Processors

Blurs

To blur an image add this to your layer config:

{
    "name": "box_blur",
    "args": {
        "strength": "6"
    }
}

You can use gaussian blur. As an optional parameter you can adjust radius.

{
    "name": "gaussian_blur",
    "args": {
        "radius": "5.4"
    }
}

Circle processor

This processor will crop a circle out of an image. To use it add this to your conig file:

{
    "name": "circle"
}

It doesn't take any args.

Pop filter

This processor splits image onto 3 color channels and places near each other.

{
    "name": "pop_filter",
    "args": {
        "offset_x": 100,
        "offset_y": 100,
        "increase_factor": 1.4,
        "decrease_factor": 0.8
    }
}

increase and decrease factors change increasing and decreasing incdividual colors for each color chanel.

Print

This processor renders text on an image.

{
  "name": "print",
  "args": {
    "text": "This text created by processor",
    "color": "#FFFFFF",
    "font": "FiraCode-Retina",
    "font_size": 30,
    "start_x": null,
    "start_y": null,
    }
}

you can adjust font and size. Also you can choose x and y coordinates where to start draw.

Radial gradient

This processor creates radial gradient with two colors "inner" and "outer". Inner - color at the center of an image, outer - color at the border.

Variables

uuid4

You can use "{uuid4}" or "{uuid4.hex}" in your config to generate UUIDv4.

most_frequent_color

This variable is used to retrieve most frequent color of an image in hex format.

least_frequent_color

This variable is used to retrieve inverted color to the most frequent one.

It's calculated by inverting the original color.

inverted = (255 - red, 255 - green, 255 - blue)

Also this variable has a synonym "most_frequent_color_inverted".
