python3 scripts/keyboard_mouse.py type_text "你好世界" --interval 0.05

Screenshot

# Save a screenshot (primary screen)
python3 scripts/keyboard_mouse.py screenshot /tmp/screenshot.png

# Windows example
python scripts/keyboard_mouse.py screenshot "E:\temp\screenshot.png"

Screenshot notes: - Supported formats: PNG (recommended), JPG, BMP, etc. - Scope: primary monitor (in multi-monitor setups)

Region Screenshot

# Screenshot specific region (x1, y1, x2, y2)
python3 scripts/keyboard_mouse.py screenshot_region region.png 100 100 500 500

# Windows example - capture QQ chat window area
python scripts/keyboard_mouse.py screenshot_region qq_window.png 2800 300 3800 1200

Parameters: - x1, y1: Top-left corner coordinates - x2, y2: Bottom-right corner coordinates - Order doesn't matter (automatically calculated)

Copy & Paste

# Copy text to clipboard
python3 scripts/keyboard_mouse.py copy "Text to copy"

# Paste from clipboard (Ctrl+V)
python3 scripts/keyboard_mouse.py paste

# Copy and paste in one command (fastest way to input text)
python3 scripts/keyboard_mouse.py copy_paste "Text to input directly"

Use cases: - copy_paste is faster than type_text for long text - Use copy_paste when you want to skip typing animation - Use type_text when you need to simulate realistic typing

Common key names

• Letters: a b c ...
• Numbers: 0 1 2 ...
• Function keys: f1 f2 ... f12
• Modifiers: ctrl alt shift win
• Others: enter esc tab space backspace delete up down left right

Safety

⚠️ Important: 1. Make sure the target window is focused before executing actions 2. Be careful with system hotkeys to avoid unintended actions 3. Add delays when needed to give yourself time to interrupt 4. Moving the mouse to the top-left corner (0, 0) triggers PyAutoGUI failsafe

Cross-platform notes

• Windows: Full support; admin permission may be needed in some environments
• Linux: Requires X11; Wayland may not work
• macOS: Grant Accessibility permission to Terminal/Python in System Settings

Screen overlay vs drawing on image

Item	Screen overlay (draw_overlay.py)	Draw on image (draw_on_image.py)
Display	Real-time on screen	Inside the image file
Duration	Temporary	Persistent
Interaction	Auto-close (time)	No interaction
Best for	Real-time coordinate validation	Generating annotated references
Output	Not saved	Saved to file

Recommended coordinate calibration (cost-saving)

python3 scripts/keyboard_mouse.py screenshot screen.png
python3 scripts/image_utils.py size screen.png

python3 scripts/draw_on_image.py screen.png marker target 3788 2080 --text "Candidate 1" -o marked1.png
python3 scripts/draw_on_image.py screen.png marker target 3790 2090 --text "Candidate 2" -o marked2.png

Image locating

Built on OpenCV template matching and RapidOCR. Supports locating UI elements by image and by text.

Install dependencies

pip install opencv-python numpy rapidocr_onnxruntime

Note: RapidOCR models are ~15MB and are downloaded automatically on first use.

Template matching (find by image)

python3 scripts/image_finder.py image button.png
python3 scripts/image_finder.py image button.png --all
python3 scripts/image_finder.py image button.png --threshold 0.95
python3 scripts/image_finder.py image button.png --mark
python3 scripts/image_finder.py image button.png --click

Output example:

✅ Match found: position (3788, 2080), similarity: 98.50%

OCR text locating (find by text)

python3 scripts/image_finder.py text "Send"
python3 scripts/image_finder.py text "OK" --click
python3 scripts/image_finder.py text "Send" --mark-on-image checked.png
python3 scripts/image_finder.py text-all
python3 scripts/image_finder.py text "Login" --confidence 0.9

Output example:

✅ Found 2 candidates containing 'Send':
  [1] Text: 'Send', position: (3788, 2080), confidence: 95%
  [2] Text: 'Send to all', position: (2100, 1500), confidence: 88%

Recommended automation workflows

Template matching (most accurate):

python3 scripts/image_finder.py image qq_send_button.png --threshold 0.9
python3 scripts/draw_on_image.py marker screen.png target 3788 2080 --text "Candidate 1" -o check1.png
python3 scripts/keyboard_mouse.py mouse_click_at 3788 2080 left

OCR text locating (when no template is available):

python3 scripts/image_finder.py text "Send"
python3 scripts/keyboard_mouse.py mouse_click_at 3548 1462 left

Important principle: 1. OCR returns accurate screen coordinates; do not modify the returned coordinates 2. If there are multiple candidates, mark them on an image to visually choose the correct one 3. Once you choose the right candidate, click using the original coordinates

Template matching vs OCR

Item	Template matching	OCR text locating
Accuracy	⭐⭐⭐⭐⭐ pixel-level	⭐⭐⭐⭐ depends on font/background
Speed	⭐⭐⭐⭐⭐ milliseconds	⭐⭐⭐ requires inference
Dependencies	OpenCV	RapidOCR
Best for	Icons/buttons/fixed UI	Text buttons/labels/inputs

Why this is better than guessing coordinates

1. High precision and repeatability (pixel-level)
2. Local compute with no API cost
3. Fast response
4. Easy to debug via marked outputs
