  • Publication number: 20240371058
    Abstract: This application discloses a scrolling screenshot method. When displaying a multi-column interface, an electronic device may receive an operation of triggering scrolling screenshot by a user. In response to the operation, the electronic device may simultaneously/sequentially take scrolling screenshots of a plurality of display areas, to obtain column-wise screenshot images of the display areas. The electronic device may compare lengths of the column-wise screenshot images to obtain a long column-wise screenshot image and a short column-wise screenshot image. The electronic device extends, with reference to a length of the long column-wise screenshot image, the short column-wise screenshot image by a length the same as that of the long column-wise screenshot image, and splices the short column-wise screenshot image and the long column-wise screenshot image together to obtain a long screenshot image. In this way, the long screenshot image with complete content can be obtained.
