Here are the steps to search for text signatures within the document with GroupDocs.Signature:
- Create new instance of Signature class and pass source document path as a constructor parameter.
- Instantiate the TextSearchOptions object according to your requirements and specify search options.
- Call Search method of Signature class instance and pass TextSearchOptions to it.
This example shows how to make advanced search for Text signature in the document.
using (Signature signature = new Signature(sample.pdf))
{
// setup search options
TextSearchOptions searchOptions = new TextSearchOptions()
{
// specify special pages to search on
AllPages = false,
// single page number
PageNumber = 1,
// setup extended search in pages setup
PagesSetup = new PagesSetup() { FirstPage = true, LastPage = true, OddPages = false, EvenPages = false },
// specify text match type
MatchType = TextMatchType.Exact,
// specify text pattern to search
Text = "John Smith"
};
// search document
List<TextSignature> signatures = signature.Search<TextSignature>(searchOptions);
// output signatures
foreach (TextSignature textSignature in signatures)
{
if (textSignature != null)
{
Console.Write($"Found Text signature: {textSignature.SignatureImplementation} with text {textSignature.Text}.");
Console.WriteLine($"Location at {textSignature.Left}-{textSignature.Top}. Size is {textSignature.Width}x{textSignature.Height}.");
}
}
}
