Hello,
I am new to ConTeXt and I have looked on the internet for a way to do something special. Unfortunately I have not found any solution.
I hope this is the right place for such a question. I apologise otherwise.
I would like to highlight (e.g. put in bold, or change the color...) any character on a page which sits on a chosen path. I would like to be able to position for instance an invisible circle on a page and have all the characters "in contact" with this circle change color so that the circle become visible via these characters. Is it something I could do with ConTeXt?
If I remember well, there are in pdftex some primitives about (x,y)

Maybe one can use these primitives to dissect a vbox and analyze its nodelist to mark the glyph node that have x y such that | (x-xc)^2 + (y-yc)^2 - r | ⤠đ where (xc,yc) are the coordinate of the circle respect to the page r >0 is the radius đ >0 is the tolerance -- luigi
