noLoop and loading an image
May 13^th, 2005, 4:26pm

Hi,

I'm new here and the first thing I want to say is:Congrats to the creators of Processing and its contributors! It seems to be a wonderfull environment. Considering that I'm coming from C++ land, everything is so clean and simple

So, my question is, what the heck am I doing wrong with this very simple piece of code?

PImage b;

void setup()
{
size(200,200);
noLoop();
b = loadImage("bg.jpg");
image(b, 0, 0);
}

void keyPressed()
{
redraw();
}

void draw()
{
filter(BLUR, 2);
}

I can't imagine it's a bug, but can't see what I'm doing wrong either. I get all kind of strange errors about loading the image. As soon as I remove the noLoop statement, the code runs.

Thanks in advance,
vincent

fjen God Member Offline Posts: 965	Re: noLoop and loading an image Reply #5 - May 13^th, 2005, 8:26pm don't think so. since the basic mode is the same as wrinting all code into setup(){ ... } it should be possible to draw in there ... F

I just discovered some other strange behaviour: every second time i try to compile the code, it does run without errors.

fjen God Member Offline Posts: 965	Re: noLoop and loading an image Reply #7 - May 13^th, 2005, 11:14pm the code i gave above works ... have you tried that? F << update >> move noLoop() to the very end ...

zambal YaBB Newbies Offline Posts: 4	Re: noLoop and loading an image Reply #8 - May 14^th, 2005, 12:12pm yes, i can confirm that if i move the noLoop call to the end of the setup() function, the code works like i intended. thanks! vincent
