REPORTS_GRAPH_IMAGE_DPI
environment variableThis environment variable specifies a dots per inch (DPI) value for graphs
output to a PDF file or a printer. The default value for this environment variable
is set at 72
DPI to minimize the time taken to generate the report
as well as to reduce the report file size.
If you specify a value higher than 72
DPI, you will see an improvement in the image resolution for graphs sent
to a PDF file or a printer. However, this affects the time taken to generate
the report output as well as the file size.
Note: With the value of REPORTS_GRAPH_IMAGE_DPI=250
:
The time taken to generate a report with a graph increases 5 to 6 times when compared to the time taken to generate the same report with the value set to 72 DPI.
The PDF file size also increases 5 to 6 times.

On Windows, use the registry to specify the value. On Unix/Linux, set the
environment variable in reports.sh
.
When you set a higher DPI value, you may also need to change the JVM heap
size value with REPORTS_JVM_OPTIONS
to avoid the Out Of Memory
error for the JVM.
This environment variable is not supported in Oracle Reports distribution functionality, as it is specific to PDF and printer outputs only.
