Handling binary data

[spaceelephant]

Import variable only supports text, and importing binary data will result in it trying to decode the data into UTF-8, which doesn't work. My file library works in this case, returning the binary file, but it requires javascript. Is there a way to import binary files using snap variables?

Good question. I don't think so, but we should have that capability.

If you can convert your data into Base64, then it can be imported and decoded within Snap!

Decode and Encode a Base64 string

I've finally got round to making a Base64 decoder using the information from Base64 Decode Algorithm | Base64 Algorithm | Learn | Base64 [image] It's very naive and takes 22 seconds to decode a 100x100 encoded image on my computer! So, if anyone fancies improving it (no JS of course) I'd be really grateful The final image should look like this (it's a tile of part of an earthnullschool.net wind map) but the decoder must decode the simple ones as well in order to be compliant …
