I am currently writing a web Interface purely javascript based. I use xtk to display medical image from dicom format. I display 3 viewers : Z, X and Y. I use a canevas to draw on the Z orientation ( in order, for example to encircle an important part of the displayed image).
I would like to make this draw appear on the other orientations ( to have a good idea of what is being encircled). What would be the more convenient way to do it ? can I for example write a label map and then display it using xtk library ? Should I take care of the difference between world coordinate and the image coordinate ?
