Thanks to both of you.

The Graphics.drawImage(Image img, int dx1, int dy1, int dx2, int dy2, int sx1, int sy1, int sx2, int sy2, ImageObserver observer); function works perfectly .

Hi,
i'm currently starting a new 2D game project and so far i've always had a fixed 1024x768 screen resolution and fixed locations of things on the screen, but this time i want to make it a bit more dynamic. The user should be able to change it to a resolution that he wants and everything should scale to the wanted size.

Is there a simple way to scale the 2D sprites to another size? Let's say i have a few 1024x768 Jpegs that should now get scaled to a 1920x1080 resolution as soon as the level starts. What's the best way to do that?

As i said, i've always had fixed starting locations like x=256, y=252. How can i adjust these values to the resolution? Should i just work with something like x=frameWidth*(1/4) y=frameHeight*(1/3)  or is there some kind of factor that i could multiply my coordinates with? For example x=256*widthResolutionFactor, y=252*heightResolutionFactor.
