How can I create annotation with searching text?

[Thanh Hai Dang]

Hi

I have a SfPdfViewer, I need to create a squareAnnotation which surrounds a text that determined by searching function.  I've refer that link, but the location is wrong. 

I saw that the pdfViewer find text function detected position exactly. 

So, how can I draw a annotation exactly with text bounds which's returned by searching function?

Thanks and best regards,

Hi TH,

Regarding display search result by SfTreeView

In .NET MAUI PdfViewer, we have support for retrieving the current search index, total searched text count in the document, and we provide the search options (whole words and case sensitive). Kindly refer to the following UG link to learn more about the search result and search options in PdfViewer.

Search Result: https://help.syncfusion.com/maui/pdf-viewer/text-search#search-result

Search Option: https://help.syncfusion.com/maui/pdf-viewer/text-search#text-search-options

We don't have an advanced text search option in PdfViewer. However, we suggest that you can use the ExtractText API to obtain the phrases or lines and bounds information of the searched text. This will help you find the search text details in the document. To learn more about the details of the ExtractText, kindly refer to the below UG documentation link:

To display the phrases in a hierarchical structure as shown in the shared screenshot, you can use the SfTreeView package in Syncfusion. To learn more about the SfTreeView, kindly refer to the below UG documentation link:
