I am able to process smaller files say up to 160 kb
When I hit 220 to 250 kb, I am having issues and getting the following
error:
Exception in thread "main" java.lang.Error: Invalid memory access

split_pt >0 && split_pt < word->chopped_word->NumBlobs():Error:Assert
failed:in file ..\..\ccmain\tfacepp.cpp, line 186
Using the following code
Tesseract instance = new Tesseract();
String result = instance.doOCR(outputFile );
Now if I set a rectangle in the doOCR I am able to process that rectangle
but not the complete image of course limited to the rectangle. I stepped
the rectangle around the file to determine if there is an issue and cannot
find a problem with the processing of the image, just a problem with
processing the entire image.
so if I process
new Rectangle(0, 0,1200, 1000) It works
If I exceed to new Rectangle(0, 0,1400, 1000), it fails with the above
error.
Is there some buffer size I need to adjust to allow for processing the
larger image or higher text content images?
Or is there a strategy I can employ other than making lots of rectangles :)
