Graphics.drawImage not using specified background color

Question

Thanks to everyone in advance -
I have created an image resizing class, with a crop method. The cropping works great, the issue that I am having is the background color that i specify in the drawImage function of Graphics is not working correctly, it defaults to black as the background regardless of what I supply (in this case Color.WHITE). Also, the overlaying image or top most image (comes from a file) is being inverted(i think it is) or otherwise discolored. Here is the code below that I am working with:
Thanks,
Sam
               public void Crop(int Height, int Width, int SourceX, int SourceY) throws Exception {
                    //output height and width
                    int OutputWidth = this.OutputImage.getWidth();
                    int OutputHeight = this.OutputImage.getHeight();
                    //create output streams
                    ByteArrayOutputStream MyByteArrayOutputStream = new ByteArrayOutputStream();
                    MemoryCacheImageOutputStream MyMemoryCacheImageOutputStream = new MemoryCacheImageOutputStream(MyByteArrayOutputStream);
                    //Create a new  BufferedImage
                    BufferedImage NewImage = new BufferedImage(Width, Height, BufferedImage.TYPE_INT_ARGB);
                    Graphics MyGraphics = NewImage.createGraphics();
                    MyGraphics.drawImage(this.OutputImage, -SourceX, -SourceY, OutputWidth, OutputHeight, Color.WHITE, null);
                    // Get Writer and set compression
                    Iterator MyIterator = ImageIO.getImageWritersByFormatName("PNG");
                    if(MyIterator.hasNext()) {
                         //get image writer
                         ImageWriter MyImageWriter = (ImageWriter)MyIterator.next();
                         //get params
                         ImageWriteParam MyImageWriteParam = MyImageWriter.getDefaultWriteParam();
                         //set outputstream
                         MyImageWriter.setOutput(MyMemoryCacheImageOutputStream);
                         //create new ioimage
                         IIOImage MyIIOImage = new IIOImage(NewImage, null, null);
                         //write new image
                         MyImageWriter.write(null, MyIIOImage, MyImageWriteParam);
                    //convert output stream back to inputstream
                    ByteArrayInputStream MyByteArrayInputStream = new ByteArrayInputStream(MyByteArrayOutputStream.toByteArray());
                    MemoryCacheImageInputStream MyMemoryCacheImageInputStream = new MemoryCacheImageInputStream(MyByteArrayInputStream);
                    //resassign as a buffered image
                    this.OutputImage = ImageIO.read(MyMemoryCacheImageInputStream);
               }

Thanks for all your help!
Here is the solution, notice the clear rect:
               public void Crop(int Height, int Width, int SourceX, int SourceY) throws Exception {
                    //output height and width
                    int OutputWidth = this.OutputImage.getWidth();
                    int OutputHeight = this.OutputImage.getHeight();
                    //Create a new BufferedImage
                    BufferedImage NewImage = new BufferedImage(Width, Height, BufferedImage.TYPE_INT_RGB);
                    //create new grapics
                    Graphics2D MyGraphics = NewImage.createGraphics();
                    //set background
                    MyGraphics.setBackground(Color.decode(this.BackgroundColor));
                    //clear rect
                    MyGraphics.clearRect(0, 0, Width, Height);
                    //draw image
                    MyGraphics.drawImage(this.OutputImage, -SourceX, -SourceY, OutputWidth, OutputHeight, null, null);
                    //dispose graphics
                    MyGraphics.dispose();
                    //resassign as a buffered image
                    this.OutputImage = NewImage;
               }
