wotool

简体中文

A tray-resident OCR / translation tool for Windows, built with WinUI 3.

The project started as a WPF app (rewritten from NPCDW/WindowsFormsOCR), in branch 'wpf', and has now been ported to WinUI 3 (Windows App SDK) with a shared platform-agnostic core library.

It calls cloud platform open APIs for text recognition and translation, and currently only supports the platforms listed below.

Build

Requires .NET 8 SDK and Windows 10 1809+ (Windows App SDK 1.6).

dotnet build wotool.sln -c Release -p:Platform=x64

Upgrade

Configuration file storage path:

• User directory (default), you can directly delete the old version of the program folder, and then decompress and replace it with the new version of the program
• Before replacing an older release, preserve its Config/Setting.json, then restore that file in the new program folder.

The configuration schema is unchanged; a new Common.theme key is added (defaults to Default = follow system).
