Search Text

Use CPDFTextSearcher class to perform text search. The search steps are as follows:

1. Create a CPDFTextSearcher object.
2. Iterate through each page and get the CPDFTextPage object.
3. Call findStart to begin searching.
4. Use findNext to iterate through search results.
5. Call findClose to end the search.

Here is an example of text search:

CPDFDocument document = new CPDFDocument();
document.open("test.pdf");

CPDFPage page = document.pageAtIndex(0);
CPDFTextPage textPage = page.getTextPage();

CPDFTextSearcher searcher = new CPDFTextSearcher();
boolean started = searcher.findStart(textPage, "PDF", 0,
        CPDFTextSearcher.PDFSearchOptions.PDFSearchCaseSensitive);

int count = 0;
CPDFTextRange range;
while ((range = searcher.findNext()) != null) {
    count++;
    System.out.println("Match " + count + ": location=" + range.location
            + ", length=" + range.length);
    System.out.println("  Text: " + textPage.getText(range));
}
searcher.findClose();
searcher.close();
textPage.close();
document.close();
}
