TixTab 0.3.6

TixTab 0.3.6 — 展示全屏与原生语音 / Presentation and native speech

中文

下载 TixTab-0.3.6-lite-setup-x64.exe。Windows 11 x64，支持升级已有安装并保留工作空间、设置和已下载模型。安装包未签名，可使用随附 SHA256SUMS.txt 校验。

• 展示全屏：三种视图可隐藏其它界面并居中展示，保留缩放和五线谱自动翻页；双击退出并恢复编辑视图。单页/双页支持触屏与触控板双指左右滑动翻页，惯性尾段不会连续翻过多页。放大后左右滑动用于平移，连续视图保留滚动。
• Windows 原生语音：新增可选 Windows AI Speech 本地实验后端与 Windows SDK Speech 后端，显示实际麦克风音量波形。修复首次系统模型加载过早超时、持续听写阻塞结果读取/停止的问题，增加启动阶段与进度提示。停止听写关闭本次采集和识别，模型按设置的空闲时间保留并卸载，修改设置会同步更新计时。
• Surface Pen 尾键助手：设置中可选择启用，仅在 TixTab 前台接管；单击打开助手并开始/结束听写，双击结束听写并发送，发送前收取最后一句。识别失败时保留文字，不自动发送。
• 后台进度：下载和文档处理可收起并继续执行，由小型浮窗查看进度、重新打开或取消；任务结果归属原文档，避免切换后写入其它文档。
• 界面与文本：未编辑的空白文档不加入工作空间，分组选择按钮避免图标重叠；悬浮键盘收到实体键盘输入后隐藏；修复 Markdown 删除线。

轻量包不包含神经模型权重。Windows AI Speech 仍为实验接口，需要兼容的系统、硬件、应用组件身份与系统模型，模型由 Windows 管理，可能需要通过 Windows Update 下载；SDK Speech 可能联网。首次 NPU 编译在本机实测约 6 分 40 秒，缓存后的加载约 7 秒，此数据仅代表本机测试，不是跨设备性能承诺。尾键依赖设备向应用提供对应快捷键事件，自动化输入不替代实体笔验收。

本轮完成原生语音加载、停止、真实音量计和模型驻留的本机检查，以及自动化回归、安装包静态校验；未运行本机安装器或打包后的 Electron。保留此前 Hy-MT2 OpenVINO NPU 初始化失败的限制，不宣称该翻译后端已支持本机 NPU。

English

Download TixTab-0.3.6-lite-setup-x64.exe for Windows 11 x64. Upgrades retain workspaces, settings and downloaded models. The installer is unsigned; verify SHA256SUMS.txt.

• Presentation fullscreen for all three layouts, centered fitting, zoom, score auto-turning, double-click exit and editor-view restoration. Touchscreen and horizontal trackpad gestures turn single pages/spreads once per gesture; magnified pages retain panning and continuous mode retains scrolling.
• Optional experimental local Windows AI Speech and Windows SDK Speech, with real microphone level meters. Fix cold-start timeouts and blocking continuous-recognition startup, report load stages/progress, and keep idle models for the configured unload interval while ending each capture session.
• Opt-in foreground Surface Pen tail assistant: single-click starts/stops dictation; double-click stops and sends after draining the final phrase. Recognition failures retain text without automatic sending.
• Background downloads/processing with a compact progress dock and document-owned results. Hide the floating keyboard on physical input, omit untouched blank workspace documents, improve grouping controls and fix Markdown strikethrough.

Neural weights download separately. Windows AI Speech requires compatible Windows/hardware, component identity and system models; first compilation may take minutes. SDK Speech may use online services. Local smoke measurements do not establish cross-device performance or physical pen acceptance. Installer and packaged Electron execution were not rerun. The earlier local Hy-MT2 OpenVINO NPU initialization limitation remains.

