Altova MobileTogether Designer

Images can be added to the design by both the designer and the end-user, and images can be added via an URL or can be stored as Base64-encoded text in XML files. The basis of image functionality is provided by the Image control, which positions the image in the design and defines the basic properties of the image. Key mechanisms and usage are described in the sub-sections of this section.


Image Source is the property of the Image control that selects the image to display. This section describes the two types of image sources that can be used: (i) image files located by URL, and (ii) images as Base64-encoded strings.

Image Size

Base64-Encoded Images describes how to use Base64-encoded images in your design.

Exchangeable Image File Format (Exif) is a format for storing image metadata with an image. This section shows how individual pieces of Exif data can be retrieved and used in a design.

Images Chosen by the End User explains the mechanism with which the end user of a MobileTogether solution can select images that will be stored in a database. These images can be stored as image files or as Base64-encoded strings.

Transforming Images describes how to transform Base64 images (for example, resizing or rotating an image) and the issues related to transforming (loss of Exif data and memory issues on the client).

Images in Databases lists the ways in which images can be stored in databases.


These mechanisms are enabled by powerful Image actions and image-related Altova XPath extension functions.
