Using the Image Annotation Control
The Image Annotation control lets you annotate photos on your iOS device. You can display the annotated image on a form or save it to a SmartObject for later use. This control must be configured at form design time with rules that handle the events and data captured using the control. For information on configuring the control at form design time see the Image Annotation Control topic in the K2 smartforms User Guide.
The Image Annotation control is only available in a SmartForm, there is no other way to access it in K2 Mobile.
Tapping the annotation control on a SmartForm lets you either choose an exiting image from the photo library or take a new photo with the device.
| Icon | Description |
|---|---|
|
The pen icon shows the color swatch bar on the bottom of the screen. Drag over it to select the pen's color. Draw on the image to make annotations. |
|
The resize icon allows you to zoom the image with a pinch gesture and pan around the zoomed image with a single finger drag. Double tapping the icon resets the image zoom level. |
|
The erase icon removes the last stroke of your annotation with a single tap, or all annotations with a tap and hold. |
You can cancel the image annotation by tapping the X on the top left of the screen. Tap Done to store the image annotation and return to the form.
Considerations
- When you select multiple images via the Image Annotation control, the images are only uploaded and not annotated. Best practice is to upload and annotate one image at a time via the Image Annotation control.
