Processing 1.0 - Processing Discourse - text(String, float, float, float, float) BUG!?!?!

text(String, float, float, float, float) BUG!?!?! (Read 515 times)

text(String, float, float, float, float) BUG!?!?!
Aug 28^th, 2008, 10:23am

Here is the bug scenario:

Quote:

String emptyString = " ", longString="is that a bug? Because it's really annoying";
PFont font;
boolean swicth;

void setup(){

  font= loadFont("SagarNormal-25.vlw");
  textFont(font);
  size(560, 560);

}

void draw(){

  background(230);
  fill(0);

  if(!swicth) text(longString, 100, 100, 200, 100);
  else text(emptyString, 100, 100, 200, 100);

}

void mouseReleased(){
  swicth = !swicth;
}

LongString's second line appears when only displaying emptyString. That doesn't happen if only using text(String, float ,float).
Anyone came across that thing ?

It is probably a bug, so you should fill in a bug report in the Contribute section.

I think the issue is that with default vertical align (see textAlign()), text() processes the number of lines fitting in the rectangle, whatever the real number of lines in the string. We don't see this behavior with textAlign(LEFT, CENTER); for example.
And since Processing re-uses buffers between calls of text(), it also re-uses data from previous calls when handling excess lines.
Perhaps a simple reset of the buffers would fix this. Or use the line int lineCount = Math.min(textBreakCount, lineFitCount); in all align modes, but perhaps there is another issue I don't see.

I already filled the bug data base this morning. I've put this bug in the "bug section" of the forum yesterday thinking that if that wasn't a bug and I put it in the bug database that would pissed people off. ( but I did anyway )
It was delete anyway and after searching the forum and bugs database I decided that was a real one and added it to the list. I won't put anything in the bug section any more.

I just added before every textbox a textbox with lots and lots and lots of "spaces" to 'clear' the textBox. Don't know own to reset the textbuffer for a specific textbox, so that's my best trick so far.
