Postprocessing for Images

[Lucaffo]

Something like: https://www.w3schools.com/cssref/css3_pr_background-size.php

At the moment, this issue is going to be worked on once we have a solid application. This result can be achieved by the addition of some fields on the json to allow filters. Filters are a fully available option since we use https://pub.dev/packages/image.

Ideally we need a new class "Postprocess" that can be applied to any image.
So you can apply a postprocess to the icon, to the background or to the final result.

(Example: you blur the background but not the overlay icon) A filter can really be anything, even a recolouring. At this point, remember to evaluate the removal of the "colour" param and use filters instead.

Filters:

• Color Multiply
• Vignette
• Sketch
• Smooth
• Sobel
• Sepia
• Pixelate
• Monochrome
• grayscale
• Shadow
• Dithering

The json format should be something like:

{
    "type" : "vignette",
    "any..."
}

The json encode should be check the "type" and convert in the right filter.

[Lucaffo]

Also,

{
    "type" : "recolor",
    "color" : "rgba(255, 255, 0, 1.0)"
}

This should substitute the actual "color" tag

The filter application should be ensured by a strict pipeline