TixTab 0.3.5 — PDF object editing & translation

TixTab 0.3.5 — PDF 对象编辑与翻译 / PDF object editing and translation

中文

下载 TixTab-0.3.5-lite-setup-x64.exe，可升级已有 Windows 11 x64 安装，并保留工作空间、设置与已下载模型。程序未签名，请核对随附 SHA256SUMS.txt。

• PDF 对象编辑：合并 claude/pdf-object-audit，使用 PDFium 编辑原生文字、图片和路径对象的位置、大小、旋转、翻转及叠放顺序；支持多选、对齐、分布、键盘微调、填充/描边和线宽。拖动预览显示实际对象，每次操作可撤销。文字内容修改和图片替换保留原有编辑入口，并修复部分原生文字拒绝编辑的问题。对象操作当前直接应用并重新保存文档，超大文档可能较慢；尚不支持完整的 Foxit 功能集。
• 便签与草稿纸：便签工具创建后自动切换到移动工具并选中新便签；关闭按钮收起对应便签，再次点击锚点可打开。修复草稿纸便签定位、文本输入和草稿截图 OCR。橡皮擦及笔尾橡皮可在一次拖动中跨 PDF/草稿纸工作，两侧实时预览，一次撤销恢复；松手、取消或退出草稿模式释放预览缓冲。
• 原图查看器：下载按钮左侧新增复制；左右两侧的触屏按钮与键盘方向键浏览前后图片，按文档页序跨页并跳过无图页。切图重置缩放，复制与下载保留原图像素和颜色，关闭时取消加载并释放画布。
• 快捷面板与笔触：右下角改为更多操作图标，包含删除页、清空本页标注、复制页、插入空白页和翻译入口。笔触悬浮预览改为实际落笔半径圆圈；顶部标签与底部工具条隐藏滚动条，保留滚动操作。
• 常驻翻译与 Hy-MT2：无需先划词即可打开并编辑翻译内容；目标语言旁提供三个最近使用的语言快捷项。新增可选本地 Hy-MT2 1.8B，以及 llama.cpp CPU/Vulkan 和 OpenVINO 后端，复用已有运行环境与模型管理；修复桌面端这两个后端设置的保存校验。

Hy-MT2 权重和运行组件按需下载，不捆绑在轻量安装包中。OpenVINO CPU/GPU 已有本机推理验证，但初始化可能较慢；本机 NPU 初始化未成功，不宣称 NPU 可用或加速。系统模型、硬件与真实文档仍需自行验收。此次未在本机运行安装器或打包后的 Electron，也不把模拟输入作为实体 Surface Pen 验收。

感谢 Anthropic Claude 对 PDF 对象编辑实现与审计的贡献；已加入中英文 README 的贡献者名单，与项目维护者及 OpenAI Codex 一同署名。

• Merge Claude's PDF object editing work: selection, live move/resize/rotate previews, flips, stacking, alignment/distribution, keyboard nudging and fill/stroke controls. Operations are undoable; text content and image replacement retain the existing editor. Object operations currently apply directly and re-save the document; large files may be slow.
• Fix review-note editing/placement, scratch capture and cross-sheet erasing, including pen-tail input, previews, undo/cancel and buffer release.
• Copy original images beside Download; browse with side touch buttons or Left/Right keys across document pages, skipping pages without images. Native pixels/colors are preserved, zoom resets on image changes and closing releases resources.
• Add page quick actions, brush-radius previews, standalone editable translation and three recent target-language shortcuts. Hide overflow scrollbars while retaining scrolling.
• Optional Hy-MT2 1.8B translation via llama.cpp CPU/Vulkan or OpenVINO, sharing existing runtime/model management. Fix desktop persistence of both new provider profiles. Weights download separately; OpenVINO CPU/GPU inference was checked locally, while local NPU initialization failed and is not claimed to work.

Thanks to Claude by Anthropic, credited as an AI coding contributor for PDF object editing implementation and auditing alongside the project maintainer and OpenAI Codex. Installer and packaged Electron execution were not rerun on this host; automated/synthetic checks do not replace hardware acceptance.

