Letters
Drawing letters to the screen in Processing uses a technology developed in the mid 1990s at the Visual Language Workshop at the MIT Media Laboratory. It is a closed system, but we have supplied a number of fonts located in the "font" directory in the main "processing" directory. We expect to change the Processing font technology in the future.
Original Processing.org Example: Letters
// All Examples Written by Casey Reas and Ben Fry
// unless otherwise stated.
size(200, 200);
background(0);
// Load the font. Fonts are located within the
// main Processing directory/folder and they
// must be placed within the data directory
// of your sketch for them to load
PFont fontA = loadFont("Courier New");
textFont(fontA, 36);
textAlign(CENTER);
// Set the gray value of the letters
fill(255);
// Set the left and top margin
int margin = 6;
int gap = 30;
translate(margin*1.5, margin*2);
// Create a matrix of letterforms
int counter = 0;
for(int i=0; i<margin; i++) {
for(int j=0; j<margin; j++) {
char letter;
// Select the letter
int count = 65+(i*margin)+j;
if(count <= 90) {
letter = char(65+counter);
if(letter == 'A' || letter == 'E' || letter == 'I' ||
letter == 'O' || letter == 'U') {
fill(204, 204, 0);
} else {
fill(255);
}
} else {
fill(153);
letter = char(48+counter);
}
// Draw the letter to the screen
text(letter, 15+j*gap, 20+i*gap);
// Increment the counter
counter++;
if(counter >= 26) {
counter = 0;
}
}
