Hi Karthick,
Greetings from Syncfusion.
We have analyzed your requirement. You can achieve this requirement by using SfImageEditor control. We don’t have direct support to add the text on click position. So, we have prepared a workaround solution based on your requirement using the AddText method with Bounds property as a parameter. Please refer the sample from below location.
