textAlign(CENTER, CENTER); bug

in Core Library Questions • 1 year ago

On screen the text is perfect int the center, in the pdf it is not.

Is there a way to solve this problem?

import processing.pdf.*;

PFont font;

void setup() {

size(600, 600);

font = createFont("SansSerif", 15);

smooth();

noLoop();

}

void draw() {

beginRecord(PDF, "output.pdf");

textFont(font);

textSize(15);

textAlign(CENTER, CENTER);

translate(width/2, height/2);

ellipse(0, 0, 70, 70);

fill(0);

text("1140", 0, 0);

endRecord();

}

Hi,

Are you sure ? Just tried your code and for me the text on screen and the one in the pdf file are exactly in the same position. Which version of processing are you using ?

I thought i was using 1.5.1 but apperently i was using 1.5.

Anyway, it's good now althought the CENTER CENTER is not close to being the center in the y axis.

This gives a much better result:

import processing.pdf.*;
PFont font;
void setup() {
size(600, 600);
font = createFont("SansSerif", 15);
smooth();
noLoop();
}
void draw() {
beginRecord(PDF, "output.pdf");
textFont(font);
textSize(15);
textAlign(CENTER, TOP);
translate(width/2, height/2);
ellipse(0, 0, 70, 70);
fill(0);
text("Hjk1140", 0, -textHeight()/2);
fill(255, 0, 0);
ellipse(0, 0, 3, 3);
endRecord();
}
float textHeight() {
return textAscent()+textDescent();
}
