Detailed Description

Per-image pool of per-thread scratch buffers for the 5/3 wavelet.

Replaces the former static pool in WaveletReverse so that multiple images can decompress concurrently without sharing scratch memory.

Member Function Documentation

alloc()

bool grk::WaveletPoolData::alloc

(

size_t

maxDim

)

Allocate per-thread horiz/vert scratch buffers.

If already allocated with sufficient size, this is a no-op.

Parameters

maxDim

maximum image dimension (width or height)

Returns

true on success
