[tesseract-ocr] Re: Tess4J: Invalid memory access
setDatapath should be set to the path to tessdata folder, which contains
*.traineddata files. It's not the path to your image files.

Hi Quan,
I got the point. By the below video.
I miss download dependency.
https://www.youtube.com/watch?v=5DqW9KP-aQo=425s
And I will try that.
Thank you very much.

[tesseract-ocr] Re: Tess4J: Invalid memory access
Hi Quan,
'pth' is the image location in my PC.
I verified it with debug mood too.
As I know image location should set to the 'Datapath.'
If the 'pth' is incorrect what should pass for that parameter.
Realy helpful if you can further explain it to me, please ?

[tesseract-ocr] Re: Tess4J: Invalid memory access
I tested your sample image and confirmed the error. It looks like a bug in
the routine that determines the image's bit depth. A new version will be
released once a fix is worked out and committed.
Thank you for reporting.
