PGraphics text Nov 10th, 2006, 6:39pm   hi all, i'm having a problem using text with a pgraphics object. it displays rectangles instead of the letters. am i missing something here? i am using processing 121 with jikes 1.22 on a fedora core 6 linux machine. thanks in advance. Quote: PFont font; PGraphics p0; void setup() {  size(100, 100, P3D);  font = loadFont("LucidaSans-Demi-48.vlw");  textFont(font, 48);    p0 = createGraphics(width, height, P3D);  p0.beginDraw();  p0.background(255);  p0.fill(0);  p0.textFont(font, 48);  p0.text("xyz", 10, 48);  p0.endDraw(); } void draw() {  image(p0, 0, 0); }

Re: PGraphics text Reply #4 - Nov 10th, 2006, 8:45pm   i'm not sure if it helps, but i found that the words example introduces the same problem if i change the size(200, 200) command to size(200, 200, P2D). this gave me the idea to try the workaround textMode(SCREEN), which seems to work. the pgraphics drawing commands are changed like this: Quote:  p0.beginDraw();  p0.textFont(font, 48);  p0.textMode(SCREEN);  p0.background(255);  p0.fill(0);  p0.text("xyz", 10, 48);  p0.endDraw(); and the text is displayed fine.
