Some way of retrieving a LepTess' image dimensions? #16

Closed kangalio closed 4 years ago

kangalio commented 4 years ago

Would it be possible to add a way to retrieve the dimensions of the image which is currently loaded in a LepTess instance?

We could add a helper method that uses GetInputImage API (https://github.com/tesseract-ocr/tesseract/blob/master/include/tesseract/baseapi.h#L139) to get a Pix object, then use it to return the dimension.

I had a go at implementing this. The Tesseract C++ library documentation was very hard to understand for me though, and I don't know if the code I wrote is sound.

Maybe you can be a better judge?
