I haven't tried it, but tt should be compatible.
Calculator just updated to OS 4.5.0.1180, everything is ok as expected.
Would require much time upgrading the MuPDF library? I had high hopes since March  :)

I been searching for hours with no luck on how to convert a .pdf to a .tns to move files onto my TI-Nspire. I have ndless and npdf, however I have no idea how to get the actual .pdf on my calculator. Can somebody please, please help me? All I get is the " an unsupported file was encountered. Only TI-Nspire (.tns) files may be sent to a connected handheld". I would really appreciate it if somebody could send me a link with instructions. Please and Thank you.

Hello all!

I'm with 4.2 SO and already have de ndless and the npdf 0.4b . I'trs all been succesfully installed, but the problem comes when I try to send the documents to the calculator. The computer link recognises de .pdf file and don't let me tranfer the documents. All of you just change the name of the document for document.pdf.tns but in my case it only changes the name and the computer link still recognises that it's a pdf file (it appears documents.pdf.tns.pdf automatically). What should I do to fix this?

thanks, waiting for your answer.

@fgc2 Did you ever get this resolved? I'm having the same issue

You just have to add a .tns extension. The filename should look like "document.pdf.tns" If you're using WIndows Explorer (or whatever it's called nowadays) it might hide the extension and you will need to change a setting to not hide it. I don't know if this is still the case though.

What happens? Does it display an error message? Do other Ndless programs run?

Just the standard ..... "this document format is not supported. ....... even after I add .tns .... opening PDF files is the only Extra thing I am looking to do with the calculator past its normal functions.

OK, what happens when you try to open ndless_resources.tns on the calculator? Does an error message come up?

Ctrl and F should be pressed at the same time.

It seems I've been able to fix the blank/white page issue. muPDF was set for unlimited memory allocation(FZ_STORE) and this caused some issues with larger documents. I've changed FZ_STORE to 16MB and it seems to play nicely now. All of the PDFs that gave me this issue seem to be fine now.

Attached is the tns for the patched version. I've also submitted a pull request on the GitHub for the project.

Please let me know if this works for you! Thanks 



nPDFv0.5b
Hi, I tried this unfortunately I am getting white pages still. I am on OS3_6.

Thanks!

Hello everyone. Sorry to revive an old thread but I need help. I have an nspire cx with ndless 4.4.0 (i upgraded my cx to a cx cas). I'm completely lost on how to download nPDF. I don't have anything installes except for ndless and the cx cas software. Can someone post a step by step run through on how to download it. I downloaded the nPDF.tns file and I ran it in my calculator, but when I try to upload a document from my computer it doesn't even go to the calculator. Again, I would really appreciate it if someone would post a step by step runthrough on how to install and run nPDF.

Thanks!

It's actually really simple: Just rename your file from "something.pdf" to "something.pdf.tns". As far as I know, adding ".tns" at the end of the filename let's you upload any file through the official software!

Hi, I installed ndless and I know it is working because it puts a message on the home screen. Then I installed nPDF and it seems to be working because it posts a message saying that the filetypes are installed. Then I sent over a PDF file to the calculator. However, when I open the PDF file, I get an error saying the filetype is not supported. What am I doing wrong?

Well, this is a six year old program now (or seven, I'm not sure). There's a number of things that could have gone wrong. You could be using a version of the pdf format that is too new for nPDF to read.
Also, please note, that you can't directly open PDF files, and expect the viewer to start automatically, like on windows. You have to first open nPDF and open the file from there using a menu. Good luck!  ;)

When I run nPDF on the calculator, it brings up a message saying "File extensions registered. You can now open a .pdf ... files from the Documents screen." There is no app that remains open with a menu. The PDF I tested with is a very simple one page blank PDF file.
