Windows11 SnippingTool OCR

blog post: https://b1tg.github.io/post/win11-oneocr/

Tested on Win11 23H2 + SnippingTool 11.2409.25.0

Build this code needs opencv installed.

How to use:

The code depends on the DLLs and offline AI model, the easiest way is copy those files from SnippingTool folder, puts them in the same folder of ocr.exe

includes:

• oneocr.dll
• oneocr.onemodel
• onnxruntime.dll

On my computer the SnippingTool folder located at C:\Program Files\WindowsApps\Microsoft.ScreenSketch_11.2409.25.0_x64__8wekyb3d8bbwe\SnippingTool (You may need to change the access rights in the Security Tab of the properties (add your user as the owner))

Install OpenCV (4.6.0)

also add the opencv_world460.dll

Install VS with MSVC / C++ packages. Use x64 Native Tools Command Prompt for VS 20XX to build the app for x64 systems.

The build scripts now use /EHsc for C++ exception handling and will look for OpenCV in either:

• the OPENCV_DIR environment variable, or
• common install locations such as C:\Tools\OpenCV_4_6\build

Make sure the OpenCV 4.6.0 headers and opencv_world460.lib are available before building.
