Phased rollout

This version of the software is currently available only to early adopter SaaS customers as the first step in our phased rollout. Click here to view an earlier version.

Creating and modifying image objects

An image object is an image stored in the AR System server  database with information defining the image as a AR System server  object. The image object type appears in the AR System Navigator pane at the end of the All Objects list (see the following figure).

You can use images as backgrounds for form views and certain field types, including buttons, panels, and cell-based tables. To use the same image in multiple locations, such as the background of related forms, you do not need to store a copy of the image in the display properties of each form view or field that uses the image. Instead, store the image once as an image object, and include it by reference in form view and field display properties. Using an image object, you can also avoid the 4 MB size limit on the field display property.

AR System server  supports the following image types:

  • Windows bitmap (.bmp file extension)
  • Joint Photographic Experts Group format (.jpeg or .jpg file extensions)
  • Graphics Interchange Format (.gif file extension)
  • Portable Network Graphics format (.png file extension)

To convert existing references and image files to shared images, use the ImageExtractor.bat utility. See ImageExtractor.jar (ImageExtractor.bat).

To create an image object

  1. In AR System Navigator, expand serverName > All Objects.
  2. Right-click Images, and select New Image.
    A blank image object opens in the editing area.
  3. In the Description field, enter a description of the image.
    The description appears in the list of images in the Object Selector dialog box when you add an image to a field or form view. Enter up to 255 characters.
  4. Click Browse, and navigate to the directory containing the image.
  5. To display the available images in the directory, select the various image types from the Files of Type list.
  6. Select the image to store in AR System, and click Open.
    The image appears in the preview pane of the image object.
  7. Save the image object, assigning a unique name in the Save Image As dialog box.
    Images are indexed on the name you assign and by the image ID. Image names can have up to 255 characters.
    Although AR System server  permits backslashes in image object names, you should not to include them. To prevent attacks on your system, you should exclude unsafe characters from your web server. By default, most web servers do not allow the backslash character ( \ ) in URLs for security reasons. For example, Tomcat does not allow backslashes in URLs unless you set a parameter to permit them. If your system uses such a web server, images whose object name contains backslashes might not appear in your browser.

To open an image object

  1. In AR System Navigator, expand serverName > All Objects.
  2. Double-click Images.
  3. From the Images list, double-click the image object to open.

To save an image to a file outside  AR System server

  1. Open the image object, and then click Save to Disk.
  2. Navigate to the directory where you want to save the file.
  3. Enter an appropriate file name, and then click Save.

To rename an image object

  1. In AR System Navigator, expand serverName > All Objects.
  2. Double-click Images.
  3. Right-click the image to be renamed, and then select Rename.
  4. Enter the new name, and then save the image object.
    You cannot rename an open object in Developer Studio . If a warning indicates the object has an open editor, close the image and repeat these steps.

To delete an image object


Deleting a shared image object removes it from all form views and fields. You cannot undo this operation in Developer Studio .

  1. In AR System Navigator, expand serverName> All Objects.
  2. Double-click Images.
  3. Right-click the image to be renamed, and then select Delete.
  4. Confirm the deletion when prompted.
  5. In the second confirmation dialog, specify whether to remove references to the image from the display properties of fields and objects.
    • Click Yes to remove the reference from the listed fields or objects.
    • Click Yes to All to remove all references to the image.
    • Click No to retain the reference in the listed field or object.
    • Click No to All to retain all references to the image. 
      If you retain a reference, the image object name stays in the display property, and you can create another image object with the same name to restore the reference.
