Hello community,
i am a beginner in processing and i am trying to do a tag cloud but i have a problem with the tags because the words mixed each other when i have transparent background in JAVA2D. I simply want an orange background with my tag cloud with white words.
If somebody can help, thank you very very much.
My code is this:
- PFont font;
- PImage img;
- String fontFile = "Swiss721BT-BoldRounded-48.vlw";//cambie la fuente
- int fSize =96;// a num +alto tags +pequeños por scale de abajo wordSize/fSize
- int maxSize = 50;//int maxSize = 192;
- int minSize = 15;//int minSize = 48;
- String wordFile = "innovacion.txt"; //texto
- String[] words;
- int[] count;
- int most;
- int least;
- float currentSize;
- int currentIndex;
- void setup(){
- size(298,183, JAVA2D);//P2D);
- img = loadImage("degrad.jpg");
- colorMode(HSB, TWO_PI, 1, 1, 1);//modo HSB,matiz 2pi,saturacion, brillo y alpha 0<x>1
- rectMode(CORNER);
- //background(color(PI/6,0.94,0.86));//color de fondo valores entre 0 y 1 gris(0,0,0.7)
- smooth();
- font = loadFont(fontFile);
- initializeWords();
- noLoop();
- }
- void draw()
- {
- image (img,0,0);
- while(currentIndex < words.length) {
- float relsize = map(count[currentIndex],least,most,minSize,maxSize);
- boolean drawn = false;
- while (!drawn) {
- drawn = drawWord(words[currentIndex], relsize);
- if (!drawn)
- println("redrawing "+words[currentIndex]);
- relsize = relsize * 0.95;
- }
- currentIndex++;
- }
- }
- boolean drawWord(String word, float wordSize) {
- int intSize = (int)wordSize;
- textFont(font, wordSize);
- int w = int(textWidth(word));// valor del ancho de la palabra
- PGraphics g = createGraphics(w, intSize, JAVA2D);//P2D);//crea la caja de cada palabra entiendo yo
- g.beginDraw();
- //g.background(color(PI/6,0.94,0.86,0));//fondo de cada palabra,ultimo numero transparencia
- g.fill(color(0,0,99)); //g.fill(color(PI/6,0.94,0.86));//relleno de letra naranja
- g.textAlign(CENTER,CENTER);
- g.translate(w/2, wordSize/2);//traslada a x=anchopalabra/2, y=altoletra/2
- g.scale(wordSize / fSize*2);//(wordSize / fSize);//escala altura/96 mas diferencia entre unas y otras
- g.textFont(font);//fuente
- g.text(word, 0, 0);//palabra y posicion
- g.endDraw();
