java BufferedImage to int[] issue

Question

I have a BufferedImage (Type.TYPE_INT_ARGB) that I want to convert to a int[]. I do this by using the following method: ((DataBufferInt)src.getRaster().getDataBuffer()).getData();. But when I do this with an image, it gives me the wrong array size. For a 320 x 240 Image it makes a 57,600 size int[] when it should give me a 78,600 size array. Do you know what I am doing wrong?

What's wrong with

src.getRGB(0,0,image.getWidth(),image.getHeight(),null,0,1);

I just use this way because it is the first way I learned. I'll try that now.

"That didn't work" is not helpful. Have a look at the javadoc and play with the parameters a bit - I don't have your code.

It turns out that the source image is supposed to be 320x240 but it is 240x240. My bad

Ugh. And I though I was up late.

It's slow, that's what's wrong with it. :-) (It's not a bad suggestion though, as it will always give the expected results, but at the expense of possible extra color conversion and always array copy).
