Error due to text

fahadkalis

I am writing a program, to put some text on graphic window. But I am getting below error on it. if I disable text option, it start working well. Can you plz guide me on how do I resolve it.

CODING:-

PImage img;
int pitch=-5; 

void setup() {
  size(448,299, P3D); 
  img=loadImage("imagei.jpg");
  }

void draw() {
  background(img);
  text("ROC   "   + (pitch+5),045,25); 
  }

ERROR:-

Framebuffer error (framebuffer unsupported), rendering will probably not work as expected Read http://wiki.processing.org/w/OpenGL_Issues for help.

Does this work?

PImage img;
int pitch=-5; 

void setup() {
  size(448, 299, P3D); 
  img=loadImage("imagei.jpg");
}

void draw() {
  background(img);
  int temp = pitch + 5;
  text("ROC   " + temp, 045, 25);
}

@TfGuy44 No, I am still facing same error, Do you have any alternative to print Data of graphic window

TfGuy44

The problem is not with your code. Something is wrong with Processing. What machine are you running it on? What version? Was it ever working before?

fahadkalis

I can able to import even STL 3D image and communicate it with serial connection , I am using Processing 2.1.2 version which is very stable for serial communication.

koogs

i think it's looking for a 3d video card and not finding one.

try using a 2d renderer - P2D or JAVA2D rather than P3D.

if you need 3d then i think you're out of luck.

did you read the link it mentions? https://github.com/processing/processing/wiki/OpenGL-Issues

koogs

(elsewhere on the forum posts recommend changing the version of processing you are using. - http://forum.processing.org/two/discussion/8306/application-exported-doesn-t-work-the-application-runs-but-it-doesn-t-show-anything-why )

fahadkalis

Is there any alternative way to display a simple text on graphic window?

fahadkalis

it is very surprise and amazing that... my above coding staring working on Processing version 1.5.

PhiLho

Update your graphic drivers, perhaps. Often works.

fahadkalis

how... I am using intel 82945G chipset?

PhiLho

I don't know. Follow the instructions of Intel and of your system. Google is your friend...
