Search PDF Files - C++


// Load PDF document
Document pdfDocument = new Document("source.pdf");

// Create TextAbsorber object to find all instances of the input search phrase
TextFragmentAbsorber textFragmentAbsorber = new TextFragmentAbsorber("\d{4}-\d{4}"); // like 1999-2000

// Set text search option to specify regular expression usage
TextSearchOptions textSearchOptions = new TextSearchOptions(true);
textFragmentAbsorber.setTextSearchOptions(textSearchOptions);

// Accept the absorber for first page of document
pdfDocument.getPages().accept(textFragmentAbsorber);

// Get the extracted text fragments into collection
TextFragmentCollection textFragmentCollection = textFragmentAbsorber.getTextFragments();

// Loop through the fragments
for (TextFragment textFragment : (Iterable<TextFragment>) textFragmentCollection) {
	System.out.println("Text :- " + textFragment.getText());
	System.out.println("Position :- " + textFragment.getPosition());
	System.out.println("XIndent :- " + textFragment.getPosition().getXIndent());
	System.out.println("YIndent :- " + textFragment.getPosition().getYIndent());
	System.out.println("Font - Name :- " + textFragment.getTextState().getFont().getFontName());
	System.out.println("Font - IsAccessible :- " + textFragment.getTextState().getFont().isAccessible());
	System.out.println("Font - IsEmbedded - " + textFragment.getTextState().getFont().isEmbedded());
	System.out.println("Font - IsSubset :- " + textFragment.getTextState().getFont().isSubset());
	System.out.println("Font Size :- " + textFragment.getTextState().getFontSize());
	System.out.println("Foreground Color :- " + textFragment.getTextState().getForegroundColor());
