图片查看与画布Image viewing and canvas

图片第一次进入工作区：打开、显示、缩放、平移和适合窗口。Images entered the workspace with opening, display, zoom, pan and fit-to-window controls.

开发记录Development records 2026-10-06首次公开发布First public release 整理日期Prepared 2026-10-13

开发与阶段确认记录于 2026 年 10 月 6 日。Development and phase confirmation were recorded on 6 October 2026.

本阶段的变化What changed

  • 通过 Windows 原生选择器打开 JPG / JPEG / PNG，使用系统图像解码能力。Opened JPG / JPEG / PNG through the native Windows picker using system image decoding.
  • 显示 PNG 透明区域，建立滚轮缩放、拖动平移、Fit 和 100% 查看。Displayed PNG transparency and added wheel zoom, drag-to-pan, Fit and 100% viewing.
  • 原始素材按只读方式打开，载入后释放文件句柄。Opened original assets read-only and released file handles after loading.

验证与阶段结论Verification and outcome

  • 早期记录覆盖了基本打开、透明图片、选择取消、损坏文件提示、源文件解锁及正常关闭。Early checks covered basic opening, transparent images, picker cancellation, damaged-file feedback, source unlocking and normal shutdown.
  • Debug / Release 构建通过，本阶段已获得用户确认。Debug and Release builds passed, and the phase was confirmed by the project owner.

保留的边界Remaining limits

  • 大图显示有合理的资源边界；基础运行结果不代表所有尺寸与环境都已验证。Large-image viewing has resource limits; basic operation does not establish verification of every size and environment.

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.
