Convert base64 into a image (PNG/JPEG) file

How can I leverage your package to convert a base64 variable into a png/jpeg file in R

Strict decoding

Hi Simon,

I have been using your R package, base64enc (version 0.1-3), and like it. Thank you very much for writing and sharing it!

However, I came across a problem, where invalid base64 strings (e.g. “u” or “aGVsbG8sd29ybGQh=”) are successfully and silently processed by base64decode(). In my code, I therefore had to use this regular expression (adapted from http://stackoverflow.com/a/8571649) to validate the strings before decoding them:

^(([A-Za-z0-9+/]{4})*([A-Za-z0-9+/]{4}|[A-Za-z0-9+/]{3}=|[A-Za-z0-9+/]{2}==))?$`

May I suggest that you add an option "strict" to base64decode() (defaulting to FALSE for backward compatibility) to detect and report malformed base64 strings?

Best,

Florent

`null` character

Trying to do this via R rather than perl, R chokes on the "\000.........\000......." part. (perl does fine)

License info

I'm confused by the license info at "GPL-2 | GPL-3."

Edit: I think this means "or"

Document how to submit bugs

Hi,

The latest CPAN release (and current development code I believe) simply mention Simon's email address and the rforge website (which does not seem to have a bug tracker). Github is mentioned nowhere. Therefore, most users do not know that there is a bugtracker (Github) and will just send an email, which I believe is not the intent or the best way to proceed.

So, perhaps update the DESCRIPTION file with the Github URL?

Best,

Florent
