Abstract: An image decoder includes a processor and a memory. The memory includes instructions configured to cause the processor to perform steps. The steps include to receive a bitstream including a plurality encoded blocks representing an image, receive a boundary indicator representing a cropped portion of the image, determine a row start and a row end within the image based on the boundary indicator, and in a single decoding pass, entropy decode the plurality of encoded blocks that include the row start, the row end and the rows there between and transform for display a portion of the plurality of encoded blocks that include the rows including the cropped portion of the image, and skip processing of a remainder of the plurality of encoded blocks.
