Hi all,
I have written the following method that iterates through all of the pixels of a
BufferedImage,
setting the color of each one based on the output of a procedural texture algorithm.
When I run
it on a 1280x1024 image on my 1.2GHz AMD machine, it takes about 5 seconds to render.
At first I
thought it was my algorithm taking most of the time, but even when I changed it to
just set a
constant color (as shown below; the procedural algorithm call is commented out), the
time is about
the same. I would expect just setting a constant color to be pretty fast. Is there
something I'm
doing in this code that is causing some behind the scenes conversions to happen or is
this
slowness expected? All I want to do is set the RGB values for each pixel, so any
suggestions on
another way to do this are welcome.
Thanks,
Todd Klaus
private void drawImage() {
image = new BufferedImage( getWidth(), getHeight(), BufferedImage.TYPE_INT_RGB
);
Graphics2D g2 = (Graphics2D)image.getGraphics();
if( texture != null ){
for( int x = 0; x < image.getWidth(); x++ ){
for( int y = 0; y < image.getHeight(); y++ ){
float s = ((float)x)/((float)image.getWidth())*sRange;
float t = ((float)y)/((float)image.getHeight())*tRange;
//image.setRGB( x, y, texture.color(s,t).getRGB());
image.setRGB( x, y, Color.red.getRGB());
}
}
}
}
