I replace [imagePicker setSourceType:MAImagePickerControllerSourceTypeCamera]; to [imagePicker setSourceType:MAImagePickerControllerSourceTypePhotoLibrary]; in initButton function. Image in photo is detected not look like image that capture from camera and wrong crop

Would be great to use this as an alternative to UIImagePickerController and would be awesome to work in Universal.

First of all, thank you for this wonderful library! I am trying to implement it, but everytime the captureSession start running, or the image is cropped, I get a memory warning (on both iPhone 4s and 5) and often some crashes. The normal RAM usage is around 2-3 MB, when the MAImagePickerController is called the memory jumps to 32MB and then to over 90 when the image is cropped.

Hi, I just downloaded this project on my newest Xcode 4.6. I built it for iOS 5.0 and tested it out on iPhone 4S running iOS 5.0 but as soon as the app is launched I get this error.

Does this mean that this project only supported on ios6 ?

The example project doesn't include 64 bit support. How can I do that? If I add 64 bit architecture then I get compile errors left and right.

Using this control I am unable to submit a binary to app store.

Hi, I am using this project but I need the only cropper like this.
The main issue with this is it's not releasing memory after cropping and it increases regularly. This issue occurs more frequently in a high-end device like 6s Plus, 7 Plus etc and sometimes I get rotated (90 degrees) image.
Can you please suggest how to use the only cropper, because you used open cv for image cropping.

First thanks for your MAImagePickerController-of-InstaPDF code. Its use full for document capture. I have tested in this code working fine. I have changed camera heightand x position in the below code
" CGRect layerRect = CGRectMake(0, 150, self.view.bounds.size.width, self.view.bounds.size.height - 220);"
then i have captured image then see view page it will show full size . i means its not captures image with camera height size. Can you please how to i will resolve this . Please help me. Waiting for your message

It worked really well. Thanks a lot. But when I did some OCR on the documents by Tesseract, the results were really weird (as it still showed up perfectly on ImageView control).
I decided to save the image before any image processing (right after it's taken in MAImagePickerController) then did OCR reading, it worked again!
I think there must be something in the image processing section that I haven't figured it out.
It also works with the final adjusted image if I go to Photos, do some minor edits and press "Save".

Please forgive my lack of skills. Thanks again for your fantastic work!

my app consumes 80 MB above memory after perspective correction. After logging,i found image size was approximately doubled (original size:1936X2592 and perspective corected size:2566X3494). This consumed memory was not relased completely ,only release upto 50MB and internally release somtimes only. So memory usage was summed up for each image's perspective correction and app crashes in device with 512MB ram.Reason was below operation. I don't understand reason to use these operations.

CGFloat w1 = sqrt( pow(anchorPts[2].x - anchorPts[3].x , 2) + pow(anchorPts[2].x - anchorPts[3].x, 2));
CGFloat w2 = sqrt( pow(anchorPts[1].x - anchorPts[0].x , 2) + pow(anchorPts[1].x - anchorPts[0].x, 2));

CGFloat h1 = sqrt( pow(anchorPts[1].y - anchorPts[2].y , 2) + pow(anchorPts[1].y - anchorPts[2].y, 2));
CGFloat h2 = sqrt( pow(anchorPts[0].y - anchorPts[3].y , 2) + pow(anchorPts[0].y - anchorPts[3].y, 2));

CGFloat maxWidth = (w1 < w2) ? w1 : w2;
CGFloat maxHeight = (h1 < h2) ? h1 : h2;

Finally i figure out this was causing memory problem and app crashes..I changes size of perspectively corrected image to original image size. And memory reduces by half. and also app don't crashes.Changes I made

• (void)correctPerspective{
  // Define the destination image
  cv::Mat original = [OpenCV cvMatFromUIImage:self.pickedImg];

  CGFloat scaleFactor =[self.imgDoc contentScale];
  vector anchorPts;

    CGPoint pt=[boundary.allPoints[0] CGPointValue];
     anchorPts.push_back(Point2f(pt.x/scaleFactor,pt.y/scaleFactor));
  
    pt=[boundary.allPoints[2] CGPointValue];
    anchorPts.push_back(Point2f(pt.x/scaleFactor,pt.y/scaleFactor));
  
     pt=[boundary.allPoints[4] CGPointValue];
    anchorPts.push_back(Point2f(pt.x/scaleFactor,pt.y/scaleFactor));
  
    pt=[boundary.allPoints[6] CGPointValue];
    anchorPts.push_back(Point2f(pt.x/scaleFactor,pt.y/scaleFactor));
  

  cv::Point2f src[4], dst[4];
  src[0].x = anchorPts[0].x;
  src[0].y = anchorPts[0].y;
  src[1].x = anchorPts[1].x;
  src[1].y = anchorPts[1].y;
  src[2].x = anchorPts[2].x;
  src[2].y = anchorPts[2].y;
  src[3].x = anchorPts[3].x;
  src[3].y = anchorPts[3].y;

  dst[0].x = 0;
  dst[0].y = 0;
  dst[1].x = original.cols - 1;
  dst[1].y = 0;
  dst[2].x = original.cols - 1;
  dst[2].y = original.rows - 1;
  dst[3].x = 0;
  dst[3].y = original.rows - 1;

  cv::Mat undistorted= cv::Mat( cvSize(original.cols,original.rows), CV_8UC1);

  cv::warpPerspective(original, undistorted, cv::getPerspectiveTransform(src, dst), undistorted.size());

  original.release();

  finalImg=[OpenCV UIImageFromCVMat:undistorted];
  undistorted.release();

}

Hello,

in your Readme you're missing the 'MediaPlayer' Framework as a dependency. Otherwise compiling will break with an error for MPVolumeView.

Only a small "error", but it would complete your framework dependency list.

Hi,
there is a little issue on iPhone 5 working with Images.xcassets catalog. The grid image didn't appear on my iPhone 5.

I modified the file MAImagePickerController.m from:

gridImage = [UIImage imageNamed:@"[email protected]"];

to:

gridImage = [UIImage imageNamed:@"camera-grid-1136"];

And it works.
bye

P.S. Thank you for you code Maximilian ;-)

I get the following compile error when I do Xcode recommended upgrade

No architectures to compile for (ONLY_ACTIVE_ARCH=YES, active arch=arm64, VALID_ARCHS=armv7 armv7s).
