Configurable/Selectable canvas color.
Canvas colour being configurable/selectable in the UI will give good value in selfhosted deployments.
Black, White and transparent (glass) are some I can think of. Glass enhances usability when integrated with tools like jitsi during teaching sessions where the teacher can be seen writing from behind the glass. (prototype to that effect is turning out great, can share video as required).
Minor: Whiteout tool need to be modified to match the canvas colour too if this issue is taken up.
The whiteout tool as it is implemented today can only add a new shape, not remove anything. So it wouldn't work with the transparent background.
Hello, I want to change background of canvas, where I should config it ?
It is currently not configurable (hence this issue). The list of server-side configuration options is here: https://github.com/lovasoa/whitebophir/blob/master/server/configuration.js
You could add an option for the default background color here and make a pull request.
