We have a PHP Laravel responsive web application(chrome, ie etc.) which has uploaded PDFs and images. On selecting a PDF or image, we want to open PDF or image in another tab or popup and allow at least 5 users to annotate in parallel with one layer of annotation for each user.
The annotation features should include pointing arrows, drawing boxes, adding text boxes and adding pre-saved images on PDFs or Images.
Please share web link if you have done something similar on another project.