TixTab 0.3.4 — PDFium, scratch paper & local tools

TixTab 0.3.4 — PDFium、草稿纸与本地文档工具 / PDFium, scratch paper and local tools

中文

下载 TixTab-0.3.4-lite-setup-x64.exe，可升级已有安装并保留工作空间、设置和已下载模型。Windows 11 x64；程序未签名，请核对随附 SHA256SUMS.txt。

• PDFium WASM 完全替代 PDF.js：本地引擎常驻复用，关闭文档释放句柄；迁移页面渲染、缩略图、文字/链接/目录、表单显示、图片索引及提取。修复整页扫描图缩放黑屏、阅读位置回到页顶、竖排文字区域和 PDF 元素暂存预览问题。人工验收见 PDFium 检查清单。
• 草稿纸：最多十张独立背景，分开平移缩放，与原 PDF 跨边界书写；可从缩略图拖入独立页面快照、调整图层、隐藏原 PDF、修改背景。草稿与视图状态随工作空间保存，草稿不进入 PDF 导出。页面快照禁止复制/剪切，普通对象可跨两层复制粘贴。改善连续页面衔接、边缘阴影和夜间显示。
• 工作空间：文档拖入分组，卡片保存第一页预览，旧档缺少预览时留空；连续批注组显示文件份数与进度，首次打开下一份继承视图模式。标签支持定位原文件所在文件夹，紧凑布局修复遮挡和左侧控制位置。
• 文本与图片：Markdown/纯文本切换和夜间预览；图片透明色取样与 RGB 容差；四边独立拉伸、四角等比缩放、顺/逆时针旋转 90°、矩形裁剪与原图恢复。修复裁剪后再拉伸仅选框变化的问题，三种视图、缩略图、截图和 PDF 导出保持一致。
• 文档矫正：本地扫描倾斜纠正与 UVDoc 透视/曲面矫正，支持当前页、全文、指定页和指定图片；先预览再应用。UVDoc 复用现有 OpenVINO 环境，可选 CPU/GPU/NPU，不兼容时说明原因或回退。逐张处理，子进程结束后释放模型。
• 乐谱工具：默认 Audiveris，可选 homr，识别结果附在页面并保存到工程。浮动播放器默认钢琴，可选择合成音色；BPM 刻度滑条支持滚轮每格 1、Shift+滚轮每格 5，范围 20–400。支持点击谱面定位、自动翻页、音符 MIDI 音高/时值修正和 MIDI 导出。
• homr 播放定位：符号坐标换算回原页，并吸附到附近检测音符头；通过 MusicXML note ID 保留和弦/声部重排后的对应关系。竖线停在当前起拍音符，跨行延音保留后续位置。旧 homr 结果请重新识别。少数 attention 估计位置仍可能有偏差。
• OCR 与手写：可选原生 C++ Tesseract CPU 后端；Windows AI OCR 组件入口与身份注册诊断；位图索引避免提前解码全文。改进小尺度轨迹采样、粗笔触轮廓、高倍率实时笔迹、独立笔宽记忆和带压感的橡皮预览。Alt 键鼠交互与笔侧键框选保持一致。

轻量包不含可下载神经模型或 Audiveris/homr 组件。首次使用相应功能需下载本地组件；homr 因 Python 版本要求使用兼容的按需环境。声音输入翻页为单旋律音高跟随实验，不能保证复调演奏准确对齐。Windows AI OCR 取决于 Windows 版本、NPU、系统模型与应用身份；NPU OCR 原型仍有精度/设备限制，未宣称比 WASM 更快，C++ NPU 原型未捆绑。合成音色不是外部 SoundFont 加载器。

升级不自动写回原 PDF。草稿和可编辑信息保存在工作空间/工程；导出结果请用另一查看器核对。构建通过自动测试与安装包静态校验，本机未执行安装器或成品 Electron，不把模拟输入当作 Surface Pen 硬件验收。

Download TixTab-0.3.4-lite-setup-x64.exe and verify SHA256SUMS.txt. Supports upgrading existing Windows 11 x64 installations while retaining workspaces, settings and downloaded models. Unsigned executable.

