Hi,
before I'm updating a public API I would like to know if there is any issue
concerning the use of 'drawImage' including Y-flipping as in version 'A'?
What about performance? It seems that both methods, 'A' and 'B', run at the
same speed.
The JPanel and BufferedImage instances have the same size.
[code]
@Override
public void paintComponent(Graphics g) {
super.paintComponent(g);
if (isYUp)
// A.
g.drawImage(bImage,
// Destination rectangle
0, height, width, 0,
// Source rectangle
0, 0, width, height, null);
else
// B.
g.drawImage(bImage, 0, 0, null);
}
[/code]
Are there any alternatives to flip an image during drawing?
My intention is to avoid image copying per 'System.arraycopy(..)' and to save
up to 7 ms per frame during 3D rendering for an image of the size 1500x1100.
Many thanks in advance.
August
