Error handling for graphics
Use the ABNORMAL ERROR parameter to specify how the
system will handle error conditions involving graphics. If you
specified ABNORMAL ERROR=STOP in the JSL, the DP 2000
Series EPS systems do the following when they encounter an
image that is off the page:
•
Display an error message.
• Partially print the image.
• Give the operator the option to abort the job or to continue
printing and have the error added to the log.
Graphic processing modes
A graphic is handled by the software in one of the following four
modes:
•
Random mode (Move mode)
• Block mode
• Batch mode
You select the mode depending upon how the graphic is made
available for report processing, as well as your performance
requirements and disk resources.
Random or Move
mode
In Random mode (also called Move mode), a graphic is obtained
from a named disk file. The file must already exist at the start of
report processing or must be read from the input data stream
before the first record of the report text is processed. In the latter
case, each graphic is written to the disk as a permanent image
file. In Random mode, the output software reads the various
graphics for a page from their individual files.
Block mode In Block mode, a graphic is obtained from the input data stream
immediately following the textual data to be imaged on the same
page. Separate graphic disk files are not created.
A given page of a report that includes Block mode graphics may
also include either Random or Move mode graphics.
