Introduction

Welcome to the documentation for PBJVision – a comprehensive computer vision library for iOS.

Getting Started

Installation

  1. To install PBJVision, you can use CocoaPods by adding the following line to your Podfile:
    2. pod 'PBJVision'
  2. Alternatively, you can manually integrate PBJVision into your project by adding all the files in the “PBJVision” folder to your project.

Usage

To start using PBJVision, simply follow these steps:

  1. Create an instance of PBJVision in your view controller:
    2. // Swift
let vision = PBJVision()

// Objective-C
PBJVision *vision = [PBJVision sharedInstance];
  2. Set the desired camera capture quality:
    3. // Swift
vision.cameraDevice = .back
vision.cameraMode = .photo
vision.cameraOrientation = .portrait
vision.focusMode = .continuousAutoFocus

// Objective-C
vision.cameraDevice = AVCaptureDevicePositionBack;
vision.cameraMode = PBJCameraModePhoto;
vision.cameraOrientation = PBJCameraOrientationPortrait;
vision.focusMode = PBJFocusModeContinuousAutoFocus;
  3. Implement the PBJVisionDelegate protocol in your view controller:
    4. // Swift
vision.delegate = self

// Objective-C
vision.delegate = self;
  4. Start and stop capturing as needed:
    5. // Swift
vision.startPreview()
vision.startCapture()

// Objective-C
[vision startPreview];
[vision startCapture];

Features

Photo Capture

PBJVision allows capturing high-quality photos with ease:

  1. Implement the photoOutput:didCapturePhoto:error: delegate method to receive captured photos.
  2. To capture a photo, call the capturePhoto method.

Video Capture

PBJVision also provides seamless video capturing capabilities:

  1. Implement the videoOutput:didCaptureSampleBuffer: delegate method to receive captured video frames.
  2. You can start capturing a video by calling the startVideoCapture method, and stop it using endVideoCapture.

Customization

PBJVision offers various customization options for more control over your capture experience:

  • Adjust video recording settings like video codec, pixel format, and bit rate using videoBitRate, videoCodec, and videoCompressionProperties.
  • Enable or disable audio recording during video capture with enableAudioCapture.
  • Set the preview view for the camera using previewView.
  • Change the video orientation using setVideoOrientation:.
  • Manually control the focus and exposure using various methods provided by the PBJVision class.

Documentation

For detailed information on using PBJVision, refer to the official CocoaDocs documentation.
