Update PFont.java by dhowe · Pull Request #6132 · processing/processing

This PR adds PFont.textBounds, PFont.textToPoints from p5.js, and PFont.glyphBounds, as shown in the sketch below (there may be more efficient ways to do these). Also, I attempted to use the suggested formatter in Eclipse, but not sure the output is totally correct -- happy to get feedback/improvements...


// DEMO SKETCH

import java.awt.geom.*;

String str = "Lorem ipsum.";
float x = 20, y = 250, fsize = 150;
PFont pf;

void setup() {
  size(1000, 400);
  background(240);

  pf = createFont("Georgia", 300);

  fill(0);
  textFont(pf);
  textSize(fsize);
  text(str, x, y);
  noFill();

  Rectangle2D.Float[] r = pf.glyphBounds(str, x, y, fsize);
  for (int i = 0; i < str.length(); i++) { 
    rect(r[i].x, r[i].y, r[i].width, r[i].height);
  }

  Rectangle2D.Float rb = pf.textBounds(str, x, y, fsize);
  rect(rb.x, rb.y, rb.width, rb.height);

  stroke(200,0,0);
  strokeWeight(3);
  
  PVector[] pts = pf.textToPoints(str, x, y, fsize, 0.5);
  for (int i = 0; i < pts.length; i++) {  
    point(pts[i].x, pts[i].y);
  }
}
