About

TrueContext allows you to configure the Image and Sketch Pad tools to stamp data directly onto images in a form submission. This can provide additional context for the image, such as stamping the date/time an image was taken onto the image or adding a label.

Data stamping happens in the background when the form is submitted, meaning it is not visible to the mobile user, nor is the mobile user required to complete any extra steps before sending the form. Data stamping will also increase the file size of images by a small amount.

Before Using This Feature

As images/sketches can vary in size/quality between devices and settings, you should consider the following points before using data stamping:

Setting up Data Stamping

This feature is available on Image or Sketch Pad questions in the Form Builder. Toggling on Stamp Data on Images in the Properties tab will open the configuration menu:

Image Properties

Stamping this data on images draws from EXIF image metadata captured by the camera, rather than by TrueContext.

  • Date: This will stamp the image with the date/time the photo was taken; useful for forms requiring more strict compliance with date/time information.
  • Geo Location: This will stamp the image with the location the photo was taken in.
Note:
  • If you do not have EXIF data enabled on your camera or your camera does not use EXIF data, these stamp properties will not work.

  • Sketch Pad questions do not support EXIF data. When a user sketches on a background image, we save the resulting drawing in a new file. This new file does not retain the original EXIF data from the background image.

  • We recommend that you test the form on the type of device most commonly used in the field before deploying the form for use in production.
