Testing drawimage

Performance Tuning
#1

Hi, just wanted to test performance of drawing a tile as a single image versus cutting the tile from a larger image:

Method 1, single 32*32 image


for(int i = 0; i < 30; i++)
	for(int j = 0; j < 20; j++)
	{
		g.drawImage(img, i*32, j*32, this);
		g.setColor(Color.red);
		g.fillRect(0, 0, 200, 50);
		g.setColor(Color.green);
		g.drawString("FPS: " + fps, 20, 20);
	}

Method 2: 3232 fragment of 512512 image


for(int i = 0; i < 30; i++)
	for(int j = 0; j < 20; j++)
	{
		g.drawImage(img, i*32, j*32, i*32  + 32, j*32 + 32, 0, 0, 32, 32,this);
		g.setColor(Color.red);
		g.fillRect(0, 0, 200, 50);
		g.setColor(Color.green);
		g.drawString("FPS: " + fps, 20, 20);
	}

Conclusion: NO difference at all, I’m a happy camper:)

btw: I think I remember there is a name for this often used method?

#2

“cropping” and “tiling” are some common words for that…
