Python - OS X 中的屏幕抓取和控制鼠标

我正在研究 OS X 中的屏幕抓取和控制鼠标的爱好项目。

我并不是在寻找最优雅的方式，但我需要能够每半秒左右捕获一次屏幕。

我发现我可以使用 screencapture 命令行工具 (screencapture -w -W -i ~/Desktop/capture.jpg)，但我很担心它可能不够快。

我也在寻找一种发送点击、设置光标位置和获取光标位置的方法。有点像 win32api 提供的：mouse_event、SetCursorPos 和 GetCursorPos。

我发现这个示例代码使用 PyObjC 库来设置光标位置，但它总是将我的鼠标移动到 (0,0) 而不是我传递给它的坐标。

import objc

class ETMouse():   
    def setMousePosition(self, x, y):
        bndl = objc.loadBundle('CoreGraphics', globals(),
                '/System/Library/Frameworks/ApplicationServices.framework')
        objc.loadBundleFunctions(bndl, globals(),
                [('CGWarpMouseCursorPosition', 'v{CGPoint=ff}')])
        CGWarpMouseCursorPosition((x, y))

if __name__ == "__main__":
    et = ETMouse()
    et.setMousePosition(500, 500)

编辑：如果重要的话，我正在运行 Snow Leopard (10.6)。

谢谢！

I'm looking into screen-scraping and controlling the mouse in OS X for a hobby project.

I'm not looking for the most elegant way, but I need to be able to capture the screen every half a second or so.

I've found that I could use the screencapture command-line tool (screencapture -w -W -i ~/Desktop/capture.jpg), but I'm worried that it might not be fast enough.

I'm also looking for a way to send clicks, set the cursor position and obtain the cursor position. Sort of like what win32api provides: mouse_event, SetCursorPos and GetCursorPos.

I've found this sample code that uses the PyObjC library to set the cursor position, but it's always moving my mouse to (0,0) instead of the coordinates I pass it.

import objc

class ETMouse():   
    def setMousePosition(self, x, y):
        bndl = objc.loadBundle('CoreGraphics', globals(),
                '/System/Library/Frameworks/ApplicationServices.framework')
        objc.loadBundleFunctions(bndl, globals(),
                [('CGWarpMouseCursorPosition', 'v{CGPoint=ff}')])
        CGWarpMouseCursorPosition((x, y))

if __name__ == "__main__":
    et = ETMouse()
    et.setMousePosition(500, 500)

Edit: I'm running Snow Leopard (10.6) if it matters.

Thanks!
