Here’s a way to get screen text from any application – even from an image – using OCR and a free open source tool called Tesseract.<\/p>\n
First, you need to download and install Tesseract. You can get it here<\/a>.<\/p>\n Tesseract is a command line utility. The most basic syntax is:<\/p>\n tesseract.exe input_image_file output_text_file<\/p><\/blockquote>\n So you could call it from a Macro Scheduler script something like this:<\/p>\n This example simply captures the entire screen. You probably wouldn’t normally want to do this. Instead you could capture a specific window:<\/p>\n Or even a specific object:<\/p>\n Either way you then have a screen bitmap you can pass into Tesseract.<\/p>\n Once you’ve retrieved the text you would probably want to parse it, using e.g. RegEx<\/a>.
