基础编辑与导出闭环Basic editing and export

形成打开图片、编辑、撤销重做和导出新文件的基础流程。Completed a basic workflow from opening and editing through undo, redo and export to a new file.

有条件接受Conditionally accepted
开发记录Development records 2026-10-06 · 2026-10-08首次公开发布First public release 整理日期Prepared 2026-10-13

阶段开始有 10 月 6 日记录；实际 GUI 与补测报告日期为 10 月 8 日。The phase began in records dated 6 October; GUI and follow-up test reports are dated 8 October.

本阶段的变化What changed

  • 加入矩形裁剪、裁剪框调整与移动、图片尺寸调整及比例控制。Added rectangular cropping, crop handles and movement, image resizing and aspect-ratio controls.
  • 加入亮度、对比度、饱和度预览，以及明确的确认和取消。Added brightness, contrast and saturation previews with explicit confirm and cancel actions.
  • 支持 PNG / JPEG 导出，保持原始素材保护，导出后仍可继续编辑。Added PNG / JPEG export while protecting original assets and allowing editing to continue afterwards.

验证与阶段结论Verification and outcome

  • 实际界面测试覆盖基础编辑闭环；受控素材的源哈希、透明度采样及 JPEG 白底检查有记录。GUI tests cover the basic editing workflow, with recorded source hashes, alpha samples and JPEG white-background checks on controlled assets.
  • 本阶段有条件接受，测试结论仅适用于报告明确覆盖的范围。The phase was conditionally accepted; results apply only to the scope explicitly covered by the reports.

保留的边界Remaining limits

  • 大图切换后的内存保留尚需调查，不能据有限趋势认定已修复或不存在泄漏。Memory retained after large-image switching requires further investigation; limited trends do not establish a fix or the absence of a leak.
  • 预览与导出存在采样和处理差异；部分极端失败路径仍未全面验证。Preview and export have sampling and processing differences; some extreme failure paths remain incompletely verified.

本篇记录阶段当时的成果与验证范围。后续修复和新增能力另行记录，不能把旧候选结果继承给新版本。This entry records the phase outcome and verification scope at that point. Later fixes and capabilities are recorded separately; prior results do not establish a new candidate as passed.

项目与归档说明Project and archive notes

免费、本地优先、无账号的 Windows 多媒体处理与编辑软件。当前开发重心是图片工作区。A free, local-first Windows multimedia processing and editing application without accounts. Current development focuses on the image workspace.

铁柱 Studio 在建立公开开发日志体系之前，已开展多个阶段的开发。自 2026 年 10 月 13 日起，项目开始建立通过 untitled24 归档开发历程的体系。此前日志根据已有工程记录、开发文档和测试报告整理补录，持续记录开发过程、版本演进和项目成果。历史开发日期与实际日志发布日期分别保留。Tiezhu Studio had already progressed through several development phases before this public log was established. From 13 October 2026, the project began establishing its development archive through untitled24. Earlier entries are reconstructed from existing engineering records, development documents and test reports to preserve the process, version evolution and results over time. Historical development dates and actual publication dates are recorded separately.

这里公开阶段成果、验证摘要与必要的已知限制。内部实现、开发环境、源码和原始证据仅用于本地事实核对。This archive shares phase outcomes, verification summaries and necessary known limits. Internal implementation, development environment, source code and raw evidence remain local for fact-checking.
