Member Function Documentation

◆ allocData()

bool grk::CompressCodeblock::allocData ( size_t nominalBlockSize )

inline

Allocates data memory for an compressing code block.

We actually allocate 2 more bytes than specified, and then offset data by +2. This is done so that we can safely initialize the MQ coder pointer to data-1, without risk of accessing uninitialized memory.
