LayerInfos File Structure

Definition

The file should be written as a JSON file that includes a LayerInfos object.

LayerInfos is an array of LayerInfo objects, where formers correspond to lower layers.

LayerInfo is an unordered set of the following key/value pairs:

  • "color_model": ColorModel
  • "comp_op": CompOp
  • "mode": Mode

ColorModel is an unordered set of the following key/value pairs:

  • "primary_color": an array of three numbers corresponding to R, G, and B values
  • "color_variance" : a single number that indicates variance or an array of nine numbers that indicates 3-by-3 covariance matrix

CompOp should be one of the followings:

  • "source-over"
  • "plus"

Mode shoulbe be one of the followings:

  • "Normal"
  • "Multiply"
  • "Screen"
  • "Overlay"
  • "Darken"
  • "Lighten"
  • "ColorDodge"
  • "ColorBurn"
  • "HardLight"
  • "SoftLight"
  • "Difference"
  • "Exclusion"
  • "LinearDodge"

Example

Here is an example of input_layer_info file (a JSON file):

[
  {
    "color_model": {
      "color_variance": 0.10,
      "primary_color": [0.131, 0.131, 0.212]
    },
    "comp_op": "source-over",
    "mode": "Normal"
  },
  {
    "color_model": {
      "color_variance": 0.015,
      "primary_color": [1.000, 0.566, 1.000]
    },
    "comp_op": "source-over",
    "mode": "HardLight"
  },
  {
    "color_model": {
      "color_variance": 0.10,
      "primary_color": [0.283, 0.121, 0.131]
    },
    "comp_op": "source-over",
    "mode": "Multiply"
  }
]
