0.3.0

Highlights

bluetape4k-image 0.3.0 adds OCR and large-file image I/O capabilities, then aligns the image stack with the bluetape4k-dependencies 1.3.x train. The release focuses on practical adoption paths: basic OCR, Spring Boot OCR, Ktor OCR, and memory-conscious streaming image workloads.
Related: #170 #174 #181 #182 #168 #167

OCR support

• Added OCR module support with runnable quickstart examples for basic OCR usage.
• Added a Spring Boot OCR example for users who want auto-configuration-style adoption.
• Added a native-free Ktor OCR quickstart and kept the Ktor example away from snapshot-only core wiring.
• Made OCR runtime gating portable across native ABI drift so CI can validate the path without depending on one host-native layout.

Large image I/O and benchmarks

• Added memory-conscious large-file image I/O APIs backed by Okio.
• Expanded large-image and streaming benchmark coverage so performance discussions are tied to measured workloads.
• Kept benchmark harness code under the benchmark workspace instead of leaking benchmark concerns into production modules.
  Related: #168 #167 #209

Runtime and release alignment

• Refreshed image golden-chain Nightly coverage and stabilized scheduled snapshot dependency resolution.
• Aligned the release line with bluetape4k-bom 1.11.0, bluetape4k-aws-bom 0.4.0, and the stable dependencies catalog.
• Reduced compileTestKotlin warning noise and refreshed shared catalog references for common/OpenTelemetry aliases.

Documentation and diagrams

• Rebuilt README and example diagrams for root overview, class responsibilities, OCR architecture, example routing, and native-host boundaries.
• Enriched the root README overview and made diagrams readable at rendered size rather than only in source form.

Full Changelog: 0.2.0...0.3.0

0.2.0

Added

• images-captcha module for CAPTCHA image challenge generation, refreshable challenge services, and verification service contracts (PR #88, PR #119, PR #127, closes #4, #101).
• images-ktor route helpers for CAPTCHA issue/verification and multipart thumbnail APIs, aligned with shared bluetape4k-ktor-* helpers (PR #119, PR #127, PR #136, closes #118, #135).
• Runnable examples for pure JVM processing, Spring Boot local storage, and Ktor image APIs (PR #128, PR #130, PR #131, closes #124, #125, #126).
• Research-backed image AI dependency strategy for OCR, face/object detection, and classification follow-up work (PR #129, closes #83, #84, #85).

Changed

• Prepared the release line to consume io.github.bluetape4k:bluetape4k-bom:1.10.0 and the public stable io.github.bluetape4k.aws:bluetape4k-aws-bom:0.3.0 (PR #92, PR #94, PR #134).
• Refreshed vips/java21/java25 benchmark evidence, natural-photo fixtures, charts, and benchmark report regeneration guidance (PR #89, PR #117, PR #121, PR #122, closes #86, #103, #104, #105).
• Documented AVIF/HEIC native codec boundaries, libvips runtime setup, CAPTCHA lifecycle ownership, and completed 0.2.0 roadmap state (PR #87, PR #120, PR #95, closes #111, #112, #113, #114).

Removed

• Removed the ImmutableImage.useGraphics(...) and hammingDistance(...) compatibility shims that were deprecated for removal in 0.2.0; use ImmutableImage.withGraphics { } and HashDistance.hamming(a, b) instead (#61).

Fixed

• Hardened optional S3/CDN auto-configuration fallback behavior and release workflow catalog selection (PR #97, PR #119, closes #109).
• Guarded native vips lifecycle and FFM arena cleanup contracts, including AVIF/HEIC capability-gated read/write support, double-close, use-after-close, codec capability, and failed creation paths (PR #115, PR #116, closes #100, #107, #108).
• Restricted workflow token permissions for repository automation (PR #132).

Full Changelog: 0.1.1...0.1.2

0.1.1

Added

• images-spring-boot module: Spring Boot 4 auto-configuration for image storage, CDN signing, reactive health, and Micrometer metrics. Includes LocalImageStorage, S3ImageStorage, S3PreSignedUrlSigner, CloudFrontUrlSigner, and five auto-configuration phases (PR #42, closes #5).
• Root README hero image plus refreshed project-purpose and feature entrypoint documentation (PR #27).
• bluetape4k-image-bom BOM module for image library consumers (PR #12).
• English and Korean README files for the image BOM module (PR #13).
• GitHub Actions workflows for CI, nightly, snapshot, release, and code-quality checks (PR #7).

Changed

• Extended test coverage for images module: batch processing, animated writers, filter DSL, and utility functions (PR #41).
• Added unit tests for VipsImage writer classes in images-vips-java21 and images-vips-java25 (PR #40).
• Added FfmVipsRuntime concurrency test for images-vips-java25 (PR #39).
• Prepared the 0.1.1 release line to consume io.github.bluetape4k:bluetape4k-bom:1.9.0 and io.github.bluetape4k.aws:bluetape4k-aws-bom:0.2.0.
• Split Nightly into smoke/full lanes and normalized lessons, Kover, Dependabot, NMCP, and compatibility-guard maintenance (PR #15, PR #16, PR #17, PR #18, PR #22, PR #24, PR #25, PR #26).
• Updated image dependency catalog and related dependency bumps, including JVips and annotations (PR #14, PR #20, PR #21, PR #23).
• CI uses path filtering and retry configuration (PR #10).
• Test code migrated from Kluent to bluetape4k-assertions (PR #11).

Removed

• Pre-stabilization typo compatibility APIs from images: usingSuspend(...), SuspendPngWriter.NoComppression, and the misspelled ImageOuptputStreamSupportKt Java facade. ImmutableImage.useGraphics(...) and hammingDistance(...) remain deprecated until removal in 0.2.0 (#61).

Fixed

• Aligned POM license metadata from Apache 2.0 to MIT across all published modules (PR #38).
• Aligned repository license text as MIT across all modules (PR #28).
