APNG Assembler

--------------

Simple wrapper around the excellent [APNG Assembler](https://sourceforge.net/projects/apngasm) command line binary.

## Usage

```js

const Assembler = require('apng-assembler');

// Assemble file asynchronously.

Assembler.assemble(

    'input*.png',

    'output.png',

    {

        loopCount: 0,

        frameDelay: 100,

        compression: Assembler.COMPRESS_7ZIP

    }

).then(

    function(outputFile) {

        console.log(`${outputFile} has been assembled successfully.`);

    },

    function(error) {

        console.error(`Failed to assemble: ${error.message}`);

        console.error(`stdout: ${error.stdout}`);

        console.error(`stderr: ${error.stderr}`);

    }

);

// Assemble file synchronously.

try {

    Assembler.assembleSync(

        'input*.png',

        'output.png',

        {

            loopCount: 0,

            frameDelay: 100,

            compression: Assembler.COMPRESS_7ZIP

        }

    );

} catch (e) {

    console.error(`Failed to assemble: ${error.message}`);

    console.error(`stdout: ${error.stdout}`);

    console.error(`stderr: ${error.stderr}`);

}

// Pass an instance of the assembler around.

let assembler = new Assembler.Assembler(loopCount, frameDelay, compression);

assembler.assemble('input*.png', 'output.png');

assembler.assembleSync('input*.png', 'output.png');

```
