Calculus sample document (333.58 KB, application/pdf)

Calculus sample document

I was trying to convert PDFs for Calculus to HTML and have notices inconsistencies in the output. 

There is some whitespace before superscript text is printed. 
Also, in the attached file, there is some vertical text which is display horizontally in HTML.
There are other alignment issues for math, etc.

I have noticed similar issues with other documents containing calculus.

I am using version 0.16.4 of poppler with poppler-data 0.4.4 on a CentOS 5 box.

Please don't change Importance. That is a developer setting.

We do recognise that this bug is highly important to you, but this setting needs to reflect developer priorities.

Hey Brad,
      I understand that. Some sort of acknowledgement would have helped. Anyways, if someone can point me in the direction of the code or documentation, I can try and debug this myself.

I think response in < 48 hours is asking a lot from a volunteer project.

You can find information on the code linked off http://poppler.freedesktop.org/
If it looks OK in something that uses splash / cairo backends, then your issue is probably something missing in the HTML backend.

Good luck.

reviewed the html rendering but didn't find any issues there. probably something in the OCR part. 

any help there would be appreciated.

We don't do any OCR
