B4J Question PDF Document Generation - Getting XY Position

Hi there

For those creating and updating PDF documents. I need some help. I need a PDF tool that I can use that will tell me the exact location of where my mouse pointer is on a PDF page, so that I can write at that location using code.

For example, I open the PDF document. I find a spot, then i click on it, it tells me that XY is 150x100 for example.

Then I can use that 150x100 point on my code to update the PDF document.

Thanks
