Screenshot Capture

基于 mss + Pillow 的高性能屏幕截图工具,适用于 Windows 桌面自动化、AI 视觉分析等场景。

依赖

uv add mss pillow
# 或
pip install mss pillow

快速开始

作为 Python 模块使用

from scripts.screenshot import ScreenCapture

with ScreenCapture() as sc:
    # 获取屏幕分辨率
    width, height = sc.screen_size

    # 全屏截图 → PIL Image
    img = sc.capture()

    # 截图保存为文件
    sc.capture_to_file("output.png")

    # 截图转 base64 (用于发送给视觉 API)
    b64 = sc.capture_to_base64(quality=85, fmt="JPEG")

作为 CLI 工具使用

# 查看显示器信息
python scripts/screenshot.py info

# 截图保存到文件
python scripts/screenshot.py capture -o my_screenshot.png

# 截图输出 base64
python scripts/screenshot.py base64 --format JPEG --quality 85

核心 API

方法 说明 返回值
screen_size 主显示器 (宽, 高) tuple[int, int]
all_screen_size 虚拟全屏 (宽, 高),多屏合并 tuple[int, int]
monitors 所有显示器详细信息 list[dict]
capture(monitor, region, delay) 截图 → PIL Image Image.Image
capture_to_file(filepath, ...) 截图 → PNG/JPG 文件 Path
capture_to_base64(quality, fmt, ...) 截图 → base64 字符串 str

常见场景

发送截图给 OpenAI 视觉 API

from openai import OpenAI
from scripts.screenshot import ScreenCapture

client = OpenAI()
with ScreenCapture() as sc:
    b64 = sc.capture_to_base64(fmt="JPEG", quality=85)

resp = client.chat.completions.create(
    model="gpt-4o",
    messages=[{
        "role": "user",
        "content": [
            {"type": "text", "text": "描述截图内容"},
            {"type": "image_url", "image_url": {
                "url": f"data:image/jpeg;base64,{b64}",
                "detail": "high",
            }},
        ],
    }],
)

截取指定区域

with ScreenCapture() as sc:
    region = {"left": 100, "top": 200, "width": 800, "height": 600}
    img = sc.capture(region=region)
    img.save("region.png")

自动保存每步截图

with ScreenCapture(save_dir="screenshots") as sc:
    for i in range(5):
        sc.capture_to_base64(step=i)  # 自动保存为 screenshots/step_000.jpg 等
