各类文件头标准编码(16进制) - 判断文件流格式编码
各类文件格式的文件头标志
正好最近在年文件编码及转换方面的资料，弄到文件提取内容的格式判断，可以取文件流中编码的头部编码来进行文件格式的判断。
以下是收集的比较全的文件头标志十六进制编码。
再粘一段格式判断代码(python)，可以根据实际自已判断：
def determine_image_type(stream_first_4_bytes):
"""Find out the image file type based on the magic number comparison of the first 4 (or 2) bytes"""
file_type = None
bytes_as_hex = binascii.b2a_hex(stream_first_4_bytes)
if bytes_as_hex.startswith(b"ffd8", 0, len(bytes_as_hex)):
file_type = '.jpeg'
#89504e47
elif bytes_as_hex.startswith(b"89504e47", 0, len(bytes_as_hex)):
file_type = '.png'
#47494638
elif bytes_as_hex.startswith(b"47494638", 0, len(bytes_as_hex)):
file_type = '.gif'
elif bytes_as_hex.startswith(b"424d", 0, len(bytes_as_hex)):
file_type = '.bmp'
#49492a00
elif bytes_as_hex.startswith(b"49492a", 0, len(bytes_as_hex)):
file_type ='.tif'
return file_type
def save_image(lt_image, page_number, images_folder):
"""Try to save the image data"""
result = None
if lt_image.stream:
file_stream = lt_image.stream.get_rawdata()
if file_stream:
file_ext = determine_image_type(file_stream[0:4])
print("show!!!!",file_stream[0:4])
if file_ext:
file_name = ''.join([str(page_number), '_', lt_image.name, file_ext])
if write_file(images_folder, file_name, file_stream, flags='wb'):
result = file_name
return result

请问一下.kjb和.ktr的文件头怎么提取啊
这个没有找过，原理一样，二进制读取，文件头编码识别。
