I am looking for the most efficient method of replacing a repeating sequence in a byte string returned from a imaging .dll, connected viaI receive the byte string with the following sequence 'bgrbgrbgrbgr' and I would like to convert this to 'rbgrbgrbgrbg'
For speed, I would look at PIL or pygame for existing function, or use numpy -- read into 2-d array, swap first and third members, flatten.
