The agtrip tool provides a quick and (relatively) easy way to convert screenshots or video capture of a scrolling arcade game into contiguous panoramas for later processing into playfields by agtcut.
The tool can rip backgrounds from vertical and horizontal scrolling captures. It can deal with variable scroll rates (including paused scroll) and is able to suppress/remove sprite content from the background - providing those sprites are in relatively continuous motion vs the background. Some options are also provided to help remove unwanted overlays such as text/hiscores and to help suppress sensitivity to parallax regions vs the primary scroll rate.
