Chapter 3-7: Output Processes
Scrolling Output Image Specifications
The scrolling output image overlay is shown in Figure 3-7-9:
The scrolling output image overlay contains the following fields:
- Img No
Displays a sequence number that is defaulted by APPX. The image number uniquely identifies each alternate image for the frame and is referenced when determining which image, if any, is to display. The first image that is defined in add mode is assigned alternate image number 1, and additional images are assigned a number equal to the highest existing image number, plus 1. The default number can be overridden, but must be unique within the frame. Refer to the Images section in Chapter 3-1 for a discussion of alternate images.
- Descriptive
Identifies this alternate image. This field is used for documentation purposes only.
- Size—Row/Col
Designates the number of rows and columns that comprise the displayed image. The image cannot be larger than the frame to which it belongs. If blank, the size of the image defaults to the size of the frame. The default is blank. See Frame/Image Positioning in Chapter 3-2 for more information.
- Extra Lines
Indicates a number of additional rows to add to the size of the image. For scrolling frames only, APPX computes the composite image size based upon the image size and the Extra Lines entry.
- Compress Type
Indicates whether or not to suppress blank lines in an image and, if so, the type of lines to compress. The Compress Type options are:
- NONE. Do not compress.
- EMBEDDED. Compress embedded blank lines. (However, the image still occupies the full number of rows.)
- TRAILING. Compress trailing blank lines.
- BOTH. Compress embedded and trailing blank lines.
The default is NONE.
- Opts
Are indicators that are present whenever documentation (T), rules (R) or additional attributes (AA) have been defined for this image.
Both the scrolling and non-scrolling output image overlays contain the following options as described in the corresponding sections:
