Abstract: A processor-implemented method includes: determining whether a plurality of tile sets of different zoom levels comprises a tile image, based on either one or both of a position of the tile image in a virtual image and a size of the tile image, wherein tile image corresponds to a visible region covered by a preview interface in the virtual image; updating the tile image based on whether the plurality of tile sets comprises the tile image; and generating a preview image corresponding to the tile image by stitching the updated tile image.