• PDFium WASM replaces PDF.js completely, including rendering, thumbnails, text/navigation, form display and bitmap extraction. Fixes scan-page zoom transitions, reading-position restoration, rotated text regions and staged PDF-edit previews.
• Independent scratch papers, detached page snapshots, separate pan/zoom, cross-boundary handwriting, saved per-tab state and night rendering. Scratch content stays in projects and is excluded from PDF export.
• Workspace drag-to-group, persisted first-page previews, sequential-review group metadata, view-mode inheritance and compact-header fixes.
• Markdown text boxes with night previews; image color keys, independent edge stretching, proportional corner resizing, 90° rotation and reversible cropping. Cropped images now stretch correctly in all three layouts and PDF export.
• Local deskew and UVDoc document correction, with preview/apply, selected bitmap and page ranges. UVDoc reuses the OpenVINO environment and offers CPU/GPU/NPU where compatible.
• Audiveris/homr score recognition, page-attached results, local synthesized instruments, draggable BPM control with wheel adjustment, score seeking, automatic page turns, note correction and MIDI export.
• homr cursor locations now use symbol geometry and MusicXML note identities, including chord reordering and tied continuations. Re-recognize existing homr results to obtain new positions. Attention-only locations may still be approximate.
• Native C++ Tesseract CPU option, Windows AI OCR component diagnostics, bitmap-index memory improvements and pen sampling/rendering/eraser refinements.

Optional models and Audiveris/homr components download separately. homr uses a compatible on-demand Python environment. Microphone following is an experimental monophonic pitch matcher. Windows AI OCR depends on compatible Windows, hardware, models and identity registration. Experimental NPU recognition retains accuracy/device limitations; no speed advantage over WASM is claimed, and the C++ NPU prototype is not bundled. Instruments use local synthesis, not external SoundFont loading.

Original PDFs are not overwritten automatically. Verify exports in another viewer. Automated tests and static package checks do not replace installer, actual pen-hardware or real-document acceptance.

TixTab 0.3.3 — Clipboard & sequential review

TixTab 0.3.3 — 剪贴板与连续批注 / Clipboard and sequential review

中文

下载 TixTab-0.3.3-lite-setup-x64.exe，运行安装器可升级已有安装，保留工作空间、设置与模型。Windows 11 x64，支持 Surface Pen。程序未代码签名，请核对随附 SHA256SUMS.txt。

• 新增带预览的会话剪贴板历史：文本、图片、可编辑草图/公式/文本框及笔迹，点击直接粘贴。普通模式数据预算 128 MiB，极低内存模式 32 MiB，不限制条数，超额淘汰最旧项；预览分页、载荷按需读取。可暂停、删除和清空，历史不保存到磁盘，不导入先前 Windows Win+V 内容。
• 修复 Alt 框选笔迹后的复制/剪切操作条被 PDF 拦截点击；增加复制成功提示与异步防重复提交。撤销、恢复和剪贴板入口移至工具栏最左侧，折叠时也保留。
• 左侧页面多选：键盘 Shift+方向键扩选、回车/空格切换，鼠标与触屏拖选。多选时导航改为全选/全不选/反选；退出恢复。支持跨文档整批复制粘贴，保留页面尺寸、可编辑笔迹、对象、便签和 OCR 信息，整批可撤销；长文档保留缩略图虚拟化。
• 工作空间新增文件夹连续批注：递归索引 PDF，默认打开第一份，所有文件归入一个标签。按需读取文件并保存各自编辑进度；浮窗支持上一份/下一份、序号跳转、文件名搜索，以及逐份导出已编辑 PDF。浮窗缩至 270 CSS px，可拖出 PDF 区域；导出可取消，不覆盖原文件或已有同名输出。
• 应用改为单实例，再次启动聚焦已有窗口；移除 Alt 触发的默认桌面菜单，保留应用内快捷键与框选操作。

连续批注目前每份源 PDF 上限 256 MiB、每个文件夹索引最多 10,000 份 PDF；切换文件保留已保存批注，撤销历史在文件切换时重置。原始 PDF 不会被自动写回，批量导出选择单独目录，子目录文件名会展平并处理重名。独立 .tixtab 工程只包含当前文件，不包含整个文件夹。剪贴板记录可能含敏感文本或图片，请按需暂停/清空；预算约束的是记录数据，不是整个应用进程的内存上限。

