1. A decoder supporting wedgelet-based decoding of coding blocks, comprising:
a reader configured to read, using a processor one or more coded syntax elements from a data stream, the one or more syntax elements associated with a wedgelet separation line for a current coding block and indicating a direction, and an offset of the wedgelet separation line;
a wedgelet bi-partitioner configured to, using the processor, determine a bi-partitioning of the current coding block into two wedgelets in accordance with the wedgelet separation line obtained based on the one or more coded syntax elements, and associate each sample of the current coding block with one of the two wedgelets in accordance with a wedgelet pattern; and
a reconstructor configured to, using the processor, reconstruct the current coding block in accordance with the bi-partitioning.
