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
name of that input is the ID of the Camera element, followed by "-note-data", for example
camera1-note-data.
Cropping/editing/deskewing
To allow the user to crop, edit and deskew the image after taking or selecting it, select Camera
properties, and then check Edit Image and/or Allow Deskew. Which editing options the user
actually gets and how they are presented to the user depends on the operating system of the
device. On an Android device for example, the user may be able only to crop the image, while
the user of an iOS device may select part of the image and rotate that selection.
Image format
You can set the format, quality and scaling for images that are submitted by the Camera
element. Right-click the Camera element after adding it to the form, select Camera properties
and edit the Image properties:
l
Format: The image format can be PNG or JPG.
l
Quality: Set the compression in a percentage.
l
Scale Image: Check this option to enable image scaling. Then set the maximum width
and height of images before they are sent to the server. Note that only the smallest of
these is applied and the size ratio is always maintained.
