The overlay utility displays the required information to define overlay specifications. You can type appropriate values and press the Enter key to set the overlay specifications. You can change overlay specifications of the existing overlay, or you can create a new overlay based on the existing source overlay by changing it. Conflicts can occur between previously defined elements and changed overlay specifications in the same source overlay. This function is usually preferred in the following cases. When you try to reduce the overlay size from the previously defined values, some overlay elements may be positioned outside the newly defined overlay. The overlay size is always measured from the origin, the top-left corner of the overlay. For example, the overlay elements placed near the right edge or bottom of the previous overlay may be positioned outside the newly defined overlay. In this case, elements are deleted if their positions extend beyond the overlay boundaries. The overlay utility displays the confirmation display when such a situation occurs to let you enter the delete element operation or cancel the change overlay specifications operation. See “Confirm Delete of Elements” on page 72 for more information. The overlay utility allows you to change the unit of measure in the overlay specifications between inches and centimeters. The defined numbers in each element do not change. Therefore, some elements are positioned outside the overlay when the number specified for the size exceeds the possible maximum value for the unit. Also some values may exceed the lower limit of parameters such as module width. The overlay utility allows you to change the printer type in the overlay specifications. The overlay utility checks the compatibility between previously defined overlay elements with the newly specified printer type. If the overlay utility finds any mismatched elements, the overlay utility displays the confirmation display and lists these elements on the display. You can then delete the elements or cancel the change overlay specifications. v Changing the printer type v Changing the unit of measure v Making the overlay size smaller Note: The change operation is similar to the create operation. The only difference is that the previously entered parameters are already placed in each field when the display appears. See “Define Overlay Specifications” on page 66 for the description of each parameter. Change Overlay Specifications 70 AFP Utilities for iSeries: User’s Guide
