How to delete text based on text orientation?


I would like to delete the text of a page based on text orientation.
Example : delete all text with 0 as angle and keep all others text angles.
The idea is to rasterize the page without the 0 angle text.

Is it possible ?

For now I just can delete all the text like in the sample :

OperatorSelector operatorSelector = new OperatorSelector(new AsposePdf.Operators.TextShowOperator());
                // Select all text on the page
                // Delete all text


Could you please share a sample PDF as well so that we can test the scenario in our environment and address it accordingly.

Here is a pdf, on page 8 there are rotated text over the image at the bottom ob the page Space_Threat_V14_020119_sm_46p.pdf (8.6 MB)

I want to remove all the text except the rotated one
