I am a trial user,
How to select a region(area) by the mouse,
And fill it with white?

Hello

First, you have to set the viewer MouseMode property to MouseModeAreaSelection : https://www.gdpicture.com/guides/gdpicture/web ... eMode.html.
After that, users can draw a selection area.
You can get the coordinates with this method :https://www.gdpicture.com/guides/gdpicture/web ... ument.html
And fill with a rectangle with this method :https://www.gdpicture.com/guides/gdpicture/GdP ... an%29.html
