Getting Started with Cam.Cordova

Installation

To integrate cam.cordova into your hybrid app, follow these steps:

1. Install the cam.cordova plugin via the Cordova Command-Line Interface (CLI):

cordova plugin add cordova-plugin-camera

2. Add the necessary JavaScript file to your project's www directory:

Usage

To use cam.cordova, simply call the Camera object's getPicture method:

navigator.camera.getPicture(onSuccess, onFail, options);

Options

The options parameter allows for customization of camera behavior:

• quality: Sets the image quality (0-100)
• destinationType: Specifies the image format (e.g., "FILE_URI," "DATA_URL")
• sourceType: Selects the source (e.g., "CAMERA," "PHOTOLIBRARY")

Success and Error Handling

The onSuccess and onFail callbacks handle successful and failed attempts, respectively:

function onSuccess(imageData) {
  // Handle successful image capture
}

function onFail(error) {
  // Handle error during image capture
}

Advanced Usage

Image Editing

Cam.cordova offers advanced image editing capabilities through its saveImageDataToLibrary method:

navigator.camera.saveImageDataToLibrary(imageData, onSuccess, onFail, options);

Predefined Options

For convenience, cam.cordova provides predefined options:

• CameraOptions: Configures camera capture settings
• CameraPopoverOptions: Sets popover behavior (iOS only)
• DestinationType: Specifies image format
• EncodingType: Sets image encoding (JPEG, PNG)
• MediaType: Selects media type (image, video)
• PictureSourceType: Determines image source (camera, library)

Security Considerations

While cam.cordova provides extensive camera functionality, it also raises security concerns. To mitigate risks, consider these recommendations:

• Secure Image Storage: Handle captured images securely to prevent unauthorized access.
• Data Encryption: Encrypt sensitive image data to protect against data breaches.
• Access Restrictions: Implement access controls to limit who can capture and view images.
