extracting bits from bytes [message #1535] Mon, 29 November 1993 15:29

I have a (graphic) file that is an 8-bit byte. Each of the 8 bits in each
byte indicates the graphic position is on or off.

Is there a way with IDL to determine which of the 8 bits is on (1) or
off (0)? Like it can be done in FORTRAN or C.
