Printing equation division lines in pdf2txt text output #5

Mostly everything looks great, just fix the dynamic resizing of the equation line.
If possible, there seem to be some extra linebreaks in the output from reading an equation, could those linebreaks be removed? This can be seen in the example screenshot of the output as shown in this pullrequest. After the numenator of the first equation there is a linebreak before the Vinculum which cannot be seen in equation.pdf. Is that possible to fix?

The line length is fixed atm, but if an equation is very large, the line will not scale with its size.

Yes, this is because it is diffucult to know how long the line should be in the conosle. We do have access to how wide the line was in the pdf but converting that width into characters in the console is realy tricky and tedious. So for now it is like this
The line breaks could be removed but it's very tricky to do. The linebreaks comes from when pdfminer groups all elements into textboxes and there seems to be something going on there. But basically it is a challanging task that we leave as a future problem to solve |
We have done issue euske#305 where we have to display the division lines when outputting to the console.
