Hey everyone! We are looking into this Viewer With Layers (https://msalsbery.github.io/openseadragonmultitester/index.html
) and I have a couple of questions. (1) We are trying to figure out how to allow the user to change the color of each image separately, so that it is possible to pick the desired color for each image, for example, first image is blue, the second is gray, the third is cyan etc. In one old thread @iangilman
had suggested to use pre-draw but I was not able to find any examples. (2) Is it possible to change all the white pixels to transparent ones?
