A VS Code extension that opens a webview where you can load or paste an image, drag a crop rectangle, and run OCR on the cropped area using OCR.space.
Features:
Load image via file picker, drag-and-drop, or paste from clipboard
Drag to crop visually on a canvas
Run OCR and see text, confidence, and duration; copy the result
Instant OCR runs automatically as soon as you finish drawing a crop and whenever you adjust the Threshold or Scale sliders (debounced).
Preprocessing (upscaling + grayscale threshold) happens locally in the webview before sending the image to the OCR API.
If the output is wrong, adjust the Threshold and Scale sliders; OCR re-runs instantly and cleaner binarization usually improves accuracy.
Configuration:
Settings → “CAPTCHA OCR Cropper”:
captchaOcr.ocrSpaceApiKey: OCR.space API key (default helloworld demo key)
captchaOcr.language: OCR language code (default eng)
captchaOcr.engine: Engine 1 or 2 (default 2)
Usage:
Command Palette → “CAPTCHA OCR: Open Cropper”
Load/paste an image, draw a crop, click “Run OCR”
Adjust the threshold and scale sliders until the characters are cleanly black-and-white; the extension will re-run OCR instantly.
Notes:
Replace the demo key with your own for production use.
If you need offline OCR, we can switch to a bundled Tesseract.js worker. If you meant a Visual Studio (Windows) VSIX instead of VS Code, tell me and I’ll generate that template.
