Note
Using the Barcode Scanner element requires the installation of the ZXing Barcode Scanner
application on Android devices. The application returns the barcode data after scanning.
Camera
The Camera element adds a group of buttons to capture or select an image. Once the image is
selected via the camera or the device's library (aka "gallery"), it is saved within the Form data.
When the form is submitted, the image is sent in a base64-encoded string format.
Buttons
By default, the Camera element adds three buttons to the form:
l
Take now: Opens the device's default Camera application to take a picture using the
device's camera. Capture OnTheGo has no impact on the device's applications, so the
features available (quality, orientation, filters) are dependent on the device itself. You can,
however, set the format, quality and scaling for images that are submitted by the Camera
element, as explained below.
l
Library: Opens the device's default library or gallery application to select a single image
that is then saved in the form data. The accessible images and navigation depend on the
device itself.
l
Clear: Removes any existing image data from the Camera element.
To omit the Take now or Library button, edit the Camera element's properties: right-click the
Camera element after adding it to the form, select Camera properties and then use the Source
drop-down to select which buttons will be available: Take, Pick from library, or both.
Annotations
Annotations can make a picture much more informative: an arrow, showing in which direction a
car was driving; a circle, where the car has been damaged... To allow the user to make
annotations, right-click the Camera element after adding it to the form, select Camera
properties, and then check Allow annotations.
Clicking (or rather, touching) the image will bring up the annotation dialog. Annotations can be
made in a Marker (semi-transparent) or Pencil (solid) style, in different colors and with different
widths.
Annotations are submitted in SVG format by a hidden input added to the Camera element. The
