not
extra bytes to be allocated
total allocated so far
number of bpp to unpack/pack to/from 1 byte. When reading converts n packed bits to 1 byte (unpack). If n>1 will also expand to 0-255. When writing converts 1 byte to 1 bit (pack). If negative will only expand to 0-255 (no unpack or pack).
flag to switch the original data type: char-byte, short-ushort, uint-int, double-float
