How do you resize objects?
Jan 17th, 2009, 10:40pm  
Im trying to make a design that has a line that is constantly being resized, but I can't seem to figure out how to make the line shrink/expand.  Anybody know how to resize objects?

There are not "objects" in Processing, although you can define your own (or use some in libraries). Unless you mean SVG shapes...

To your point, if you have a line, it is defined by two points, ie. 2 x/y coordinates. Vary the coordinates, you have a variable size line.

Indeed it is best to relocate your points and update the line. At this moment I am busy with a project that had the same problem, and as far as I know it is best to adjust the pointlocation. You could also probably scale the line, but I think this is more difficult to control correctly.

IE: you have p1 and p2, with line(p1.x, p1.y, p2.x, p2.y).
Now you want to extend the line. Assuming you keep p1 at the same position you have to relocate p2 (p2.x += differenceX, p2.y += difference Y) and update the line by using the new p2 coordinates
