Coded Images

Ask Steve to tell you about the tiny hairs he had to remove from his Cheerios as a kid. Darn bowl cuts.

- I tend to jest, rather than read anything.

I tried it out, loading an image, encoding a string and then doing _SAVEIMAGE on it. Then reloading the saved version and decoding. It worked fine on a PNG, but I get a null string when trying it on a JPG. Haven't tried any others.

I like it as a crypto exercise.

JPEG images lack the alpha channel. BMP should work. TGAs alpha channel implementation is a bit weird, I think. So, not sure about that one.

You need to save using a non-lossy format.

I'd have to dig up my code from the 90s. I sent Mac an image once, and he said it wouldn't load. I then sent him my qb utility I threw together, and asked him to run it and input the name of the image. It was a clown laughing an pointing at the user. Mac replied something to the effect. I have bad news to share with you about your program. It worked as advertised.

What's old is new again, but now in 128-bits.
