I use calibre, an ebook manager which lets you perform this through the GUI, as well as through a script called ebook-convert.
Sorry, I don't know when I will get the time to implement it. Also, it would be good advice not to rely on a calculator for the exam. ;)

Don't misunderstand my words : I don't rely on the calculator for the exam, I hate who pass in such way.
I'm studying night and day both verbal and training parts, my only thought is that it's always better owning a weapon that can turn out to be useful if necessary than haven't because formulas are (too) much, just it (maybe I wouldn't have written that words) ;)
Standing at your words implementing search and scrolling would have been easy, but I'll wait noiselessly, you'll have done yet a great work updating the library to 1.8 version (I hope pdf rendering would be improved by this update) :)

Sorry, I was caught up with school work. I have uploaded nPDF 0.4 beta. Since you requested it, a build is included that supports EPUB and HTML. :)

Also, you don't need to use the PRG file on OS 3.6. The ndless_resources.tns file from Ndless 3.9 that has Zehn support actually works on 3.1 and 3.6. Just replace your ndless_resources.tns with the one from 3.9, nPDF.tns should run. Unfortunately, this isn't well-documented.

You can still use the PRG file, even if your ndless_resources supports Zehn. It will detect that automatically and load the Zehn part of the file directly.

I'm using successfully the PRG file :D

With nspire overclocked performances are radically improved : @234Mhz opening a document, zooming and scrolling is become fast and smooth, against stock frequency of 132Mhz I used before on Ndless 3.9
The new version seems great : as you revealed into post #72 searching and the 3 scrolling modes will be the tidbits, but before rendering a file I was accountable myself as an option that show the current page number and if possible also than of first and last page would give more importance to 'go to page' function that uses CTRL+G because could help us finding a whole part inside the document from what we remembered of it.
Do you think could be easy to implement? :)

Yes, I know. Still, the Ndless 3.1 and 3.6 archives should be updated.

I could add the first and last page shortcuts right now. Any suggestions for what they should be?

I think we could call the shortcuts respectively 'prologue' and 'epilogue' using a literary key :)
But I mean also show the number of current page riproduce to help the user surfing the PDF's tree!

Or even better, point to the same file, containing the current release with all installers.

OK, but what do you think the actual keyboard shortcut should be?

That would also work, of course :)

I couldn't have replied before because from some days Tapatalk doesn't let me logging in also if username and password are correct (I have also just changed password, but always the same).
About the disposition, I'll think on to give you my advice :)
But recently I have betrayed the same problem described into issue #14 on your Github https://github.com/Legimet/nPDF/issues/14 : also if the PDF I've opened is compressed to maximum using an online service (ilovepdf) after nearly 30 pages the screen became suddenly white.
I think it runs out of memory, do you know how could be fixed this setback?
I believe would be useful including into the program a script to free RAM memory after the exit, because when I had showed this glitch then my calculator has started to lag becoming sluggish.

Agreed @ the White Screen Issues.  I tried to reproduce it after a reboot by loading a 14mb pdf and several 3mb pdfs and scrolling through fifteen pages of each but I could not.   I got bored at that point. Does nPDF only queue the next page?  I am not familiar with pdfs as a file structure.  When it happened a week ago I had not rebooted for a month so i do not know what remnant may have been lingering. 

An another note, just found out that those with Ndless 3.9 are not able to reboot their gonkulators w/o a 5v powered micro usb.  Is that in low power or hight power mode?  like a wall wart or a computer?  That sucks!

@shaunny, I will take a look at the issue.

Thats probably because of a new security mod suronome made for the website. I have heard some other sites also had talptalk problems with soru's mod ;)

Also lol i know this is like two years old, but a pdf viewer on calc is cool! I wonder if it will be possible on the monocrome calc  ::)

In practice, there's not enough memory for nPDF to load most files on monochrome Nspires. :(

I'm sure you'll be able to fix it, also because our device has 64MB of RAM and OS would take only 16 of them :banghead:

@c4ooo unfortunately the problem goes on, I have to accessing through browser that is slow and uncomfortable  :-\
