PictureXS tracing
I have just added a canvas to trace over pictures in PictureXS. When you are looking at a particular picture, for example this one, you just have to click on trace in the right side of the head of the page to display the canvas, then trace or annotate, and submit if you want to save your doodle. I still have to add more functionality to the tracing mechanism, but I think for now it’s already fun to play with. Some extras will be easy to do, like hiding the image to see the doodle alone, or browsing only through the images that have been traced over, and other things will be harder, like adding a color palette, undos, or ways to save image files from the drawings. A couple of the things I found myself doing was putting mustaches and beards or devil horns on peoples faces, or making they say funny things with comic book balloons. I think I might implement an extra canvas layer for the censorship, so you could cover things up in a permanent way. But that is a little harder because I might want to merge the drawing with the actual pixels of the image. Maybe one day.
This is where you click to trace:

This is a happy cat:
