Creating page groups when white space is found

You can create page groups when white space is found in an area. White space does not contain IOCA (Image Object Content Architecture) image data. As an alternative, you can create page groups when IOCA image data is found in an area.

A white space trigger is white space that occurs in a consistent location on the first page of all page groups. You define the start of each page group with the trigger.

If you create page groups using triggers, all existing page groups that are defined in the AFP file itself are ignored.

To create page groups when white space is found:
  1. In AFP Visual Environment, open a sample AFP file that contains the white space that you want to use to trigger page groups. Then click Mode ⇒ AFP Indexer.
  2. To create the area, position your cursor at a corner of the area that contains the white space that you want to use to trigger page groups. While pressing the left mouse button, draw a box that includes the white space.
  3. Right-click anywhere on the page and click Create White Space Trigger..

    You see the Trigger on White Space window.

  4. Type a descriptive name for the white space trigger in the WS Trigger definition name field.
  5. Choose when to start a page group:

    • The pels found option starts a new page group when the bounded area contains IOCA image data.

    • The pels not found option starts a new page group when the bounded area does not contain IOCA image data.

      Note: Text is not IOCA image data.

  6. Optional: Change the origin (top-left corner) and size of the bounded area in these fields. Decimal values (such as 2.5) are allowed. Specify the origin and size in inches or millimeters.
    X position
    The horizontal distance of the left side of the area measured from the left side of the logical page (not the physical sheet of paper).
    Y position
    The vertical distance of the top of the area measured from the top of the logical page (not the physical sheet of paper).
    Width
    The horizontal width of the area.
    Height
    The vertical height of the area.
    Note: If you rotated the AFP file using the Rotate by 90o option on the View menu, measure the X and Y positions from the top-left corner of the logical page in the unrotated view.
  7. Click OK.

    In the left pane and in the bottom pane, you see the page groups that have been defined based on the trigger. You also see the pages that are included in each page group.

  8. Verify that the correct page groups have been created:
    1. Check that the number of pages is correct in each page group.
    2. Select page groups in the left pane to see the first page in a few of the page groups and verify that the correct boundaries were created.
    3. If the page groups are incorrect, click Tools ⇒ Modify Definitions to modify or delete the trigger.
      The trigger is listed as a Page Group Definition under Start Page Group Triggers .
