Hi!
`
Graphics g;
DirectGraphics dg;

g=cube[actualCube].getGraphics();
dg=DirectUtils.getDirectGraphics(g);

int format=dg.getNativePixelFormat();

short[] pixels=new short[cubeSize*cubeSize*4];
try {
dg.getPixels(pixels,0,cubeSize*4,0,0,cubeSize*4,cubeSize,format);
}
catch (Exception e) {
System.out.println("Exception(1): "+e+" "+e.getMessage());
}

This code does not what it should do. On every position of pixels[] there is -1 and nothing else. But there is an image in cube[actualCube]. I can see it on the display if it is painted. What can be wrong with this code?

Thanx in advance for any useful help

you need to draw your cube image before grabbing the pixels

e.g

Graphics g;
DirectGraphics dg;

g=cube[actualCube].getGraphics();
dg=DirectUtils.getDirectGraphics(g);


g.drawImage(cube[actualCube], 0, 0, Graphics.TOP | Graphics.LEFT);


int format=dg.getNativePixelFormat();

short[] pixels=new short[cubeSize*cubeSize*4];
try {
dg.getPixels(pixels,0,cubeSize*4,0,0,cubeSize*4,cubeSize,format);
}
catch (Exception e) {
System.out.println("Exception(1): "+e+" "+e.getMessage());
}

Hi!

Now I tried this:

Graphics g;
DirectGraphics dg;

Image tmpCube=Image.createImage(cubeSize*4,cubeSize);
g=tmpCube.getGraphics();
dg=DirectUtils.getDirectGraphics(g);
dg.drawImage(cube[actualCube],0,0,Graphics.TOP|Graphics.LEFT,0);

int format=dg.getNativePixelFormat();

short[] pixels=new short[cubeSize*cubeSize*4];
try {
dg.getPixels(pixels,0,cubeSize*4,0,0,cubeSize*4,cubeSize,format);
}
catch (Exception e) {
System.out.println("Exception(1): "+e+" "+e.getMessage());
}

... but: did not work. I really have no idea why :-((

I think you need to use the same image object to create, get graphics and draw to.

like this:

Graphics g;
DirectGraphics dg;

Image tmpCube=Image.createImage(cubeSize*4,cubeSize);

g=tmpCube.getGraphics();
dg=DirectUtils.getDirectGraphics(g);


g.drawImage(tmpCube, 0, 0, Graphics.TOP | Graphics.LEFT);


int format=dg.getNativePixelFormat();

short[] pixels=new short[cubeSize*cubeSize*4];
try {
dg.getPixels(pixels,0,cubeSize*4,0,0,cubeSize*4,cubeSize,format);
}
catch (Exception e) {
System.out.println("Exception(1): "+e+" "+e.getMessage());
}
