![]() Why 64? Because you can generally rely on the same 64 characters being present in many character sets, and you can be reasonably confident that your data's going to end up on the other side of the wire uncorrupted. ![]() Base64 is one of these types of encodings. So to get around this, people encode the binary data into characters. You never know - some protocols may interpret your binary data as control characters (like a modem), or your binary data could be screwed up because the underlying protocol might think that you've entered a special character combination (like how FTP translates line endings). Why? because some media are made for streaming text. When you have some binary data that you want to ship across a network, you generally don't do it by just streaming the bits and bytes over the wire in a raw format. This is to ensure that the data remain intact without modification during transport. Here, I am getting confused i don't understand that converting image to jpg file is called encoding or converting image to data is called encodingīase64 encoding schemes are commonly used when there is a need to encode binary data that needs to be stored and transferred over media that are designed to deal with ASCII. ![]() I see that image is converted into data as shown in this link. How are you transferring the images between the pc/pi that takes the picture and the server that stores it? But in this case, there is not need to encode before sending it to a server and then decoding it there. The only other encoding I can think of as far as image to is that camera take a RAW image from the sensor and encode it into JPG, or PNG or whatever other format and that is what gets saved. I can think of encoding text data being sent between one pc and another as they must agree in what's being transfered and how to read it, but for binary data (which an image is), you just need to send the bytes that make up the image (or compress the image first, so less bytes need to be sent) ![]() There is no need to encode images before sending and decoding after receiving.ĭo you mean compression, where the pic might be 500mb uncompressed, 500KB after compressing it and then sending it to the server where it decompresses it before it can be used by something else there? Print(Base64Encoder.encode(file_data.You might be using the wrong terms.
