"end coordinates" of a piece of text ?
Aug 3^rd, 2006, 4:38am

Hi again,

Sorry that I didn't ask the previous question correctly enough: how do I find the "end coordinates" of a paragraph?

import processing.opengl.*;

PFont font;
//////////////////////////////////////
TEXTWIDTH txt;
class TEXTWIDTH {
void txtWidth() {
textFont(font, 14);
textLeading(20);

//String s = "this is a paragraph";
String s = "this is a\nparagraph";
float sw = textWidth(s);
//float sh = textLeading(s);
text(s, 10, 50);
stroke(255);
line(sw, 0, sw, 20); // line(sw, sh, sw, sh+20); ?

}
}
//////////////////////////////////////
void setup(){
size(200,200, OPENGL);
txt = new TEXTWIDTH();
font = loadFont("Avenir-Medium-48.vlw");

}

void draw(){
background(0);

txt.txtWidth();

}

You have to add the x coordinate of your text call (text(s, 10, 50); ) to the width of text.

Code:


class TEXTWIDTH {
  void txtWidth() {
    textFont(font, 14);  
    textLeading(20);
     
   
    //String s = "this is a paragraph";
    String s = "this is a\nparagraph";
    float sw = textWidth(s);  
    //float sh = textLeading(s);
    text(s, 10, 50);
    stroke(255);
    line(10+sw, 0, 10+sw, 80); // line(sw, sh, sw, sh+20); ?
     
  }
}
