# Welcome!
**PDF-Nano** is a small(ish) library for generating simple PDF files.

The goal of PDF-Nano is to have a lightweight PDF-library usable from Zig, C and Wasm.

### Features
The main feature is PDF-Nano's small size. Compiled to wasm, it weighs **less than 64kb**, making it suitable for embedded devices.
To keep the code/binary small only a minimal set of features have been and will be added. Currently the following is supported:
- Text (Latin-1 charset support only)
- Basic options for fonts, colors and alignment
- Lines and tables (fixed layout, optionally repeat table header on new page)
- Page numbers in footer
- Jpeg Images (no Jpeg2000 or xl)

Nice to have at some point:
- Unify/improve handling of text/table styles
- Text justify

Not on the todo list (due to code size):
- TrueType fonts (if you need a small library you probably don't have space for fonts anyway)
- Non-jpeg images (as only jpeg is natively supported)
- Compression

### How to build
PDF-Nano is written in Zig, so you will need the Zig compiler. Then simply compile for your target platform (e.g. wasm):

zig build -Doptimize=ReleaseSmall -Dtarget=wasm32-freestanding

### Build compatibility

| v0.1.0       | v0.11.0                    |

### Usage
PDF-Nano provides a text-editor like interface, meaning it handles layouting/positioning for you.
See an [example here](examples/native/main.c).

```c
#include <pdf-nano.h>

int main(int argc, char** argv) {
    encoder_handle handle = createEncoder(A4, PORTRAIT);
    addText(handle, "Hello world!");
    saveAs(handle, "hello.pdf");
    freeEncoder(handle);
    return 0;
}
```

There is also a [typescript wrapper](examples/web/pdf-nano.ts).

### How to add PDF-Nano to your Zig project
To use PDF-Nano via Zig's package manager you can add it as a dependency to your project:

zig fetch --save git+https://github.com/GregorBudweiser/pdf-nano.git

Then in your build.zig file add this:

```zig
const pdf_nano_module = b.dependency("pdf_nano", .{
    .target = target,
    .optimize = optimize,
});
yourModule.addImport("pdf_nano", pdf_nano_module.module("pdf_nano"));
```

Then in your module's zig code you can import it:

```zig
const pdf = @import("pdf_nano");
```
