Text with charAt and nested iteration

in Programming Questions • 1 year ago

I want to create a text where all letters are touching, like a net, the letterSize should increase from top to bottom 4point per line
this is how far I got, can you help?
It is probably simply "not understanding Java" that is in my way

PFont font;

String atext ="aaaahhh";

void setup(){
size(1000, 1000);
font = loadFont ("Arial.vlw");
textFont(font);
fill(0);
}

void draw(){
background(255);

for (int counter=0; counter < atext.length(); counter++){
for (int fontSize = 10; fontSize< 100; fontSize = fontSize + 4){

x= x+ textWidth(atext);
y= y+ fontSize;
text(atext.charAt(counter),x,y );
if (counter > atext.length()-1) counter = 0;

}
}
}

Thank you!!

here is one way.....

PFont font;
String atext ="aaaahhh";
float x, y;
void setup() {
size(1000, 800);
font = createFont ("Arial.vlw", 12);
textFont(font);
fill(0);
x=200;
}
void draw() {
background(255);
x=200;
y=0;
for (int fontSize = 10; fontSize< 200; fontSize = fontSize + 9) {
for (int counter=0; counter < atext.length(); counter++) {
textSize(fontSize);
text(atext.charAt(counter), x, y );
if (counter > atext.length()-1)
counter = 0;
x+=textWidth(atext.charAt(counter));
}
x = 200;
y= y+ fontSize*.86;
}
}

or...................

PFont font;
String atext ="aaaahhh";
float x, y;
void setup() {
size(1000, 1000);
font = createFont ("Arial.vlw", 12);
textFont(font);
fill(0);
x=0;
}
void draw() {
background(255);
x=0;
y=0;
for (int fontSize = 10; fontSize< 200; fontSize = fontSize + 9) {
while (x<width) {
for (int counter=0; counter < atext.length(); counter++) {
textSize(fontSize);
text(atext.charAt(counter), x, y );
if (counter > atext.length()-1)
counter = 0;
x+=textWidth(atext.charAt(counter));
}
}
x = 0;
y= y+ fontSize*0.99;
}
}

Yes!! The second way is perfect!!
Thank you!!!!!!

Now I tried to insert a pdf record.. but no matter what font I use, it will not accept saying: The font "Sansserif" cannot be used for pdf export.
I use the fonts in other sketches with pdf export though with no problem. Is is a mistake in the code?
Or is there another possibility to work around?

   import processing.pdf.*;
boolean savePDF = false;
    PFont font;
    String atext ="Nothing";
    float x, y;
    void setup() {
      size(700, 500);
      font = createFont ("Arial", 12);
      textFont(font);
      fill(0);
      x=0;
    }
    void draw() {
      if (savePDF) beginRecord(PDF, timestamp()+".pdf");
      background(255);
      x=0;
      y=0;
      for (int fontSize = 10; fontSize< 200; fontSize = fontSize + 9) {
        while (x<width) {
          for (int counter=0; counter < atext.length(); counter++) {
            textSize(fontSize);
            text(atext.charAt(counter), x, y );
            if (counter > atext.length()-1)
              counter = 0;
            x+=(textWidth(atext.charAt(counter))*0.8);
          }
        }
        x = 0;
        y= y+ fontSize*0.55;
            if (savePDF) {
    savePDF = false;
    endRecord();
    }
      }
    }

    void keyReleased() {
if (key == 's' || key == 'S') saveFrame(timestamp()+"_##.png");
if (key == 'p' || key == 'P') savePDF = true;
    }
    String timestamp() {
Calendar now = Calendar.getInstance();
return String.format("%1$ty%1$tm%1$td_%1$tH%1$tM%1$tS", now);
}

Thank you!!
