Use PDF redaction filters Leave feedback
On this page
You can combine PageRangeFilter and PageAreaFilter in one set to limit a redaction to an area on a specific page (or slide). Assign the filters array to the Filters property of ReplacementOptions. The same approach applies to PDF and to other formats that support page filters.
The following example demonstrates how to apply redaction to the bottom half of the last page in a PDF document.
final Redactor redactor = new Redactor("Sample.pdf");
try
{
// Get the actual size information for the last page:
IDocumentInfo info = redactor.getDocumentInfo();
PageInfo lastPage = info.getPages().get(info.getPageCount() - 1);
ReplacementOptions options = new ReplacementOptions("[secret]");
options.setFilters(new RedactionFilter[] {
new PageRangeFilter(PageSeekOrigin.End, 0, 1),
new PageAreaFilter(new java.awt.Point(0, lastPage.getHeight()/2),
new java.awt.Dimension(lastPage.getWidth(), lastPage.getHeight()/2))
});
RedactorChangeLog result = redactor.apply(new ExactPhraseRedaction("bibliography", false, options));
if (result.getStatus() != RedactionStatus.Failed)
{
redactor.save();
}
}
finally { redactor.close(); }
