Encode Command

When encoding, you'll need the io_id of the file you're encoding to, and a encoding preset.

{
    "encode": {
        "io_id": 1,
        "preset": "gif"
    }
}

Jpeg (MozJpeg encoder)

• quality: 0..100 controls the image quality. Consider 80 as a good starting point.
• progressive: true enables progressive jpeg encoding, which takes more CPU time.

{
    "mozjpeg": {
      "quality": 90,
      "progressive": false
    }
}

Gif

"gif"

Lossless PNG

{
  "lodepng": {
    "maximum_deflate": false
  }
}

Lossy PNG

• quality: 0..100 specifies the target quality to aim for.
• minimum_quality: 0.100 specifies the actual quality below which to switch to lossless PNG.
• speed: 1..10 controls the speed/quality tradeoff for encoding.
• maximum_deflate: true gains 1-2% in file size reduction at the expense of a tenfold increase in CPU time.

{
    "pngquant": {
      "quality": 90,
      "minimum_quality": 20,
      "speed": null,
      "maximum_deflate": null
    }
}

WebP (Lossy)

• quality: 0..100 determines the encoding quality. 80 is a good starting point.

{
"webplossy": {
  "quality": 80
}
}

WebP (Lossless)

"webplossless"
