1. An image decoding method performed by an image decoding apparatus, the image decoding method comprising:
acquiring size information indicating a size of a current slice corresponding to at least a portion of a current picture from a bitstream; and
determining the size of the current slice based on the size information,
wherein the size information includes width information indicating a width of the current slice in units of tile columns and height information indicating a height of the current slice in units of tile rows, and
wherein the acquiring the size information is performed based on whether the current slice belongs to a last tile column or a last tile row of the current picture,
wherein the height information of the current slice is not acquired from the bitstream based on a top left tile of the current slice belonging to the last tile row of the current picture.
