# hdr2png

A library for various image processing operations.

## Usage

The WASM binary is embedded into the JS module. You can use the
[WASM module](./api.d.ts) directly or a [higher level API](./index.d.ts).

You can find some samples in the [`/test`](./test/) directory.

This library itself isn't multithreaded, but you can kinda achieve it on a
per-file basis by creating multiple instances of the module and using them in
your own workers.

## Building

### Building for WebAssembly

Activate the Emscripten SDK and run `make` in the root directory.

### Building for Win32

You can also build a small CLI executable for testing:

```sh
make -f Makefile.win32
```

This requires clang to be installed and MSVC cannot be used.

You can run it like so:

```sh
.\dist\hdr2png.exe
```

This is chiefly used for testing, but most operations should be available.

## Internal API

See [/src/h2p_lib.h](./src/h2p_lib.h)
