Constructor & Destructor Documentation

◆ CodeblockCompress() [1/2]

grk::t1::CodeblockCompress::CodeblockCompress ( uint16_t numLayers )

inlineexplicit

Constructs a CodeblockCompress This struct is a wrapper for CodeblockCompressImpl, where the implementation lies.

Parameters

numlayers Number of layers in code block

Member Function Documentation

◆ allocData()

bool grk::t1::CodeblockCompress::allocData ( size_t nominalBlockSize )

inline

Allocates data memory for a compression 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.

Parameters

nominalBlockSize nominal block size - actual size may be smaller
