Camera Frame

A frame is cropped by the camera frame. If you set the camera frame to full screen, Core will crop the frame by phone borders. Note that using this setting may lead to lower performance because of the huge frame size. Any changes connected to the camera frame alter the scanning process.

  • To override the default cropping frame on the camera activity provided by the scenario, set:
DocReader.shared.functionality.cameraFrame = DocReaderFrame.max
[RGLDocReader shared].functionality.cameraFrame = RGLDocReaderFrameMax;
DocumentReader.Instance().functionality().edit().setCameraFrame(DocReaderFrame.MAX).apply()
DocumentReader.Instance().functionality().edit().setCameraFrame(DocReaderFrame.MAX).apply();
DocumentReader.instance.functionality.cameraFrame = DocReaderFrame.MAX;
DocumentReader.setFunctionality({
    cameraFrame: Enum.DocReaderFrame.MAX
}, (str) => { console.log(str) }, (error) => { console.log(error) });
DocumentReader.setFunctionality({
    cameraFrame: Enum.DocReaderFrame.MAX
});
DocumentReader.setFunctionality({
    cameraFrame: Enum.DocReaderFrame.MAX
}, function (m) { }, function (e) { console.log(e); });
// Android
DocumentReader.Instance().Functionality().Edit().SetCameraFrame(DocReaderFrame.Max).Apply();

// iOS
RGLDocReader.Shared.Functionality.CameraFrame = RGLDocReaderFrame.Max;
  • Set the thickness of the document borders in the video preview (in dp):
DocReader.shared.customization.cameraFrameBorderWidth = 10
[RGLDocReader shared].customization.cameraFrameBorderWidth = 10;
DocumentReader.Instance().customization().edit().setCameraFrameBorderWidth(5).apply()
DocumentReader.Instance().customization().edit().setCameraFrameBorderWidth(5).apply();
DocumentReader.instance.customization.cameraFrameBorderWidth = 20;
DocumentReader.setCustomization({
    cameraFrameBorderWidth: 20,
}, (str) => { console.log(str) }, (error) => { console.log(error) });
