Python Seismic1:判断segy文件的编码格式是IBM还是IEEE

判断segy文件的编码格式是IBM还是IEEE

# code for judge a segy file IEEE or IBM 
format = 'nothing'
fileName = "vp_marmousi-ii.segy"
fSegy = open(fileName,"rb")
fSegy.seek(3225,0) 
tempValue = fSegy.read(1)
hexValue = tempValue.hex()
decValue = int(hexValue,16)
if decValue == 1:
    format = 'IBM'
else:
    if decValue == 5:
        format = 'IEEE'
print(format)


# 1=4字节IBM浮点数
# 2=4字节，两互补整数
# 3=2字节，两互补整数
# 5=4字节IEEE浮点数
