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. To learn how
to add Camera data to a template, see "Adding Camera data to the template" on page556.
The Camera element has a number of options, of which most can be set in the Design view.
These options are described below.
All options, including options that cannot be set via the Design view, can be set via the Source
view or in code; see "Changing default settings for widgets" on page588.
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
