屏幕抓取应用程序（非 HTML）
I need screen scraper application which will recognize text from the screen (and not use winapi to do this so source could be in image file). I found a lot of commercial solutions, but I need something open source or free. I plan to include it in my C# project, so there should be some SDK available.Thanks.

您可以使用 Tessnet 对图像进行字符识别。如果您想屏幕抓取桌面，您可以只拍摄屏幕截图，将其转换为图像，然后使用上面的 OCR 库。
You could use Tessnet to do character recognition of your images. If you want to screen scrape the desktop, you could potentially just take a screen shot, turn it into an image, and use the OCR library above.
根据您想要执行的操作，我发现屏幕抓取工具对于对网站应用模式很有用并保存我关心的数据。教程页面应该让您了解它的作用。
Screen Scraper 的免费版允许使用解释型 Java、JScript、JavaScript、Python 和 VBScript 编写脚本。 ..足够接近了吗？
Depending on what you want to do, I have found screen scraper useful for applying patterns against a web site and saving the data that I care about. The tutorial page should give you an idea of what it does.
Screen Scraper's free edition allows scripting in Interpreted Java, JScript, JavaScript, Python, and VBScript... is that close enough?
