DISPLAY and Printer Dependencies on UNIX
■ Surface resolution when REPORTS_DEFAULT_DISPLAY=YES.
■ Removal of the printer dependency.
If, when generating report output, there is no valid printer queue available (not found
from TK_PRINTER,ORACLE_PRINTER,PRINTER, or uiprint.txt), the surface
based on screenprinter.ppd will be created and used to get font information. You
can modify the Fonts section of screenprinter.ppd to include new fonts, and
modify the DefaultResolution field to change the resolution
(DefaultResolution is 96).
The font look up algorithm on UNIX is:
if a valid printer available then
look up font information from the printer
else
create a screenPrinter surface
look up font information from ScreenPrinter
if ScreenPrinter creation fails then
REP-1800 : Formatter Error if REPORTS_DEFAULT_DISPLAY is set
else
use Screen Fonts
3.7.2 Advanced Imaging Support
Note: If you do add new fonts, ensure that the new AFM files are
placed in the AFM directory.
Note: In certain multi-byte languages like Chinese, you may want
to use screen fonts. However, this would necessitate setting the
DISPLAY variable for running the report.
To revert to DISPLAY and use screen fonts (old font look up
algorithm):
■ Set REPORTS_DEFAULT_DISPLAY=NO
■ Remove the screenprinter.ppd entry in the
uiscreenprint.txt file.

The quality of images contributes considerably to the overall appearance of a report,
particularly for a Web report. You may prefer different image formats in your report
output depending on the needs of your project. For example, an aeronautical firm
might prefer the higher quality of JPEG or PNG images in their Web reports instead of
GIF images. On the other hand, if you are building a Web portal, you might prefer GIF
images because of their smaller size and faster download. Similarly, you may wish to
import images of these various formats into your report.
Depending on the format of your output, you may choose from a variety of formats for
your images.
