decode

TL;DR : I need a way to decode a QR-code from an image file using (preferable pure) Python. I've got a jpg file with a QR-code which I want to decode using Python. I've found a couple libraries which claim to do this: PyQRCode ( website here ) which supposedly can decode qr codes from images by simply providing a path like this: import sys, qrcode d = qrcode.Decoder() if d.decode('out.png'): print 'result: ' + d.result else: print 'error: ' + d.error So I simply installed it using sudo pip install pyqrcode . The thing I find strange about the example code above however, is that it only imports

I have a mysql database which contains some images. I receive the data from a php file: php: $result[$key]['image'] = based64_encode($resultArray[$key]['image']); Now with a Json file, I get something like this: Json: {"image":"\/9j\/4Q\/+RXhpZgAATU0AKgAAAAgACgEPAAIAAAAGAAAAhgEQAAIAAAAKAAAAjAESAAMAAAABAAYAAAEaAAUAAAABAAAAlgEbAAUAAAABAAAAngEoAAMAAAABAAIAAE... I have my swift project and want to decode the image into a UIImage, so far I have no idea how to decode the image. I have the following. Swift: Alamofire.request(.GET, url).responseJSON { (response) -> Void in if let JSON = response

I'm trying to decode encoded long dash from numeric entity to string, but it seems that I can't find a function which can do this properly. The best that I found is mb_decode_numericentity(), however, for some reason it fails to decode long dash and some other special characters. $str = '–'; $str = mb_decode_numericentity($str, array(0xFF, 0x2FFFF, 0, 0xFFFF), 'ISO-8859-1'); This will return "?". Anyone knows how to solve this problem? The following code snippet (mostly stolen from here and improved) will work for literal, numeric decimal, and numeric hexa-decimal entities: header("content

Apparently jQuery has the ability to decode a given object or string into a JSON object. However, I have a JS object that I need to POST back to the server and I find no utility in jQuery that wraps the JSON.stringify() function. That function is found in Chrome, Safari 4, FF3.6, and IE8 but is not found in earlier browsers. I can use it natively in the browsers that support it, but otherwise am forced to fall back to using Crockford's JSON scripts. Is there some built-in with jQuery that handles JSON encoding and decoding that takes the place of the Crockford scripts? You might want to check

I am using Html.fromHtml(STRING).toString() to convert a string that may or may not have html and/or html entities in it, to a plain text string. This is pretty slow, I think my last calculation was that it took about 22ms on avg. With a large batch of these it can add over a minute. So I am looking for a faster, performance built option. Is there anyway to speed this up or are there other decoding options available? Edit: Since there doesn't appear to be a built in method that is faster or built for performance specifically, I will reward the bounty to anyone that can point me in the
