Nebula 1.8.0 是一次图片大版本。核心是一套用 Rust 加速的云端图片浏览器 / 编辑器:重活(解码 / 缩放 / 编码 / EXIF)全放到后端、按 ETag 磁盘缓存,前端只拿摆正缩好的小图,大图也秒开;编辑器在独立窗口里提供裁剪 / 拉直 / 调整尺寸 / 旋转 / 翻转 / 灰度 / 反相与亮度 / 对比度 / 饱和度 / 色温 / 锐化 / 模糊 / 色相全套调整,配撤销重做、实时预览,可选 JPEG / PNG / WebP 格式与画质,一键存回云端或下载到本地。标注侧有画笔 / 矩形 / 箭头 / 文字(可描边)/ 序号标记 / 吸管取色与笔刷式马赛克。最亮眼的是可下载的本地 AI 去背景插件——启用后下载模型与运行时,全程在本机推理、不上传任何图片,覆盖 Windows / macOS / Linux 的 x64 与 arm64;再配上魔术棒(点一下去掉相连的相似区域)与橡皮擦(涂抹精修)两个局部擦除工具。此外还带来批量重命名、命令面板直接执行动作,以及日文界面。

Nebula 1.8.0 is an imaging release. At its core is a Rust-accelerated cloud image viewer / editor: the heavy work (decode / resize / encode / EXIF) runs in the backend and is disk-cached by ETag, so the webview only ever handles a small, upright image — even huge originals open instantly. The editor, in its own window, offers crop / straighten / resize / rotate / flip / grayscale / invert and brightness / contrast / saturation / warmth / sharpen / blur / hue, with undo/redo, a live preview, a choice of JPEG / PNG / WebP and quality, and saving back to the cloud or downloading locally. Annotation adds pen / rectangle / arrow / text (with outline) / numbered markers / eyedropper and a brush-style mosaic. The highlight is a downloadable on-device AI background-removal plugin — enable it to fetch the model and runtime, then everything runs locally with nothing uploaded, across Windows / macOS / Linux on both x64 and arm64 — paired with two local erase tools: a magic wand (click to remove a connected similar-colour area) and an eraser (paint to refine). It also brings batch rename, running actions straight from the command palette, and a Japanese UI.

版本信息 | Release Information

Rust 加速的图片浏览器 | Rust-accelerated Image Viewer

  • 重活放后端:解码 / 缩放 / 编码 / EXIF 全在 Rust 侧完成,并按 ETag 磁盘缓存原图与各变体;前端只拿「已摆正、已缩到视口大小」的小图,一张几十 MB 的原图也能秒开。
  • 独立窗口浏览:每张图在自己的窗口打开,支持缩放 / 平移 / 旋转 / EXIF 信息(含 GPS 一键看地图);网格缩略图同样走后端管线,不再为每张图拉整张原图。

Decoding, resizing, encoding and EXIF all happen in Rust, with originals and variants disk-cached by ETag, so the webview only ever receives a small, already-upright image — even a 40 MB original opens instantly. Each image opens in its own window with zoom / pan / rotate and EXIF (including one-tap GPS on a map); grid thumbnails use the same backend pipeline instead of fetching full originals.

功能完整的图片编辑器 | A Full Image Editor

  • 几何与色彩:裁剪、任意角度拉直、调整尺寸、旋转、水平 / 垂直翻转、灰度、反相,以及亮度 / 对比度 / 饱和度 / 色温 / 锐化 / 模糊 / 色相的滑块调整。
  • 撤销重做与保存:每步可撤销 / 重做,实时预览(在缓存的缩图基底上出图,响应快);可选 JPEG / PNG / WebP 格式与画质,覆盖原图 / 另存为新对象 / 下载到本地任选。

Crop, arbitrary-angle straighten, resize, rotate, horizontal / vertical flip, grayscale, invert, plus brightness / contrast / saturation / warmth / sharpen / blur / hue sliders. Every step is undoable / redoable with a fast live preview rendered on a cached downscaled base; pick JPEG / PNG / WebP and quality, then overwrite the original, save as a new object, or download locally.

标注与打码 | Annotate & Redact

  • 标注工具:画笔、矩形、箭头、文字(可加描边提升可读性)、序号标记(1 → 2 → 3 自动编号)、吸管取色;文字浮层跟随缩放 / 平移,保存时用系统字体合成(支持中文)。
  • 马赛克打码:像画笔一样在图上涂抹打码,遮盖敏感区域。

Pen, rectangle, arrow, text (with an optional outline for readability), numbered markers (auto 1 → 2 → 3) and an eyedropper; the text overlay follows zoom / pan and is composited with system fonts on save (CJK supported). Mosaic works like a brush you paint over the regions to redact.

AI 去背景与局部擦除 | AI Background Removal & Local Erase

  • 可下载的 AI 去背景插件:默认安装包不含 AI 运行时;在设置里启用后下载模型(u2netp)与 ONNX Runtime(带进度条),重启生效。全程在本机推理,不上传任何图片;覆盖 Windows / macOS / Linux 的 x64 与 arm64,不支持的平台会明确提示。
  • 魔术棒 / 橡皮擦:两个纯本地、免模型的局部擦除工具——魔术棒点一下去掉与该点颜色相近且相连的一整片(可调容差),橡皮擦按住涂抹精修边角;都在全分辨率上操作、可撤销,结果作为透明 PNG 存回。

The default installer ships no AI runtime; enable the plugin in Settings to download the model (u2netp) and ONNX Runtime with a progress bar, then restart. Inference runs entirely on-device — nothing is uploaded — across Windows / macOS / Linux on x64 and arm64, with a clear notice on unsupported platforms. Two model-free local tools complement it: a magic wand that clicks away a connected similar-colour region (adjustable tolerance) and an eraser you paint to refine edges; both work at full resolution, support undo, and save back as a transparent PNG.

效率与国际化 | Productivity & i18n

  • 批量重命名:多选对象后按规则批量改名(加前缀 / 后缀 / 查找替换),先预览后执行。
  • 命令面板执行动作:Cmd/Ctrl+K 命令面板除了跳转,还能直接执行刷新 / 上传 / 新建等动作。
  • 日文界面:界面新增日文,语言由注册表驱动、便于继续扩展。

Multi-select objects and batch-rename them by rule (add prefix / suffix / find & replace), previewed before applying. The Cmd/Ctrl+K palette can now run actions (refresh / upload / new folder …) directly, not just navigate. The UI adds Japanese, with locales driven by a registry that makes further languages easy.

签名与传输修复 | Signature & Transfer Fixes

  • 签名更严谨:阿里云 OSS 的 CanonicalizedResource 用原始 key、华为 OBS 用百分号编码后的 key(遵循 S3 V2),两者不再混用,修复了含中文 / 空格文件名的上传失败;空 body 的 PUT(如新建文件夹)显式带上 Content-Length,修复 MissingContentLength。

OSS signs the raw object key in its CanonicalizedResource while OBS signs the percent-encoded key (per S3 V2) — no longer conflated, fixing uploads of names with CJK / spaces. Empty-body PUTs (e.g. creating a folder) now send an explicit Content-Length, fixing MissingContentLength.
