Images

This section will show you how to use images within your application, whether you want to reuse images provided with Mojo or create your own. There is a summary of the types of images provided with Mojo, and general guidelines on how to incorporate them into your application. You will need to refer to the SDK to see the individual images referenced here; there are too many to include here, and new ones are added with each SDK release.

You will also find design and technical guidelines here that will help you create your own custom images.

There are dozens of images provided with the Mojo framework. Look in the framework/images directory and you’ll see a long list of PNG images, which are used as backgrounds, widget components, icons, and in various parts of the System UI. You are free to use any of the images in your application, but you should use them in a manner that is consistent with their use in the System UI or Palm applications.

Note

A key UI principle is that consistency enhances ease of use. If your application uses visual images differently than what the user expects, your application will be perceived as harder to use.

Images are structured according to the intended use case:

Standard image

A single image within a single file for conventional image use with img tags or similar cases.

Multistate image

Multiple images within a single file used to combine multiple button states (e.g., pressed and unpressed states) or in a filmstrip animation sequence for activity indicators ...
