How to animate a large JPG efficiently?
« on: Feb 8^th, 2005, 3:31pm »

Hello everyone, i am new to processing but am trying to make an animation by moving a long thin JPG image across the screen while playing an audio file. i looked through the web site and searched the forums, but could not really find an answer.

i know that this is not what processing is built for, and i believe what i read on these forums that director and flash are good for drawing and processing is good for processing, but i would love to pursue this just as a little exercise.

thank you.

Audio isn't that great on Processing at the moment. You'll need to look at the Sonia library.

To move a jpg, there are lots of resources you could try. Look up the examples/reference for the loadImage() and image() functions and the BImage class to get you started.

I've hit a bit of a wall TomC, I read all of the tech notes you directed me to, and they were great, and I was able to implement each of them in my app, but I was unable to use them to animate the image (simply have it moving accross the screen).

I also couldn't find an example in the exhibitions section. I think what I'm trying to do is just so simple, but I just can't crack it!

I was looking at the examples again, and i was taking a look at the 'motion: linear' ( http://processing.org/learning/examples/linear.html ) and now I am trying desperatley to subsitute the vector line with a JPEG, and let the JPEG (which is larger than the stage) keep moving upwards.

Am I barking up the wrong tree?

I really gotta sort this out, help me I'm drowning!!

I think the image() function should work in your case:

Simply animate the x,y of the upper corner.

Thanks Quasimondo,

would you be able to point me in the way of another example where I can see the animating technique (through changing the X Y values) you are talking about? Thanks heaps again!

-------------------------------

BImage img;

void setup(){
size(200, 200);
img = loadImage("http://iwin.nws.noaa.gov/iwin/images/ecir.jpg");
}

void loop(){
background(0);
image(img, mouseX, mouseY);
}

-------------------------------

BImage img;
int top;

void setup(){
size(200, 200);
top=0;
img = loadImage("http://iwin.nws.noaa.gov/iwin/images/ecir.jpg");
}

void loop(){
background(0);
image(img, 0, top);
top=(top+1)%height;
}
