1. A method of decoding an image, the method comprising:
obtaining maximum transform skip size information from a bitstream;
obtaining transform skip information of a current block from a bitstream on the basis of the maximum transform skip size information;
obtaining multiple transform selection information of the current block on the basis of the transform skip information from the bitstream; and
performing inverse transform on the current block on the basis of the multiple transform selection information,
wherein the multiple transform selection information is used to set each of a horizontal transform type and a vertical transform type,
wherein the transform skip information is used for both a luma component and a chroma component, and
wherein the multiple transform selection information is used only for the luma component.
