I have developed a bar-code reader application.
My problem is to display a line over the canvas where the video,
is played (view finder) and the image is to be captured.
I want the user to set the bar code on focus to the lines offset, so that the reading comes accurately(i.e. user can see the line and focus the required area over it which is the beginning of the Bar-code on the view finder ).
More Over I have seen the menu (Sony Ericsson's) default camera view finder, they have icons placed on the screen when you click on the settings.
Is it possible to achieve such thing.
and thanks in advance
