Hi, I installed ndless 3.6 and npdf . Got everything working and the pdf open, unfortunately it won't load past the first page or the cover sheet for that matter. I can zoom in and out on the cover sheet, but any page past the cover sheet is all white. It's as if there isn't enough ram or video processing power to load the next pages.

Any help would be great.

Thanks!

Hi.

nPDF isn't reliable, that's all. Personnally, I would never use it for an exam/test.

Online PDF conversion to Lua with its API 2.3+ is much more reliable :
editgx.php

Which calculator model are you using by the way ?

Thanks for the quick reply.

I have a nspire-cx CAS.

Ok, thanks. So it's not a memory problem then, it's just one of the many nPDF issues.

sorry to sound like a noob. Is there a diy guide to converting to tns? I found a website that converts pdf to TNS...clrhome.org/lua. Is there file size restrictions? my pdf is 609 pages long.

Thanks!

http://clrhome.org/lua doesn't deal with PDF files conversion at all.

Yes there are size restrictions, but the converters usually deal with them by splitting the document.

The PDF to tns converter is over there -> editgx.php - you can keep the default options and just submit your file.

I'm not sure it will successfully convert 609 pages with a free account.
But you can specify a subset of the document.
For example pages 1 to 100 for your 1st try, then 101 to 200 for your 2nd try, and so on.
It'll just increase the success chances.

Ok, got it. I reduced it to about 30 pages. Unfortunately there is an error with the file "An error was found in the format of this document."

Maybe it's not a PDF document, since you could apparently modify it.
Is there a possibility for you to share the file so we can check ?

Ok, so I used the converter but instead of lua I used Ndless. In the converter I chose Ndless then Npdf, in the converter I told which pages to choose. This was one file, then I did it again for the second half. I only need one chapter at this time so it was only 40 pages. Now it works

I'm not sure why the LUA conversion didn't work.

Thanks for the useful tips! It’s good to know that nPDF isn't very reliable and that converting PDFs to TNS using online tools like editgx.php is a better option. Also, breaking large PDFs into smaller sections seems to help avoid errors. Appreciate the insights
