how to convert png image into base64 string and vice versa?
You probably need to supply more information to get the answer you want. But to answer your question as asked:
using Base64
data = read("image.png")
text=base64encode(data)
println(text)
To go back to a file you would do:
output = base64decode(text)
write("image.2.png", output)
BTW: Googling for “julia base64” bring me to:
https://docs.julialang.org/en/v1/stdlib/Base64/
Which is what I did to answer the question
