Thats so cool, thanks for your help :)

It works - but what if I wanted to put more than one word in the code?

Use an array of words and randomly pick one?
Or be more precise in your question.

yeah..

I did some tests.

Load a picture of you, very small and save it with either 16 colors or 256 colors.
Or all colors.
save as c.bmp in your data folder and then run this:

1. PImage b;
2. // A hashMap
3. HashMap hm = new HashMap();
4. //
5. void setup () {
6.   size (1200, 900);
7.   // Images must be in the "data" directory to load correctly
8.   b = loadImage("c.bmp");
9.   b.loadPixels();
10.   noLoop();
11.   // hashMap
12.   hm.put("000", "#");  // black
13.   hm.put("1281280", "*");
14.   hm.put("13513514", "c"); 
15.   hm.put("135135144", "d");   
16.   hm.put("12800", "e");   
17.   hm.put("200200144", "f");
18.   hm.put("204204204", "g");
19.   hm.put("128128128", "h");
20.   hm.put("192192192", "i");
21.   hm.put("192192", "j");
22.   hm.put("255255255", "."); // white
23. }
24. //
25. void draw () {
26.   image(b, 5, 5);
27.   int x= 125;

Sorry. Yeah I want about 5 or 6 words to be randomly shown like in the first code.. but it only lets me put 1 word.. Sorry if this still doesn't make sense.

easy...

1. PFont f = createFont( "Arial", 24 );
2. String [] myWords  = {
3.   "That", "is", "pretty", "cool", "stuff"
4. };
5. void setup() {
6.   size(400, 400);
7.   textFont(f);
8.   background(0);
9. }
10. void draw() {
11.   fill(random(255), random(255), random(255));
12.   //   text( "" + char( int( random(33, 126) ) ), random(width), random(height) );
13.   text(myWords [ int (random(5))], random(width), random(height) );
14. }

thanks for all your help. it helps a bunch :)

First, usual advice: don't do loadFont() (or loadImage(), etc.) in draw(). It will slow down your sketch and increase a lot the activity of your hard disk! (unless the system caches the file). Beside, no need to do this, the last applied textFont() call is used until a new one is called.

The NPE you get is probably the sign you have not put the background image at the right place. Ensure it is in the data folder of your sketch.

You might want to declare two distinct font variables, and those and the bg declaration should be global, so that you can call background() and textFont() in draw() as well (and load them in setup(), of course).

Well if i take the loadFont out of the draw it doesnt do what i want it to do.. i basically want one big text and then the random small text going around it. and i did have the background image in the data folder. :/

this one works for me.

when you use loadFont you must have the fonts in your data folder;
otherwise use createFont instead (in two places).

It prints now how far it gets in the program so maybe you can tell where the error comes in.
See the pane at the lower screen of the editor. 

1. PFont fontJCfg;
2. PFont fontGiddyupStd;
3. //
4. String [] myWords  = {
5.   "hope", "faith", "creative", "helpful", "loved", "thinker", "friend"
6. };
7. //
8. //
9. void setup() {
10.   // Init
11.   size(656, 414);
12.   println ("starting check");
13.   smooth();
14.   // load image for bg
15.   println ("now doing bg"); 
16.   PImage bg;
17.   bg = loadImage ("butterfly.jpg");
18.   background(bg);
19.   println ("bg check");
20.   //
21.   // the Fonts
22.   // 1st Font
23.   println ("now doing fontJCfg");   
24.   fontJCfg = loadFont("JCfg-48.vlw", 100);
25.   textFont(fontJCfg, 100);
26.   println ("fontJCfg check");
27.   // print text
28.   fill(175, 65, 200);

44. }

look, another one...

ah.. i'm so confused right now lol but thanks for your help

Hello,

sorry, I didn't mean to confuse you.

The second picture (with small texts rotated) is from another program, you can't do it with the one I posted. I hope this didn't confuse you.

In my program - the one I posted - I did what phi.lho said and used two separate fonts.

The comment lines (starting with // ) tell you what's going on.

• The setup() part is rather long and easily understood. It runs only once and prepares everything.
• The draw() part is very short and runs on and on.

The println lines are for finding the error. You can remove them later.

Greetings, Chrisir    

I tried running the code you gave, and I am getting an error..

with loadfont its

without the 
,100
at the end.

Just loadFont ("........");

Ok, so that fixed that problem, but the background still won't work - and yes, its in the same folder as the sketch. 

check
the writing
Butterfly or butterfly,
jpg or bmp.......

quote loadImage()

Loads an image into a variable of type PImage. Four types of images ( .gif, .jpg, .tga, .png) images may be loaded. To load correctly, images must be located in the data directory of the current sketch.

background still isn't working - dont understand why. i guess i wont be using a background

post the most current code?

& its weird because whenever I run it, the only large text there should be is my name "Brittney" but other random words become large as well - anyone know why?

I think kobby helped you very good

here is my old code - you asked for it

  bg = loadImage ("butterfly.jpg");
  background(bg);
  println ("bg check");
  //

  float y = random(15, height-5);
  //
  pushMatrix();
  translate(x, y);
  rotate(radians ( random(0, 359)));
  // when it is not within the rect
  if (! (x > width/2-190 && x < width/2-140 + 280 &&
    y > height/2-120 && y < height/2-80 + 140 )) {
    // paint word
    text( myWords [int (random(5))], 0, 0);
  }
  popMatrix();
  //
  // stop when key

  }
  //
}
// ----------------------------------------------------

when you are in your program / sketch

hit Ctrl-k

a folder opens. Here must be your image.
Or in the data-folder therein.

It must be written exactly like in your sketch, also small and capital letters must be identical...

Thanks for your help but Kobby, your code displays the words way too fast & my name won't show up :/

I got it! Finally...

You are the best!  

 glad you got it to work. Post your code on here so we can see? or on  http://www.openprocessing.org/ so everyone can see.... and send us a link?

see my post (up there at the wrong place) with the butterfly image.
