Macro Scheduler 15

OCRArea

OCRArea>left,top,right,bottom,result

 

Not supported in Macro Scheduler Lite

 

Performs Optical Character Recognition against the specified screen region to retrieve text. Returns the recognised text in the result variable.

 

This function uses the Tesseract OCR engine via the included ocr.dll runtime file. Language files are stored by default in the "tessdata" folder in the main Macro Scheduler program folder. If compiling a macro that uses this function with Macro Scheduler Pro and selecting the option to copy runtime files the compiler will copy the ocr.dll and tessdata folder to the target folder. If you wish to point this function to a different folder that contains a tessdata folder, set the path with the OCR_LANGDIR variable.

 

To improve accuracy the image captured from the screen is scaled by a factor of 2. To set a different scale factor set OCR_SCALEFACTOR.

 

Note that OCR is processor intensive and therefore can take some time. The larger the screen region the longer it will take so it is best to try and keep the screen area small.
