Here are some planned features (in no particular order):
Proper error handling (using MuPDF's C exception handling system)
Zooming
A menu
Allowing the holding down of arrow keys
Find
Rotate page
Some convenient keyboard shortcuts (with help)
Select/copy/paste text (using the Nspire clipboard, i think nTxt has such a feature)

Feel free to post additional suggestions here.

Sounds great, can't wait for your next update! Also, could it have an easy way of going to a certain page? Like instantly getting to page 48 of the Nspire manual, for example.

Can't wait for the next update! I suggest to add page up/page down and to enable the scrolling with the touchpad.

How is the progress on this coming along?

This will be an essential program for all owners of the Nspire. Keep at it we really need this.

Hi Critor,

Does it work if the PDF is just an image? I tried it but did not have success.

I wish there was some sort of documentation or explanation regarding how to use it. In my opinion it is not very straight forward.

What exactly does the Apply button do? Do I use Apply before hitting the Download button?

Once I logged into TI-Planet I filled in the Filename field and description field. I then browsed my machine to where the .pdf was located. I left Lua selected and then I hit the Apply button.

In the bottom left corner of my browser it says "Sending request to tiplanet.org..."

I have tried this quite a few times and it seems to timeout.

Does this mean to not hit the Apply button and instead hit the Download button?

Why is there a File 1 area on the page and a File 2 area? Please explain how to use it. What is the difference between File 1 and File 2? I am a non-French speaker.

I apologize if you think it is intuitive. I just do not seem to follow how to use it.

Thank you in advance.

Nice to see your issue solved but please do not double post.

OK, I completely rewrote nPDF from scratch in C++ over the past few weeks, and I have now released nPDF 0.2.This release is much more stable and supports zooming and proper scrolling. It also uses MuPDF 1.5 which is faster. Next I'll add some keyboard shortcuts.

Source code is now on GitHub.

Binary: https://legimet.github.io/nPDF-0.2.7z
Source tarball: https://legimet.github.io/nPDF-0.2-src.tar.bz2

Cool to have you back Legimet ! Nice update too, never tried either version but I definitely should.

However, I noticed, you're using nspire-ld for linking, which outputs ELF files and the attached binary is a bFLT file 

I'm using an old commit of your Ndless fork.

In your README.md is written: Use Fabian Vogt's fork of Ndless, commit  ac7576f9cc2609789178270d86778a8e45b64464.which is the most recent commit.

Do you think I should use Zehn by concatenating to the resources-loader?

Exceptions will make your life much easier, and it will be a little bit faster (without -fPIE and -fPIC)
There are two downsides though: Startup time will be a bit slower, the file would have to be loaded twice if .bss isn't included and debugging is only supported if you use Zehn without wrapper.
Of course you can simply elf2flt the generated .elf file, and you have both Zehn and bFLT

BTW: You can safely delete and delete[] nullptrs, so every if(ptr) delete ptr; is redundant.

And can you add memory.h? It should just #include string.h.

While you read this, it's already done

Edit: Some suggestions:
    void fillScreen(unsigned char c) {
for (int i = 0; i < SCREEN_WIDTH; i++) {
    for (int j = 0; j < SCREEN_WIDTH; j++) {
setPixel(c, i, j);
    }
}
    }
    void fillScreen(unsigned char r, unsigned char g, unsigned char b) {
for (int i = 0; i < SCREEN_WIDTH; i++) {
    for (int j = 0; j < SCREEN_WIDTH; j++) {
setPixel(r, g, b, i, j);
    }
}
    }
what about std::fill with custom pattern?

void setPixel(unsigned char c, int x, int y) {
// On color models, each pixel is represented in 16-bit high color
// On classic models, each pixel is 4 bits grayscale, 0 is black and 15 is white
if (0 <= x && x < SCREEN_WIDTH && 0 <= y && y < SCREEN_HEIGHT) {
    int pos = y * SCREEN_WIDTH + x;Simple trick to increase performance sigificantly:
"unsigned int x, unsigned int y" obsoletes the comparision "0 <= x".

bool init() {
buf[0] = new unsigned char[SCREEN_BYTES_SIZE];
buf[1] = origBuf;
if (buf[0]) {
    if (std::atexit(deinit)) {
deinit();
return false;
    } else {
atexitCalled = true;
return true;
    }
} else {
    return false;
}
    }Ever heard of global variables? (std::vector could work, too)
