How to draw semi-transparent arrow in processing.exe -
how may draw semi-transparent arrow in processing.exe such each arrow uniform in color when on plain background?
this https://processing.org/discourse/beta/num_1219607845.html fails - shows deeper colour shaft , head overlap.
you can use beginshape()
function along vertex()
function draw shape want, including arrows.
here's example the reference:
beginshape(); vertex(20, 20); vertex(40, 20); vertex(40, 40); vertex(60, 40); vertex(60, 60); vertex(20, 60); endshape(close);
you'll have figure out points need draw in order create arrow, can't using lines, since they're going overlap.
alternatively might consider creating image of arrow , drawing image instead.
