# 2D-FRUTTI Definitions
# The 2D-FRUTTI standard readable by the 2D-FRUTTI reader:
#
# 1. 8 bits / byte
# 2. ASCII character code
# 3. 16 bit, twos complement with least significant bytes first
#
# The following deviations from the 2D-FRUTTI standard are allowed:
#
# A user specified flag allows selecting most significant byte format
define CAM_BYTE 8 # Number of bits in 2D-FRUTTI byte
define BITPIX 16 # Bits per 2D-FRUTTI data values
#define LSBF YES # Least Significant Byte First
