Hi,
what does page.AddContent(content, true); return?

If it returns true I think you have some problems with the position so with the matrix..
If it returns false there are some problems with the others parameters you are using.
Remember that to use these methods you need a premium license..

Hi Davide ,
page.AddContent(content, true) always return true as i can see output at screen .but its not pointed to correct location at pdf

Thanks for modified code .i pass the parameter of touch points in your code .this touch coordinates work fine with edit box.

PageContent content = new PageContent();
content.Create();//create content, do not forget.
content.GSSave();
Matrix mat = new Matrix( 1, 1, x, y);
content.GSSetMatrix(mat);
mat.Destroy();

Please help
