Background image framerate drop
Apr 17th, 2009, 7:25am  
Hi,
first of all sorry if this has been posted before or in the wrong section but the search terms for this problem are very common...

is there any way to have a background with an image and not get a huge drop in fps?

since i've added a background .jpg image to my looping sketch the framerate has dropped significantly. i suppose its due to the fact that the image is inside my draw() region and gets reloaded 60times per second (lowering framerate doesn't help). if i put it in the setup region it wont refresh like i need it to. you see my dilemma here...

.svg graphics of the same size work like a charm...maybe a small drop in fps but nothing major like with .jpg...

my computer should be able to handle the load (4gm ram, core2duo 2,1ghz)

thanks in advance

You can load it in setup, and draw it in draw, so you get it refreshing fast, without having  to reload it every frame:

Code:
PImage bg;

void setup()
{
  //... normal setup stuff...
  bg=loadImage("MyBackground.jpg");
}

void draw()
{
  background(bg);
}
