Using the Sketch Pad Control

With the Sketch Pad control, a mobile user can draw on an image or a blank canvas. The mobile user can use the Sketch Pad to circle problem areas, leave notes, draw diagrams, or cross out irrelevant details. A Form Designer can set up a Sketch Pad question to collect multiple images or drawings.

This topic describes how to launch the Sketch Pad control and lists the tools and options available to the mobile user.

Launch the Sketch Pad

To begin, select Launch Sketch Pad (on an Android device) or Tap to Select Photo (on an iOS device).

To answer a Sketch Pad question, a mobile user can:

• Take a photo with the device camera to sketch on.

• Choose a photo from the camera roll to sketch on.

• Choose a photo from local files or a cloud service, such as OneDrive, Dropbox, or Google Drive.

• Choose a satellite map image to sketch on.

• Sketch on a blank canvas.

• Sketch on a resource image provided by the Form Designer.

The options available to the mobile user depend on how the question is set up in the Form Builder The Form Builder is the tool that form designers use to create forms. In the Form Builder, accessed from the TrueContext Web Portal, form designers can add and edit pages, sections, and questions, as well as attach data destinations and configure the form's settings..

Tip:When a mobile user submits a record, TrueContext converts each Sketch Pad attachment to a compressed JPEG image. This might lead to a loss in quality if the original image is in another format like PNG or BMP. For the best image quality in submitted records, attach JPEG images.
