charging an image
May 11th, 2005, 10:32am  
Hi, My name is Mark and It's the firsttime that I use processing. I'm a student that have to do a project with processing.

I wrote the follow simple code:
-----------------------------
PImage bg;
int a;

void setup()
{
 size(487,683);
 framerate(30);  
 bg = loadImage("homePage.jpg");
}

void draw()
{
 background(bg);
 
}
-----------------------------------
My problesm is: how is possible to define a small area in the image background where I can click (with mouse_pressed) and charge a new image (this new image must replace the old one), like an homepage on the web. Please give me a hand.Thank you.

try this one:
http://processing.org/learning/examples/mousefunctions.html

you should load both images inside setup() and keep them in two variables.
inside draw() you check if the mouse is pressed and if it is inside your hotspot-region. if it is you draw the one image, if it is not you just draw the other ...
