problem resizing image in android

[Suzzane Pinto]

hi,,

iam want to resize my images as per desired height,width thus maintaining the aspect ratio...required height is=800;width=600
my code is

 h=bMap.getHeight();
              	 w=bMap.getWidth();
                 Log.i("oldheight",""+bMap.getHeight());
                 Log.i("oldwidth",""+bMap.getWidth());
                 int destWidth = 600;

             	int destHeight = 800;
             	if(w > h){

            		width = destWidth;

            		height = h*destWidth/w;
            		Log.i(" in if newheight",""+height);
                    Log.i("newwidth",""+width);
                    thumb = Bitmap.createScaledBitmap (thumb, width, height, false);                   
                    ByteArrayOutputStream baos = new ByteArrayOutputStream(); 
             	   thumb.compress(Bitmap.CompressFormat.PNG, 100, baos);
             	   image = baos.toByteArray();

            	} else {

            		height = destHeight;

            		width = w*destHeight/h;
            		Log.i(" in else newheight",""+height);
                    Log.i("newwidth",""+width);
                    thumb = Bitmap.createScaledBitmap (thumb, width, height, false);
                    
                    
                    ByteArrayOutputStream baos = new ByteArrayOutputStream(); 
             	   thumb.compress(Bitmap.CompressFormat.PNG, 100, baos);
             	   image = baos.toByteArray();

            	}

the problem is while i upload my new image with changed height width is not uploaded and the original image is uploaded.
i want to upload only 600*800 of an image.
