RE: [iText-questions] Characters shift up and down in edtiable multi-line textbox

[Alan Zhang]

I tried to use     

 

afFormFields.SetExtraMargin(10000,10000);

 

did not see any visual effects either on this problem, or any shift for other textboxes, either multi-line or single line one. Looks like it has absolutely no effects. I change the margin to 10, 100,1000,10000.

 

thanks