轻量包不含神经模型权重，按需在本地模型管理下载。此前实验性 NPU/中英混合 OCR、设备兼容性与识别精度限制不变。本轮通过单元测试、浏览器交互回归和安装包静态检查；未在本机再次执行安装器或打包后的应用。

Download TixTab-0.3.3-lite-setup-x64.exe and verify SHA256SUMS.txt. The installer upgrades existing installations while preserving workspaces, settings and models. Windows 11 x64; supports Surface Pen. Unsigned executable.

• Preview and paste session clipboard history for text, images, editable sketches/formulas/text boxes and ink. 128 MiB data budget, 32 MiB in minimal-memory mode, with no item-count limit and oldest-entry eviction. Paged previews and on-demand payloads; pause, delete and clear controls. History is not persisted or imported from previous Windows Win+V entries.
• Fixed ink Copy/Cut toolbar clicks intercepted by the PDF surface after Alt selection, with copy confirmation and duplicate-operation guards. Undo, Redo and clipboard controls are at the left, including collapsed layouts.
• Multi-page sidebar selection with Shift+arrows, Enter/Space and mouse/touch dragging; select all/none/invert replaces normal navigation while selecting. Copy/paste multiple pages across documents as one undoable batch, retaining dimensions, editable foreground content, review notes and OCR metadata. Long lists remain virtualized.
• Sequential folder review keeps all PDFs in one tab, indexes recursively and reads files on demand. Individual edits and reading positions are retained. A 270 CSS px floating navigator moves across the application window, with previous/next, numeric jump, filename search and sequential export of edited PDFs. Export supports cancellation and never overwrites originals or existing outputs.
• Single application instance: reopening focuses the existing window. Alt no longer opens the default desktop menu; in-app shortcuts and ink selection remain available.

Folder review currently limits each source PDF to 256 MiB and each folder index to 10,000 PDFs. Switching files preserves saved edits and resets per-file undo history. Originals are not written back automatically. Export uses a chosen output folder, flattening subdirectory filenames and resolving collisions. A standalone .tixtab project contains the current file, not the entire folder. Clipboard records may contain sensitive information; pause or clear them as needed. Its budget measures stored history data, not total application memory.

The lite build excludes neural model weights; download them as needed. Existing experimental NPU/mixed OCR accuracy and device compatibility limitations remain. Unit tests, browser interaction regressions and static package checks were completed; the installer and packaged application were not rerun on this host.

TixTab 0.3.2 — OCR、资源与编辑改进

TixTab 0.3.2 — OCR、资源与编辑改进 / OCR, resources and editing

中文

下载 TixTab-0.3.2-lite-setup-x64.exe，运行安装器可升级已有安装，保留工作空间、设置和模型。Windows 11 x64，支持 Surface Pen。程序未代码签名，请核对随附 SHA256SUMS.txt。

• “解析位图”增加独立的 Tesseract · NPU · 实验性 后端，可选英文 Best/Fast 或 简体中文 + English · 混合 Best。使用有界 16 行队列；英文最大 batch 1/2/4，混合模式暂固定单行推理。CPU 负责分行及前后处理，NPU 失败明确报错，不静默 CPU 回退。
• 加固 CPU OCR 停止：取消加载/解码/清理等待，专用扫描 PDF worker 立即退出；保留已完成结果。4 路任务另受 400 万活动输入像素总预算限制，大图减少并发并共享空闲 worker，回收闲置高水位工作区，避免轮流撑大四套 WASM 堆。
• 增加“耗时详情”，查看分行、推理、本次编译和服务处理时间。累计任务时间可能重叠，不等同整批实际耗时；NPU 不保证更快或更省电。
• 截图和原图可保存 PNG；聊天按钮旁的额外工具支持提取当前页、全文或指定页的位图，保存到所选目录。逐张处理、可取消、避免覆盖已有文件。
• 支持跨文档复制/粘贴页面，保留可编辑笔迹、对象、便签和 OCR 元数据；单页源快照、剪贴板及撤销源历史有内存上限。
• 设置增加整体界面倍率 0.5–4.0（现有大小以 2.0 为基准），以及默认线性的分段压感曲线。可添加最多 16 个内部点，拖动、删除及恢复默认；只影响 PDF、公式和草图中的新笔迹。

