Setup

Background Images Size
----------------------

These setup must be used in order not to have properly rendered backround image.
Properly rendered means neither grainy not cropped.
This is necessary to cope with a strange konvajs feature: it creates a canvas which is double of the configured stage dimensions, which may result in a grainy exported background image.

Next, the setup for an A3 exported image:

    Background images dimensions    => Real (4962 x 3508)
    
    Json canvas configuration

        Stage dimensions            => Half (2482 x 1754)
        Stage Initial scale         => 0.25

    canvas.js

        Canvas save scale           => 0.5

    toolzoom100.js

        Canvas scale                => 0.5
