Thread: Drawing to a Java BufferedImage's graphics producing inaccurate results.

I'm trying to draw one image onto another using graphics.drawImage() but it's only working accurately for some images, others it messes up. My code's below, I've made sure texture is the right image when it enters the method so that's definitely not it. Any ideas?

    public void swapRegionWithTexture(Rectangle region, Image texture) {
        Graphics sheetGraphics = currentSheet.createGraphics();
        for (int ix = region.x; ix < region.x + region.width; ix++) {
            for (int iy = region.y; iy < region.y + region.height; iy++) {
                currentSheet.setRGB(ix, iy, 0x000000);
            }
        }
        sheetGraphics.drawImage(texture, region.x, region.y, null);
        sheetGraphics.dispose();
    }

The general idea is:

1. Grab the graphics to draw to.
2. Clear out the section of the graphics that will be drawn on.
3. Draw the image at the given location on the graphics.
4. Dispose of the graphics.

I've posted this question at Stackoverflow here, but the suggested fix I've gotten so far doesn't work.
I've created an imgur gallery with the before and after here.