轻量包不含神经模型权重。NPU 后端需在“本地模型管理”准备本地加速运行时、分行语言包及所选识别模型；混合 Best 单独下载约 12.5 MiB，更新后重启应用/本地服务。混合模式已验证中英合成样本，仍可能漏空格或识别错误；未完成文档级人工精度评测。原 CPU Tesseract 仍为默认。详见 OCR 说明。

Download TixTab-0.3.2-lite-setup-x64.exe and verify SHA256SUMS.txt. The installer upgrades existing installations while preserving workspaces, settings and models. Windows 11 x64; supports Surface Pen. Unsigned executable.

• Optional experimental queued Tesseract NPU backend for bitmap analysis: English Best/Fast and mixed Simplified Chinese/English Best. A bounded 16-line queue; English maximum batches 1/2/4, mixed mode currently single-line inference. CPU handles layout and pre/postprocessing. NPU errors are explicit, without silent CPU recognition fallback.
• Hardened CPU OCR cancellation and dedicated scan-worker teardown, keeping completed results. A 4-million-active-input-pixel budget reduces concurrency for large scans. Idle OCR owners are shared and oversized idle working sets retired instead of growing four separate WASM heaps across decode lanes.
• Timing details for layout, inference, compilation and service processing. Task times may overlap and are not batch wall time. NPU speedups or battery savings are not guaranteed.
• Save captures/original images as PNG; Extra tools can extract bitmap images from the current document to a selected folder, with page ranges, cancellation, sequential resource release and no overwrite.
• Cross-document page copy/paste preserves editable foreground content, review notes and OCR metadata, with bounded page snapshots, clipboard and source undo history.
• Overall UI scale 0.5–4.0, with 2.0 matching the existing size; a piecewise pressure curve with up to 16 internal control points. New PDF/formula/sketch strokes use the curve; existing strokes stay unchanged.

The lite build excludes neural weights. Prepare the local acceleration runtime, layout language pack and selected OCR model in the model library; mixed Best is a separate approximately 12.5 MiB download. Restart the updated application/local service. Mixed synthetic samples were validated, but spacing errors remain and document-level accuracy is not established. The CPU Tesseract default is unchanged. Installation itself was not rerun on this host.

TixTab 0.3.0 is the first usability and interaction milestone for a touch/pen PDF workspace. Supports Surface Pen.

Download the lite x64 installer and verify SHA256SUMS.txt. Choose an installation directory, upgrade/repair an existing installation, and optionally add a desktop shortcut. Core PDF features need no separate runtime; optional AI models and managed Python are downloaded in-app.

Highlights: consistent collapsible UI and themes; editable ink/objects in all views; pen-hover interaction highlights and side-button/Alt ink selection; document search/outline/bookmarks and direct page jumps; bitmap OCR indexing with page ranges and line highlights; nested object groups; persistent formula drafts and incremental LaTeX insertion; multi-page/image chat attachments and a detachable assistant.

Rendering optimizations retain image quality, separate background/foreground work, share bounded text caches and retire old rasters. Model/compilation reuse and configurable idle unloading remain enabled. Resource measurements are not battery-life guarantees.

Windows 11 x64, unsigned. Recognition, night colors and account chat remain experimental. Check recognized content; keep editable .tixtab projects alongside PDF exports. Bitmap OCR metadata is searchable in TixTab projects, not embedded in exported PDFs. Optional weights require downloads and their own licenses. Remote providers receive submitted content and control their usage limits. Other hardware, ARM64, complex forms/encrypted/signed documents and PDF annotation interoperability have limitations.

AGPL-3.0-only application code; third-party components/models retain their own licenses. Corresponding source: v0.3.0.

