Tesseract OCR iOS 1.5 (iOS7 ready)

Tesseract OCR iOS is a Framework for iOS5+.

It will help you to use OCR in a iOS project. Easy and fast.

Template Framework Project ================= You can use the "**Template Framework Project**". It's a starting point for use the Tesseract Framework. It's iOS7 ready!

Alternatively you can create a New Project like explained below.

New Framework Project

Add the framework "TesseractOCR.framework" (you can drag&drop it) from the Products folder in this repo, to your XCode Project under the frameworks folder.

If you are masochist :) you can generate your TesseractOCR.framework building the TesseractOCRAggregate target.

• If you are using iOS7 or greater, link libstdc++.6.0.9.dylib library (Your target => General => Linked Frameworks and Libraries => + => libstdc++.6.0.9)

• Go to your project, click on the project and in the Build Settings tab add -lstdc++ to all the "Other Linker Flags" keys.

• Go to your project settings, and ensure that C++ Standard Library => Compiler Default. (thanks to https://github.com/trein)

• Import the tessdata folder under the root of your project. It contains the "tessdata" files. You can add more tessdata files copyng them here.

• Import the header in your classes writing #import <TesseractOCR/TesseractOCR.h>

Now you can use Tesseract class like explained here: https://github.com/ldiqual/ tesseract-ios

How to use =================

ex. from https://github.com/ldiqual/tesseract-ios but using the "TesseractOCR.framework"

#import <TesseractOCR/TesseractOCR.h>

Tesseract* tesseract = [[Tesseract alloc] initWithDataPath:@"tessdata" language:@"eng"];
//language are used for recognition. Ex: eng. Tesseract will search for a eng.traineddata file in the dataPath directory. 
//eng.traineddata is in your "tessdata" folder.

[tesseract setVariableValue:@"0123456789" forKey:@"tessedit_char_whitelist"]; //limit search
[tesseract setImage:[UIImage imageNamed:@"image_sample.jpg"]]; //image to check
[tesseract recognize];

NSLog(@"%@", [tesseract recognizedText]);

Set Tesseract variable key to value. See http://www.sk-spell.sk.cx/tesseract-ocr-en-variables for a complete (but not up-to-date) list.

For instance, use tessedit_char_whitelist to restrict characters to a specific set.
