- Instantiate the TextSearchOptions object according to your requirements and specify additional search options (if needed);
- Call Search method of Signature class instance and pass TextSearchOptions to it.
This example shows how to search for Text e-signature in the document.
using (Signature signature = new Signature(sample.pdf))
{
// setup search options
TextSearchOptions searchOptions = new TextSearchOptions()
{
// search only page with specified number
PageNumber = null,
// specify as true to search all pages of a document
AllPages = true,
// specify text to search
Text = "JS_",
// specify text math type
MatchType = TextMatchType.Contains
};
// 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}.");
}
}
}