TixTab 0.2.38 · Compact keyboard shortcuts

TixTab 0.2.38 · 键盘快捷键与划词定位 / Keyboard shortcuts and selection placement

中文

• 悬浮键盘更紧凑，直接在按键布局中加入 Ctrl、Tab、Esc。先点 Ctrl 再点 A/X/C/V/Z/Y 可全选、剪切、复制、粘贴、撤销或重做，执行后自动松开 Ctrl。输入框保留焦点及选区，键盘输入支持原生撤销；PDF 页面的复制/粘贴继续使用已有的文本、图片和对象剪贴板流程。独立聊天窗口也支持这些快捷键。
• 划词浮窗优先比较选区上下方的可用空间；按实际 PDF 视口计算，避开悬浮键盘和底部工具组。空间不足时缩短面板并允许滚动，保留惯用手方向的水平对齐。

运行 TixTab-0.2.38-lite-x64.exe。Windows x64 未签名预览版；可选运行时和模型按需下载。本次不改动模型和推理设备设置。

English

• Make the keyboard more compact and integrate Ctrl, Tab and Esc into its key rows. Tap Ctrl then A/X/C/V/Z/Y for select all, cut, copy, paste, undo or redo; Ctrl releases after the action. Preserve field focus and selection, record native undo history, and reuse the PDF text/image/object clipboard workflow. Shortcuts also work in the independent chat window.
• Prefer the roomier region above or below selected text, using the actual PDF viewport and excluding the floating keyboard and bottom control groups. Shorten and scroll the panel when space is limited, retaining writing-hand alignment.

Run TixTab-0.2.38-lite-x64.exe. Unsigned Windows x64 preview; optional runtimes and models download on demand. Model and inference-device settings are unchanged.

TixTab 0.2.37 — Speech loading and render recovery

TixTab 0.2.37 · 语音加载与渲染恢复 / Speech loading and render recovery

中文

• 修复 Whisper NPU 编译缓存反复被清理的问题：本机完整缓存约 850 MiB，超过原 768 MiB 目标；调整为 2 GiB，继续复用既有缓存。独立进程复测模型加载约 4 秒，之前重复加载约 44–51 秒。时间不含 Python 启动、校验和麦克风初始化，不代表所有设备。
• 常驻语音模型直接复用，避免每次扫描全部模型。取消已加载的录音后停止采集、丢弃待返回文字，排空后保留模型；加载期间取消仍终止进程。默认闲置卸载时间保持 1800 秒。
• 修复丢失触摸/笔松手事件导致全部 PDF 页面持续等待的问题；停止输入后自动恢复，持续书写时继续让出渲染资源。
• 修复初始窗口可见性查询晚到而覆盖恢复事件的问题。卡住的页面加载/绘制加入超时保护，取消可立即释放队列，避免阻塞其它文档。

运行 TixTab-0.2.37-lite-x64.exe。Windows x64 未签名预览版；模型和运行时按需下载。首次缺少缓存、清理缓存或更新驱动/运行时后仍可能编译。本次没有测量功耗、续航或真实笔延迟。

English

• Fix repeated Whisper NPU compilation caused by pruning required cache blobs. The measured working set is about 850 MiB, exceeding the previous 768 MiB target; the target is now 2 GiB and existing caches are retained. Fresh-process model loading measured about 4 seconds versus 44–51 seconds before, excluding Python startup, verification and microphone initialization.
• Reuse resident speech workers without scanning every installed model. Cancelling a loaded recording stops capture, discards pending text, and retains the model after draining; cancelling during loading still terminates the worker. Idle unloading remains 1800 seconds by default.
• Recover PDF rendering after missing touch/pen release events, while continuing to defer work during active handwriting.
• Ignore stale initial visibility snapshots after newer window events. Bound stalled render stages and release cancelled queue slots immediately so other documents can continue.

Run TixTab-0.2.37-lite-x64.exe. Unsigned Windows x64 preview; optional models/runtimes download on demand. Missing/cleared caches and driver/runtime updates can still require compilation. No new power, battery-life or physical-pen latency measurements are claimed.
