v0.4.2

SMLMRender v0.4.2

Diff since v0.4.1

v0.4.2 - 2026-03-10

Changes

• Add compose() utility for image layer compositing with blend modes
• Two blend modes: :additive (sum, clamp to [0,1]) and :replace (later non-black pixels overwrite)
• Decouples compositing from rendering — enables mixed-strategy overlays (e.g., Gaussian background + Circle overlay)
• Updated documentation: api_overview.md, docs/src/api.md, docs/src/examples.md

Breaking Changes

• None

v0.4.1

SMLMRender v0.4.1

Diff since v0.4.0

What's Changed

• Allocation-free colormap LUT with inline interpolation (replaces abstract ColorScheme dispatch)
• Fused clip+normalize+colormap single-pass operations in intensity color mapping
• Pre-sized non-zero buffers in clip_at_percentile (eliminates filter(vec(...)) allocations)
• Pre-built LUT hoisted out of per-emitter loops across all strategy renderers
• Type assertions to eliminate Union type instabilities in strategy accessor methods
• Removed accidental BenchmarkTools runtime dependency

• Release v0.4.1: Allocation-free rendering optimizations (#16) (@kalidke)

v0.4.0

SMLMRender v0.4.0

Diff since v0.3.1

v0.4.0

New Features

• ScaleBar.jl integration: scalebar, scalebar_length, scalebar_position, scalebar_color kwargs on all render() paths
• scalebar_length_um field in RenderInfo reports auto-calculated or explicit scalebar length
• Fix per-channel clip_percentile in overlay render path
• New dependency: ScaleBar v0.1

Breaking changes

• No breaking API changes. All new fields have defaults. Existing code works unchanged. Minor version bump for new dependency and struct fields.

• Release v0.4.0: ScaleBar integration and overlay clip_percentile fix (#14) (@kalidke)

v0.3.1

SMLMRender v0.3.1

Diff since v0.3.0

v0.3.1

Bug Fixes

• Fix histogram RGB overflow: field, categorical, and manual renders produced RGB values >1.0 in dense pixels
• Fix manual histogram dynamic range: replace max_count normalization with percentile clipping

Enhancements

• Widen RenderConfig.clip_percentile to Union{Float64, Nothing} — pass nothing for saturate mode (no normalization, classic overlay behavior)
• Wire clip_percentile through render_overlay() and render(smlds::Vector; ...) for end-to-end control (defaults to nothing for overlays)

v0.3.0

SMLMRender v0.3.0

Diff since v0.2.0

Breaking changes

• CircleRender/EllipseRender default radius_factor changed from 2.0 to 1.0
• Field-based Gaussian brightness uses linear clip+normalize instead of gamma correction

New features

• Wire clip_percentile from RenderConfig through field/categorical Gaussian rendering
• Re-export SMLMData via Reexport.jl
• Add rendering gallery to docs

Other changes

• Rewrite README with conceptual overview, Config-first API, Unicode field names
• Replace SMLMSim-based doc examples with self-contained Siemens star test pattern
• Convert all doc examples to (img, info) tuple pattern with RenderConfig

Merged pull requests:

• Release v0.3.0: Rewrite docs, wire clip_percentile, re-export SMLMData (#11) (@kalidke)

v0.2.0

SMLMRender v0.2.0

Diff since v0.1.0

Breaking changes

• render() now returns (image, info) tuple instead of bare image or RenderResult2D
• New RenderConfig <: AbstractSMLMConfig replaces kwargs-only interface: render(smld, config::RenderConfig)
• RenderConfig has 14 flat fields (strategy, pixel_size, zoom, roi, colormap, etc.)
• kwargs form render(smld; kwargs...) still works, kwargs match RenderConfig fields exactly
• RenderInfo <: AbstractSMLMInfo provides timing, backend, emitter counts, output metadata
• Requires SMLMData 0.7.0 (AbstractSMLMConfig/AbstractSMLMInfo)

Other changes

• Ellipse rendering support (from feature/ellipse-render branch)
• All Config/Info types inherit from SMLMData abstract types

Merged pull requests:

• Add EllipseRender, absolute_frame coloring, and docs (#8) (@kalidke)
• Add tuple-pattern API with RenderInfo struct (#10) (@kalidke)

v0.1.0

SMLMRender v0.1.0

SMLMRender.jl v0.1.0 - Initial Release

Initial public release of SMLMRender.jl, a Julia package for rendering single-molecule localization microscopy (SMLM) data into publication-quality images.

Core Features

Three Rendering Strategies:

• HistogramRender: Fast binned histograms with field-based color mapping
• GaussianRender: Smooth blob rendering weighted by localization precision

Advanced Color Mapping:

• Intensity-based color mapping with customizable colormaps
• Field-based color mapping (z-depth, photon count, frame number, precision)
• Intensity-weighted field colors for enhanced visualization
• Colorbar export for publication figures

Multi-Channel Support:

• Render multiple channels as overlays
• Automatic color assignment or custom colors per channel

Documentation:

• Complete Documenter.jl documentation with executable examples
