File openhtj2k.changes of Package openhtj2k
-------------------------------------------------------------------
Tue Mar 31 07:14:43 UTC 2026 - Michael Vetter <mvetter@suse.com>
- Update to 0.4.1:
* Introduce a temporary workaround for the line-based validation test in
Windows ARM64.
-------------------------------------------------------------------
Tue Mar 31 07:13:23 UTC 2026 - Michael Vetter <mvetter@suse.com>
- Update to 0.4.0:
New APIs:
* Add invoke_line_based() decoder API: row-by-row output via callback
using per-subband ring buffers; avoids full-image intermediate allocation
* Add invoke_line_based_stream() decoder API: multi-tile scatter path
assembling full-width output rows from per-tile strip buffers
* Add encode_line_based_stream() encoder API: push-row streaming encoder
driven by a user-supplied source callback
* Add lb_compare utility to validate line-based output against invoke()
Architecture:
* Change sprec_t from int32_t to float: DWT pipeline now operates
natively in float32, eliminating integer↔float round-trip conversions
* fdwt_2d_state / idwt_2d_state: new stateful streaming DWT classes
that process one row at a time for the line-based encode/decode paths
* Line-based mode is now the default for encoder and decoder apps;
the previous full-image (batch) path is selected with the -batch flag
Performance:
* AVX2 horizontal DWT: 2× loop unrolling on all lifting step loops
* NEON: full float32 horizontal and vertical DWT kernels
* ICT/RCT color transforms: AVX2 and NEON variants with runtime dispatch
* LB decoder: pipeline MCT+clamp of row Y with pool pull of row Y+1,
achieving 18–23 % throughput improvement at T≥4 threads
* Encoder: per-thread cblk_data_pool bump allocator replaces per-block
malloc/free in the HTCOT hot path; PSE scratch buffer hoisted out
of per-tile DWT calls
Build / Tests:
* Decoder and encoder apps reject unknown command-line flag names
* Introduce OPENHTJ2K_EXPORT macro, removing duplicated __declspec
guards from encoder.hpp
* Add lb_stream_validation.cmake: conformance tests for
invoke_line_based_stream() across all HT profile-0/1 and HF bitstreams
* Remove redundant lb_* cmake test files (duplicate of non-lb equivalents);
* CTest count reduced from 480 to 277
* WASM: dark UI redesign, SIMD badge, decode-time display, GitHub link
