ChangeLog(31/7/2015)

• Crop Feature Tweaked for more control in horizontal and vertical dragging.
• NOW , Landscape and Potrait both images can be used in scanning the objects in images.
• Addded Image Filters (Gray Scale, Magic Color ,Black and White)
• Left Rotate and Right Rotate

Framework Add the Frameworks to see the Demo

Convert in swift 3

Hello, nice work !

but can i transform this app in swift 3 ?

thanks for your reply.

Data Encryption

Dear ,

Thank you for your support.

I just want to know that is this library using any Data Encryption processing (like "AES", "3DES", "RSA", "DH" etc), if yes could you please give some information about it, if possible.

Thanks in advance.

Any plan to upgrade to new Xcode 10 ? Or maybe migrate to Swift 4 ?

Hi, I would like to know if have any plan to upgrade to new Xcode 10 ?
Also I would like to know any possibility to migrate to Swift 4 ?

Thanks!

Can not recognize some image

Hi, Thanks to your great project. It works fine for normally rectangle image. But if there's something overlays it a little bit, it will recognize fail, like below image:

And I tried on camscanner app, it works!
Would you please tell me how to fix this? thx~

-- Getting above error, i am not getting , how to resolve this issue..
Anyhow if i resolve above issue, i am getting TesseractOCR framework not found issue even framework were added..

hello, I have a trouble

MMCamScanner[35084:1889935] This application is modifying the autolayout engine from a background thread after the engine was accessed from the main thread. This can lead to engine corruption and weird crashes.

也是第一次允许安装的时候，点击拍照，出现，界面卡顿，全是黑色的，出现不了相机的界面

我该怎么办？？？？求帮助！！！！！

How to implement into a Swift Project

Hey there :) Hoe can I implement this project into my existing Swift Project?

Error on captureStillImageAsynchronouslyFromConnection

[_stillImageOutput captureStillImageAsynchronouslyFromConnection:videoConnection completionHandler: ^(CMSampleBufferRef imageSampleBuffer, NSError *error)

Error Domain=AVFoundationErrorDomain Code=-11800 "The operation could not be completed" UserInfo={NSUnderlyingError=0x174056170 {Error Domain=NSOSStatusErrorDomain Code=-16800 "(null)"}, NSLocalizedFailureReason=An unknown error occurred (-16800), NSLocalizedDescription=The operation could not be completed}

When is the working "Pod" version is expected?

Currently after cloning it is needed to convert to new swift syntax and add 3rd party libs. I saw there is an announcement of supporting pods. When is that expected to be (I want to start with evaluating project).

Thanks! It looks like a great work by the way!

How to download and install

Please advice how to download and install TesseractOCR and OpenCV....please give step by step
I try but getting error #import <TesseractOCR/TesseractOCR.h> and #include <opencv2/imgproc/imgproc.hpp> file not found

Getting crash when failed to identify edges.

Hi, Sometimes app getting failed to identify the edge and its getting crash. In Log is displays Missing 1, Missing 2 ( NSLog(@"MISSING %i", i);), then its crash. Below I have included Log.

The app was working fine before updating to swift2.3 to swift 3 (i have created bridge header) and Xcode to 8.3.2.

Installation fails

I have added both frameworks. There might be lot of changes in new iOS versions. Can you look into the step of installation and make it easy for us to integrate your awesome lib ? :). Have spent lot of time , but cant get it to working. Thanks!

Swift Compile Error

I'm using xcode 8.2.1
but your code is not supporting my devices it's not showing the simulators. I changed deployment target also.

Command /Applications/Xcode 8.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/swiftc failed with exit code 1

Command /usr/bin/ditto failed with exit code 1

Please help me ASAP. I have an urgent requirement.

Thanks,

Is this project include color magic filter ?? I could not find it anywhere

'opencv2/imgproc/imgproc.hpp' file not found

Even I added frameworks still cannot be compiled. Your documentation definitely is not enough to run your example. Are you sure it's working?
