Overview

ProcessMaker Mobile features the image control, which lets you take a picture using the camera of a smartphone and save this picture into a Dynaform, or upload a picture from the smartphone's current gallery.

Resizing for Uploaded Images

Available Version: As of ProcessMaker Mobile 2.2.5

Uploaded images resize the width of landscape images to 1080px and are scaled accordingly. Portrait images also resize height to 1080px and are scaled accordingly. The compression ratio used when resizing is 60%.

To use it, simply drag and drop the control onto the Dynaform.

Properties

The image control properties can be found under the Mobile controls tab after clicking the image control in the Dynaform, which are shown in the image below.

Property Description
Type Shows the field name, in this case imageMobile. (read only)
ID

[Required]

Control unique identifier. The control ID is automatically filled in with "ControlTypexxxxxxxxxx", where "xxxxxxxxxx" represents the correlative number of the control inside the designer. In this case imageMobile0000000001.

Label Allows you to change the field label in the Dynaform.
Input Document Link an Input Document to the control.
Hint Used to show a help message when the field is rendered. It is shown when the pointer of the mouse hovers over the ? icon.
Required By checking this option, a red asterisk is added next to the label to indicate that the field is required. This property does not allow the end user to submit the Dynaform until an image is uploaded.
Required field error message After checking the required property, this property is enabled to fill in a customized message.
Enable camera By checking this option, the mobile app allows you to use the device's camera to take a picture.
Enable gallery By checking this option, the mobile app allows you to choose a picture from the device's gallery.
Available offline

Available Version: As of ProcessMaker 3.4.5 and ProcessMaker Mobile 2.1.0

By checking this option, the mobile app allows you to work an image field while working offline.

Input Document

It is possible to associate an Input Document with an image control through the Input Document property.

This means that the photo taken or uploaded with the control can be displayed at a later step inside an input document. One advantage of associating a photo control with an input document is that the input document interface can be used to view all the photos taken or uploaded in the case, as well as deleting and adding new versions if the user has the correct Process Permissions and versioning is enabled.

Note that the file size, extension and other properties configured in the input document won't apply to the photo file recorded or uploaded to the photo control. Nevertheless, photos will inherit the destination path and the tag properties from the input document.

Enable Camera

Check the Enable camera property to allow you to use the device's camera to take a new picture. If this option is unchecked, you are not able to take a picture with their device's camera to enter into the Dynaform.

Enable Gallery

Check the Enable gallery property to allow you to use the device's gallery to choose a picture. If unchecked, the mobile app won't allow you to choose images from the gallery.

If Enable camera and Enable gallery options are checked, you have the option to choose between the camera or the gallery in a pop up dialog.

The app uses web-kit tools exclusively for Android and iOS to display the form fields, thus forms are not rendered the same way as in the web edition (in the preview of the designer or when running cases). The screenshot below shows the Image control running in the mobile app.

This is what the Image control looks like when opening a case in the web edition after saving the image in the mobile app.
