Program records can be read with the following regular expression (here in python with the re module):

import re
 
data_pattern = re.compile('''
(PG)            # type of data
.{4}            # 4 characters
([^\xff]{1,8})  # data name
\xff{16,23}     # between 16 and 23 (16+8-len(data name)) 0xFF
(NL|BN)              # Option1 (NL=normal, BN=base)
\xff{13}        # 13 0xFF
.{8}            # 8 characters
([^\xff]+\xff)  # any non 0xFF characters ended by one 0xFF : raw data
''', re.VERBOSE)
 
fxd_file = open(fxd_filename, 'rb')
out_ctn = data_pattern.findall(fxd_file.read())
fxd_file.close()
 
# out_ctn is the list of records
# each record is like:
# ("DATA TYPE", "FILE NAME", "OPTION", "RAW DATA")
# DATA TYPE is always "PG" (programs)
# FILE NAME is the name of the program
# OPTION is "NL" for normal program, "BN" for program with base operation
# RAW DATA is the content of the program, in the raw format
 
# You can get those data with this code:
 
for record in out_ctn:
    data_type, file_name, option, raw_data = record
    # you can now use data_type, file_name, option and raw_data

Picture records can be read with the following regular expression (here in python with the re module):

import re
 
pictures_pattern = re.compile('''

# each record is like:
# ("PICTURE NAME", "SHEET1", "SHEET2", "SHEET3", "SHEET4")
# PICTURE NAME is the name of the picture
# SHEET1, SHEET2, SHEET3 and SHEET4 are the four sheet of the picture
 
# You can get those data with this code:

    file_name, sheet1, sheet2, sheet3, sheet4 = record
    # You can now build the picture using sheet1 to sheet4
    # The picture is more or less in the casio picture format:

    # but without the colour byte. Just add a colour byte \x01 to \x04
    # at the beginning of each sheet, join the result, and you'll get a
    # picture in the casio picture format, with the colour byte at 0,
    # and the pallet: [orange, blue, green, white]
    # Example:
    casio_picture = '\x01' + sheet1 + \

                    '\x03' + sheet3 + \

Mono screen capture records can be read with the following regular expression (here in python with the re module):

# out_ctn is the list of records
# each record is like:
