Usage Notes
Resolving PDF Font Issues During Cross-Platform Deployment
■ On Windows, use the registry to specify the value. On Unix/Linux, set the
environment variable in reports.sh.
■ Generating a high resolution chart will increase the PDF file size relatively and the
time taken to generate the PDF file/printer output.
■ When you set a DPI value greater than 250 and your chart is bigger than 5"x5"
(approximately), you may also need to change the JVM heap size value via
REPORTS_JVM_OPTIONS to avoid the Out Of Memory error for the JVM. See
REPORTS_JVM_OPTIONS, for more information on setting the JVM options
■ To revert to the old behavior, set the value of this environment variable to 72 DPI.
■ This variable is currently not supported in Oracle Reports distribution
functionality as this is specific to PDF, PS, and printer outputs only.
6.2 Resolving PDF Font Issues During Cross-Platform Deployment
There are font and text alignment issues when you design a report (single byte or
multibyte) on the Windows platform and deploy it on a UNIX platform. The reason is
that the font handling and windowing system are completely different across the two
platforms.
6.2.1 Designing and Deploying the Report on the Same Platform
Your report is designed and deployed on the same platform, e.g., Windows:
■ There should be no font or text alignment issues in the PDF file.
■ If the PDF file is generated with font subsetting enabled, then the PDF file can be
viewed in the same manner across platforms.
6.2.2 Designing the Report on and Deploying it on UNIX
Your report is designed on the Windows platform and deployed on the UNIX
platform.
(Windows) You use the TrueType fonts located in the Windows machine. Oracle
Reports queries the font information from the Windows system for formatting the
report.
(UNIX) When this report is sent to PDF on Solaris or any other UNIX platforms, there
are two stages:
1. Oracle Reports renders the font metrics information for the fonts and uses this
information to format various objects in the report.
Note: Oracle Reports renders the font metrics information from
the AFM files mentioned in the printer’s PPD file.
2. Oracle Reports then looks for the entries in the [PDF] section of the uifont.ali
file. For font subsetting, Oracle Reports refers to the [PDF: Subset] section and
subsets the TrueType fonts from the given location. The subsetted fonts are then
embedded in the PDF file.
