* This exporter uses an absolute positioned layout and currently there is a single special
* configuration that can be applied to a PPTX
* exporter instance (see {@link net.sf.jasperreports.export.PptxReportConfiguration})
* to configure its behavior: one can ignore hyperlinks in generated documents if they are
* not intended for the PPTX output format. This can be customized using either the
* {@link net.sf.jasperreports.export.PptxReportConfiguration#isIgnoreHyperlink() isIgnoreHyperlink()}
* exporter configuration flag, or its corresponding exporter hint called
* {@link net.sf.jasperreports.export.PptxReportConfiguration#PROPERTY_IGNORE_HYPERLINK net.sf.jasperreports.export.pptx.ignore.hyperlink}.
*
* It supports font mappings, batch mode exporting, and filtering
* out content using exporter filters.
*
* Documents produced using this exporter can be generated in the great majority of the
* samples shipped with the JasperReports project source files, where the pptx Ant task is
* defined.
