이슈 추천
CPU Engine
-
Raster 성능 최적화 (Image Direct, Image Rotate…)
Infra
- workflow:
- Remove Redundant Build Tests: https://github.com/thorvg/thorvg/issues/4756
- unit test line coverage 측정 & 코드 리팩터링
- 커버리지 낮은 부분에 대한 테스트 코드 추가
- meson + lcov + genhtml
- 사용되지 않은 코드 정리
- 개선할만한 부분 이슈화
- 테스트 예시: https://github.com/thorvg/thorvg/pull/4814
- 커버리지 낮은 부분에 대한 테스트 코드 추가
Loader
- SVG compliance: https://github.com/thorvg/thorvg.svg-compliance
- 오픈소스 -> 보안 업데이트, 성능 개선, 버그 수정, 커스텀 등등 자율
- #4485 — webp: upgrade the webp decoder with the latest libwebp
- #2250 - jerryscript: replace the jerryscript memory allocator
- JS 인터프리터 JerryScript의 메모리 -> 메모리 System 으로 교체하는작업
- 바이너리 사이즈와 유연한 메모리 관리가 가능하도록 개선
- Lottie 의 Expression 기능 과 연관
IMPORTANT
- 성능 측정시 수정사항에 알맞는 방법으로
- thorvg.benchmark
- thorvg.example (Lottie, Animation …)
- 여러번 측정, Median, Mean 등 값으로 성능 측정치 PR 에 작성

Q & A
아래 내용은 개인적인 경험을 바탕으로 작성한 의견입니다.
- 특정 기업을 타겟팅하는 방법과 포트폴리오 주제 선정에 관해 질문드립니다.
- 채용 공고를 분석하고, 요구 역량과 연관된 주제를 선정하는 것이 가장 좋은 것 같습니다. (포트폴리오는 일관성 있게 구성)
- 채용 공고만으로 부족하다면, LinkedIn을 활용해 해당 기업에 재직 중이거나 이직·퇴직한 분께 커피챗을 신청해 이야기해 보는 것이 좋습니다.
- LinkedIn 프로필에는 자신의 성과, GitHub 주소, 포트폴리오, 이력서 등을 공개하는 경우가 많기 때문에 LinkedIn이나 GitHub를 탐색하는 것이 많은 도움이 됩니다.
- OSSCA와 같은 프로그램에 참여했다면, 해당 프로그램과 연관된 내용을 포트폴리오에 녹여내면 좋을 것 같습니다.
- 예: 실제 공고에 있는 단어와 실제 이슈를 연결한 기여 활동
- 수학·정교한 프로그래밍(1px 오차): Gradient AA 이슈
- PNG·JPG 등 파일 포맷: WebP Loader 버전 업데이트, PNG Saver
- 저수준 개발: 사용 중인 오픈소스 분석, ThorVG 자체 기여, SIMD, GPU Engine/CPU Engine
- 성능 최적화:
thorvg.example또는thorvg.benchmark프로파일링 후 개선 제안 및 PR - C++·JavaScript: SIMD와 WebSIMD
- 테스트: Unit Test와 Pixel Test에 기여
- 예: 실제 공고에 있는 단어와 실제 이슈를 연결한 기여 활동
