Hi.
I'm working one a image processing app for Android.
I've got about 27 filters and effect that the user will be able to use.
But i would like to optimize them.
I've made it so the program will resize big images down to 1.2Mp, and I'm running all processing in threads.
But still, a simple invert takes about 5-10 seconds on a real Device (SonyEricsson Xperia Arc, 4.0.3 Stock)

It must be something i can do to optimize speed.

Here is the code i use for inverting the image:

public static Bitmap doInvert(Bitmap src) {
		// Skapa en ny bitmap med samma egenskaper som käll-bilden
		Bitmap bmOut = Bitmap.createBitmap(src.getWidth(), src.getHeight(), src.getConfig());
		// Färg infor
		int A, R, G, B;
		int pixelColor;
		// Bildstorlek
		int height = src.getHeight();
		int width = src.getWidth();

		// Skanna igenom alla pixlarna
	    for (int y = 0; y < height; y++)
	    {
	        for (int x = 0; x < width; x++)
	        {
	        	// Hämta en pixel
	            pixelColor = src.getPixel(x, y);
	            // Spara alpha-kanal
	            A = Color.alpha(pixelColor);
	            // invertera världen för varje R/G/B kanal
	            R = 255 - Color.red(pixelColor);
	            G = 255 - Color.green(pixelColor);
	            B = 255 - Color.blue(pixelColor);
	            // Sätt ny-inverterade pixlarna till slutgiltiga bitmapen
	            bmOut.setPixel(x, y, Color.argb(A, R, G, B)/>);
	        }
	    }

	    // returera slutgiltiga bitmapen
	    return bmOut;
	}

Hope someone would be kind to help me optimize my algorithms and code

Thanks in advance
