Claim Text:
1. A method of decoding a texture data block that encodes a set of texture data elements to be used in a graphics processing system to determine the value of a texture data element that the texture data block represents, the method comprising: determining from the encoded texture data block, by processing circuitry, how to generate a set of data values to be used to generate data values for a set of the texture data elements that the block represents; determining from the encoded texture data block, by the processing circuitry, a set of integer values to be used to generate the set of data values to be used to generate data values for a set of the texture data elements that the block represents; generating by the processing circuitry the set of data values using the integer values; determining from the encoded texture data block, by the processing circuitry, the indexing scheme that has been used for the block; determining from the encoded texture data block, by the processing circuitry, an index value indicating how to use the generated set of data values to generate a data value for a texture data element of the set of texture data elements that the generated set of data values is to be used for, based on the determined indexing scheme; and using by the processing circuitry the index value and the generated set of data values to generate a data value for the texture data element.
