使用Python进行错误更正而不进行分块

Question

我在尝试使用Reed Solomon对（字节）字符串进行纠错，然后再将其发送到接收器。我使用以下library进行纠错，并使用以下MWE：

from reedsolo import RSCodec

with open("imageToSend.png", "rb") as pic:
  picContent = pic.read()

correctionLength = int((len(picContent)/100)*20)
rs = RSCodec(correctionLength)

rs.encode(picContent)

由于这对我的用例不起作用（删除整个255字节块不可恢复），我正在寻找一种新方法。我想做以下事情：

with open("imageToSend.png", "rb") as pic:
  picContent = pic.read()

# Create error correcting code of picContent and append it to the message (without chunking the message)

# Randomly delete 20% of the message

# Correct errors and restore original message

性能（速度）不是问题！
