problem with loadImage on Windows XP
Oct 3rd, 2005, 5:54pm  
I am helping a student run the following lines of code:

size(400, 400);
PImage bg = loadImage("image.jpg");
background(bg);

and these error messages come up:

java.lang.RuntimeException: openStream() could not open image.jpg

   at processsing.core.PGraphics.requestDisplay(PGraphics.java:362)
   at processsing.core.PApplet.run(PApplet.java:951)
   at java.lang.Thread.run(Unknown Source)

She is running Windows XP, with Java installed.  The image is a jpg, cropped to 400x400 pixels.

The program runs fine on a Mac, and loads the image properly

Other processing sketches (as long as an image isn't trying to load) run fine on this machine.

Thanks

I know this sounds obvious, but is the image stored in the data folder?

looks to me as though the error is to do with locating the file.

yeah - the first thing i checked was to make sure that her image was a jpeg, scaled to the same size as the sketch window, and that it was saved inside of her sketch folder.

i'm guessing it has to do with the fact that processing has trouble loading images outside setup()

so this should work:
PImage bg;
void setup()
{
size(400, 400);
noLoop();
bg = loadImage("image.jpg");
}
void draw()
{
background(bg);
}

nah, cuz a program run in "static" mode is effectively the same as the entire program being smooshed inside setup().

could you post the sketch so we can try on another windows machine? it almost sounds as though there's something screwed up with her java installation if no images are loading properly.
