raster-d v0.5.3

raster-d v0.5.3 release notes

raster-d v0.5.3 extends bounded, synchronous data-plane execution to
multiple independently backed source views. It remains generic: RGB, mask,
histogram and colour semantics belong to consumers such as imagery-d.

Public API

• withViewsParallelPhases for source-only multi-view analysis;
• withViewsIntoParallelPhases for multi-view analysis followed by a
  destination transform;
• independent view and plane validation with common logical extents;
• callback-scoped grouped affine windows with the existing bounded phase
  barriers, stable worker indices and alias checks.

The source-view collection is homogeneous by sample type. This keeps the
public callback strongly typed and allocation-free while supporting RGB data
plus a separately backed byte mask.

Qualification

• DMD and LDC unit tests pass, including DIP1000 probes;
• all PR #272 release gates pass;
• the release benchmark covers the imagery-shaped RGB plus separate-mask
  workload with worker-local 65,536-bin histograms and deterministic
  reduction before the three-channel float transform.

v0.5.2

What's Changed

• Release raster-d v0.5.2 by @alex-1974 in #271

raster-d v0.5.1

raster-d v0.5.1 release notes

raster-d v0.5.1 adds a generic, opt-in parallel row-kernel primitive to the
callback-scoped data-plane API. It is independent of imagery-d and does not
install a process-wide scheduler.

Public API

• parallelRows
• ParallelRowsResult
• withPlanesIntoParallel

The callback receives callback-scoped source/destination windows and a
half-open logical row range. It must be @safe nothrow, write only its assigned
rows, and must not retain borrowed arguments. All workers are joined before
return. Failed callbacks may leave partial destination writes.

Qualification

• DMD and LDC unit tests pass.
• LDC ThreadSanitizer unit tests pass.
• Tests cover negative row strides, ROI geometry, alias rejection, callback
  failure, sequential fallback and multi-worker coverage.
• The release benchmark covers 1024×768 and 1920×1080 with multiple worker
  limits and chunk sizes.

Persistent worker reuse, queueing, cancellation and affinity remain caller
responsibilities and are not part of raster-d's public scheduler contract.

v0.5.0

Highlights

• Added public callback-scoped strided row access for planar and interleaved kernels.
• Exposed validated row data and sample stride through RasterPlaneRow and WritableRasterPlaneRow.
• DMD RGB benchmark improved from 3.78 ns/pixel to 1.79 ns/pixel with no material LDC regression.
• Added release notes and external-consumer benchmark evidence.
