Does anyone have solution to this? In the newer tesseract(4.x), the option textord_dump_table_images isn't available. I tried with tesseract 3.04, it works but creates an empty tess-table.txt file. I expected it to have co-ordinates of the detected file. Although when i use the option gapmap_debug=1 , it shows Table found , but i don't get to see the co-ordinates.
Any help??
