A compressed pixel block (400) is decompressed by defining multiple available property values. At least one reference point relative the pixel block (300) is identified based on a reference codeword (410) of the compressed pixel block (400). Pixel indices of the pixels (310) are determined based on the respective positions of pixels (310) in the pixel block (300) relative the at least one reference point. These pixel indices are used for selecting among the multiple defined property values. The selected property values are then assigned to pixels (310) to be decompressed based on their determined pixel indices.
