Simple WebP

=====

Simple WebP is a WebP image decoder in a single source file for easiest integration.

Features

-----

SimpleWebP does:

* Load WebP easily. Loading WebP can be done in 6 lines of code.

* Try to be compatible across all compilers.

* Integrate easily on any C/C++ projects.

* Decode alpha transparency. *

* Decode lossless WebP. *

* Passes all [`libwebp-test-data`](https://chromium.googlesource.com/webm/libwebp-test-data) test vectors. *

\*: Currently not supported, but is the project goal.

SimpleWebP does not:

* Try to be the fastest WebP decoder.

* Support encoding WebP image.

* Support partial decoding (cropping and incremental).

* Support animation (only support decoding first frame).

* Support extracting EXIF/XMP metadata.

Installation

-----

Drop and use `simplewebp.h` in your project. In one (and only one) of your C/C++ source file, define

`SIMPLEWEBP_IMPLEMENTATION` before including `simplewebp.h`.

The license and patent grant of WebM codec is already included in the header file. A separate file `LICENSE.md` and `PATENTS.md` is provided for convenience.

A CMake project is also provided for convenience. You're not required to use it. However, if CMake project is used, there's no need to define `SIMPLEWEBP_IMPLEMENTATION` anywhere. It's automatically handled by CMake.

Quick Example

-----

The "Feature" sections says 6 lines of code right?

```c

size_t width, height;

simplewebp *swebp;

simplewebp_load_from_filename("image.webp", NULL, &swebp);

simplewebp_get_dimensions(swebp, &width, &height);

unsigned char *imageBuffer = malloc(width * height * 4);

simplewebp_decode(swebp, imageBuffer, NULL);

/* `imageBuffer`` now contains decoded RGBA data of the WebP image */

```
