It was not possible to put on your calculator DOCDOCX (Microsft Word), ODT (OpenOffice Write) or PDF files (Adobe Acrobat).You couldnt either convert those documents to the TI-Nspire document format as it does manage very limited formatting options.
A solution was the conversion of these documents into BMP, JPEG or PNG images. Unfortunately, the TI-Nspire system provides a very limited image reader without any zoom or scrolling support, thus limiting the images to a maximum size of 318x212 pixels inadapted to US letter documents. A solution came with the mViewer image reader for owners of TI-Nspire still able to install Ndless. A drawback of this solution however, was to have a different image for each page, and therefore constantly have to close and reopen images for a document with several pages. ![]() Today, were not going to reduce this inequality, quite the contrary. Because tonight is a great day in the history of the TI- Nspire. Legimet was able to port the MuPDF library and has just released the first third-party document reader for TI-Nspire CX and TI- Nspire CM Named nPDF, it supports PDF, XPS and CBZ documents. But anyway, the program is already 8MB large and wouldnt let you with many space left for those documents on such calculators. Ti Nspire Cx Free Format AndCompered to the previous mViewer solution, advantages of this new player should be: no need to bother looking for a tool to convert your documents to images any more, or even worse to do it manually no need to waste time opening multiple files on the calculator any more before finding the right page of the document I was initially quite skeptical on the PDF support, as it is not a free format and did undergo many changes in years. However, Ive tested several complex documents with many images and tables in addition to the text and have been amazed by an absolutely perfect display For example, here below, reading the 7 th of the 125 pages of the Getting started Started with the TI-Nspire CX TI-Nspire CX CAS Handheld. Even if the nPDF reader is an extraordinary technical performance, it suffers (at least for now) from many drawbacks and limitations: no possibility to zoom no horizontal scrolling (all the pages are automatically scaled to the width of the screen, 320 pixels) no button to skip to the previousnext page (youve got to scroll to the bottomtop of a page in order to move to the nextprevious):( no continuous scrolling (pressing updown arrows just produces a simple little updown scroll, you then have to release the key and repress it, and again and again.):( Small things, whose many would be certainly easy and quick to fix with very gew C code lines, its the matter of a simple weekend, but which for now are going to litterally ruin your user experience, unless youre happy with the video below.:( Note that nPDF did crash here on the last page change. We notice indeed that when were reaching the bottom of a page, the reader can sometimes cross the bottom page which displays some noise lines on the bottom of the screen. This happens with documents whose page height is not a multiple of the vertical scrolling step. At this point, the reader reads random data outside of the memory allocated for the page data, which actually causes such crashes easily. I see that there is no good way to navigate a large pdf as of now, so I encourage the programmer to keep improving this program, as it shows much promise.
