# MozJPEG encoder
|
|
|
|
- Source: <https://github.com/mozilla/mozjpeg>
|
|
- Version: v3.3.1
|
|
|
|
## Dependencies
|
|
|

- Docker
|
|
|
|
## Example
|
|
|
|
See `example.html`
|
|
|
|
## API
|
|
|
|
### `int version()`
|
|
|
|
Returns the version of MozJPEG as a number. va.b.c is encoded as 0x0a0b0c
|
|
|
|
### `void free_result()`
|
|
|
|
Frees the result created by `encode()`.
|
|
|
|
### `Uint8Array encode(std::string image_in, int image_width, int image_height, MozJpegOptions opts)`
|
|
|
|
Encodes the given image with given dimension to JPEG. Options looks like this:
|
|
|
|
```c++
|
|
struct MozJpegOptions {
|
|
int quality;
|
|
bool baseline;
|
|
bool arithmetic;
|
|
bool progressive;
|
|
bool optimize_coding;
|
|
int smoothing;
|
|
int color_space;
|
|
int quant_table;
|
|
bool trellis_multipass;
|
|
bool trellis_opt_zero;
|
|
bool trellis_opt_table;
|
|
int trellis_loops;
|
|
bool auto_subsample;
|
|
int chroma_subsample;
|
|
bool separate_chroma_quality;
|
|
int chroma_quality;
|
|
};
|
|
```
