I want to build a website for a specific task and don't really know where to start. Here's what I want to do:
This all seems doable with HTML5 and Javascript - but I've never used either before. Can anyone point me in the right direction or maybe there's already code written that can do all of this I can reuse?
- Allow users to upload a large image, typically 10MP+ (ie larger than screen resolution).
- Users then need to be able to pan around and zoom in and out of the image with the mouse in a reasonable sized box.
- Users need to be able to click on points on the image a dozen times with the pixel coordinates saved.
- A simple calculation needs to be done with these coordinates and the result saved.
- This clicking on points followed by calculation needs to be repeated a few times.
- Finally the results of the calculations are plotted on a graph which can be saved/downloaded as an image.
