How to capture long image merged from small captured images

Today we discuss about CameraView but this is not as you think it is a camera view to capture long image merged from small captured images as it is in Shoparoo app available on Google Play!!

This library uses CameraView from Google as the backbone of camera functionality and adds auto-support of creating long or wide images from multiple images. This library includes:

  • Built-in Camera UI and activity
  • Built-in Image Viewer with pinch-fling gestures for zoom/move/rotate etc.
  • TouchImageView with gestures support for zoom/move/rotate etc.
  • Built-in permission handling for Camera and Storage
  • Horizontal or Vertical image merging



Add this in your app’s build.gradle file:

dependencies {
  compile 'com.wajahatkarim3.LongImageCamera:LongImageCamera:1.0.1'

Or add LongImageCamera as a new dependency inside your pom.xml

Launch Camera Activity

LongImageCameraActivity.launch( myActivity );

// Launches Camea in Horizontal Merge Mode (Captured image will be wide)
LongImageCameraActivity.launch( myActivity, LongImageCameraActivity.ImageMergeMode.HORIZONTAL );

and then you will get the result image in onActivityResult() method like this:

    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);

        if (resultCode == RESULT_OK && requestCode == LongImageCameraActivity.LONG_IMAGE_RESULT_CODE && data != null)
            String imageFileName = data.getStringExtra(LongImageCameraActivity.IMAGE_PATH_KEY);
            Log.e(TAG, "onActivityResult: " + imageFileName );
