+ZXingObjC
+=========
+
+ZXingObjC is a full Objective-C port of [ZXing](http://code.google.com/p/zxing/) ("Zebra Crossing"), a Java barcode image processing library. It is designed to be used on both iOS devices and in Mac applications.
+
+The following barcodes are currently supported for both encoding and decoding:
+
+* UPC-A and UPC-E
+* EAN-8 and EAN-13
+* Code 39
+* Code 93
+* Code 128
+* ITF
+* Codabar
+* RSS-14 (all variants)
+* QR Code
+* Data Matrix
+* Aztec ('beta' quality)
+* PDF 417 ('alpha' quality)
+
+ZXingObjC currently has feature parity with ZXing version 2.0.
+
+Usage
+----
+
+Encoding:
+
+```objc
+NSError* error = nil;
+ZXMultiFormatWriter* writer = [ZXMultiFormatWriter writer];
+ZXBitMatrix* result = [writer encode:@"A string to encode"
+ format:kBarcodeFormatQRCode
+ width:500
+ height:500
+ error:&error];
+if (result) {
+ CGImageRef image = [[ZXImage imageWithMatrix:result] cgimage];
+
+ // This CGImageRef image can be placed in a UIImage, NSImage, or written to a file.
+} else {
+ NSString* errorMessage = [error localizedDescription];
+}
+```
+
+Decoding:
+
+```objc
+CGImageRef imageToDecode; // Given a CGImage in which we are looking for barcodes
+
+ZXLuminanceSource* source = [[[ZXCGImageLuminanceSource alloc] initWithCGImage:imageToDecode] autorelease];
+ZXBinaryBitmap* bitmap = [ZXBinaryBitmap binaryBitmapWithBinarizer:[ZXHybridBinarizer binarizerWithSource:source]];
+
+NSError* error = nil;
+
+// There are a number of hints we can give to the reader, including
+// possible formats, allowed lengths, and the string encoding.
+ZXDecodeHints* hints = [ZXDecodeHints hints];
+
+ZXMultiFormatReader* reader = [ZXMultiFormatReader reader];
+ZXResult* result = [reader decode:bitmap
+ hints:hints
+ error:&error];
+if (result) {
+ // The coded result as a string. The raw data can be accessed with
+ // result.rawBytes and result.length.
+ NSString* contents = result.text;
+
+ // The barcode format, such as a QR code or UPC-A
+ ZXBarcodeFormat format = result.barcodeFormat;
+} else {
+ // Use error to determine why we didn't get a result, such as a barcode
+ // not being found, an invalid checksum, or a format inconsistency.
+}
+```
+
+Examples
+--------
+
+ZXingObjC includes several example applications found in "examples" folder:
+
+* BarcodeScanner - An iOS application that captures video from the camera, scans for barcodes and displays results on screen.
+* QrCodeTest - A basic QR code generator that accepts input, encodes it as a QR code, and displays it on screen.
+
+Getting Started
+---------------
+> As a simpler alternative to adding files directly, you can consider using [CocoaPods](http://cocoapods.org) to add ZXingObjC as a dependency.
+
+1. [Download ZXingObjC](https://github.com/TheLevelUp/ZXingObjC/tarball/master) or clone it from git: `git clone git://github.com/TheLevelUp/ZXingObjC.git`.
+
+2. Drag the ZXingObjC folder onto Xcode. Make sure "Copy items" is checked before clicking "Add".
+
+3. Selecting your project in the left sidebar, select your target, and choose the "Build Phases" tab. Under "Link Binary With Libraries", add the appropriate frameworks for your architecture:
+
+ For an iOS app:
+ * AVFoundation.framework
+ * CoreGraphics.framework
+ * CoreMedia.framework
+ * CoreVideo.framework
+ * ImageIO.framework
+ * QuartzCore.framework
+
+ For a Mac app:
+ * ApplicationServices.framework
+ * CoreMedia.framework
+ * CoreVideo.framework
+ * QuartzCore.framework
+ * QTKit.framework
+
+4. Import the ZXingObjC framework header:
+
+```obj-c
+#import "ZXingObjC.h"
+```
+
+License

+
+ZXingObjC is available under the [Apache 2.0 license](http://www.apache.org/licenses/LICENSE-2.0.html).

+When we at WRT talk about \"text,\" we are generally talking about a particular kind of readable information encoding - and readable is a complex proposition. Text may be stylized in a way we are unfamiliar with, as in blackletter - it may be interspersed with some markup we don\'t understand, such as HTML - it may be be a substitution system we aren\'t familiar with, such as braille or morse code - or it may be a system that, while technically human-readable, isn\'t particularly optimized for reading by humans, as with barcodes (although barcodes can be read).

+THROUGH THE LOOKING-GLASS
+
+By Lewis Carroll
+
+
+CHAPTER I. Looking-Glass house
+
+One thing was certain, that the WHITE kitten had had nothing to do with
+it:--it was the black kitten's fault entirely. For the white kitten had
+been having its face washed by the old cat for the last quarter of
+an hour (and bearing it pretty well, considering); so you see that it
+COULDN'T have had any hand in the mischief.
+
+The way Dinah washed her children's faces was this: first she held the
+poor thing down by its ear with one paw, and then with the other paw she
+rubbed its face all over, the wrong way, beginning at the nose: and
+just now, as I said, she was hard at work on the white kitten, which was
+lying quite still and trying to purr--no doubt feeling that it was all
+meant for its good.
+
+But the black kitten had been finished with earlier in the afternoon,
+and so, while Alice was sitting curled up in a corner of the great
+arm-chair, half talking to herself and half asleep, the kitten had been
+having a grand game of romps with the ball of worsted Alice had been
+trying to wind up, and had been rolling it up and down till it had all
+come undone again; and there it was, spread over the hearth-rug, all
+knots and tangles, with the kitten running after its own tail in the
+middle.
+
+'Oh, you wicked little thing!' cried Alice, catching up the kitten, and
+giving it a little kiss to make it understand that it was in disgrace.
+'Really, Dinah ought to have taught you better manners! You OUGHT,
+Dinah, you know you ought!' she added, looking reproachfully at the old
+cat, and speaking in as cross a voice as she could manage--and then she
+scrambled back into the arm-chair, taking the kitten and the worsted
+with her, and began winding up the ball again. But she didn't get on
+very fast, as she was talking all the time, sometimes to the kitten, and
+sometimes to herself. Kitty sat very demurely on her knee, pretending to
+watch the progress of the winding, and now and then putting out one
+paw and gently touching the ball, as if it would be glad to help, if it
+might.
+
+'Do you know what to-morrow is, Kitty?' Alice began. 'You'd have guessed
+if you'd been up in the window with me--only Dinah was making you tidy,
+so you couldn't. I was watching the boys getting in sticks for the
+bonfire--and it wants plenty of sticks, Kitty! Only it got so cold, and
+it snowed so, they had to leave off. Never mind, Kitty, we'll go and
+see the bonfire to-morrow.' Here Alice wound two or three turns of the
+worsted round the kitten's neck, just to see how it would look: this led
+to a scramble, in which the ball rolled down upon the floor, and yards
+and yards of it got unwound again.
+
+'Do you know, I was so angry, Kitty,' Alice went on as soon as they were
+comfortably settled again, 'when I saw all the mischief you had been
+doing, I was very nearly opening the window, and putting you out into
+the snow! And you'd have deserved it, you little mischievous darling!
